Patch set updated for coreboot: skylake: Add initial FSP2.0 support

Rizwan Qureshi (rizwan.qureshi(a)intel.com) just uploaded a new patch set to gerrit, which you can find at https://review.coreboot.org/16267 -gerrit commit 3168d4bda2cd6aa106fed45bbb06008fff84df1c Author: Rizwan Qureshi <rizwan.qureshi(a)intel.com> Date: Tue Aug 23 14:31:23 2016 +0530 skylake: Add initial FSP2.0 support Add Initial pieces of code to support fsp2.0 in skylake keeping the fsp1.1 flow intact. The soc/romstage.h and soc/ramstage.h have a reference to fsp driver includes, so split these header files for each version of FSP driver. Add the below files, car_stage.S: Add romstage entry point (car_stage_entry). This calls into romstage_fsp20.c and aslo handles the car teardown. romstage_fsp20.c: Call fsp_memory_init() and also has the callback for filling memory init parameters. The build was complaining about smaller Bootblock, hence increase the size of bootblock by 4K i.e., set CONFIG_C_ENV_BOOTBLOCK_SIZE to 0x9000 (36K). Also add monotonic_timer.c to verstage. With this patchset and relevant change in kunimitsu mainboard, we are able to boot to romstage. TEST= Build and Boot Kunimitsu with PLATFORM_USES_FSP1_1 Build and Boot Kunimitsu to romstage with PLATFORM_USES_FSP2_0 Change-Id: I4309c8d4369c84d2bd1b13e8ab7bfeaaec645520 Signed-off-by: Rizwan Qureshi <rizwan.qureshi(a)intel.com> --- src/soc/intel/skylake/Kconfig | 3 +- src/soc/intel/skylake/Makefile.inc | 14 ++- src/soc/intel/skylake/chip_fsp20.c | 30 +++++ src/soc/intel/skylake/igd.c | 29 +---- src/soc/intel/skylake/include/fsp11/soc/ramstage.h | 36 ++++++ src/soc/intel/skylake/include/fsp11/soc/romstage.h | 30 +++++ src/soc/intel/skylake/include/fsp20/soc/ramstage.h | 39 ++++++ src/soc/intel/skylake/include/fsp20/soc/romstage.h | 30 +++++ src/soc/intel/skylake/include/soc/ramstage.h | 31 ----- src/soc/intel/skylake/include/soc/romstage.h | 30 ----- src/soc/intel/skylake/include/soc/smm.h | 1 - src/soc/intel/skylake/include/soc/vr_config.h | 9 +- src/soc/intel/skylake/memmap.c | 1 - src/soc/intel/skylake/opregion.c | 49 ++++++++ src/soc/intel/skylake/reset.c | 31 +++++ src/soc/intel/skylake/romstage/Makefile.inc | 5 +- src/soc/intel/skylake/romstage/car_stage.S | 131 +++++++++++++++++++++ src/soc/intel/skylake/romstage/romstage_fsp20.c | 44 +++++++ src/soc/intel/skylake/vr_config.c | 27 +++-- 19 files changed, 461 insertions(+), 109 deletions(-) diff --git a/src/soc/intel/skylake/Kconfig b/src/soc/intel/skylake/Kconfig index 7fa129b..840aded 100644 --- a/src/soc/intel/skylake/Kconfig +++ b/src/soc/intel/skylake/Kconfig @@ -42,6 +42,7 @@ config CPU_SPECIFIC_OPTIONS select RTC select SOC_INTEL_COMMON select SOC_INTEL_COMMON_ACPI_WAKE_SOURCE + select SOC_INTEL_COMMON_GFX_OPREGION if PLATFORM_USES_FSP2_0 select SOC_INTEL_COMMON_LPSS_I2C select SOC_INTEL_COMMON_NHLT select SOC_INTEL_COMMON_RESET @@ -99,7 +100,7 @@ config DCACHE_BSP_STACK_SIZE config C_ENV_BOOTBLOCK_SIZE hex - default 0x8000 + default 0x9000 config EXCLUDE_NATIVE_SD_INTERFACE bool diff --git a/src/soc/intel/skylake/Makefile.inc b/src/soc/intel/skylake/Makefile.inc index b92eab3..aa3da61 100644 --- a/src/soc/intel/skylake/Makefile.inc +++ b/src/soc/intel/skylake/Makefile.inc @@ -28,6 +28,7 @@ bootblock-y += pmutil.c bootblock-y += tsc_freq.c verstage-y += flash_controller.c +verstage-y += monotonic_timer.c verstage-y += pch.c verstage-$(CONFIG_UART_DEBUG) += uart_debug.c @@ -39,12 +40,14 @@ romstage-y += pch.c romstage-y += pcr.c romstage-y += pei_data.c romstage-y += pmutil.c +romstage-$(CONFIG_PLATFORM_USES_FSP2_0) += reset.c romstage-y += smbus_common.c romstage-y += tsc_freq.c romstage-$(CONFIG_UART_DEBUG) += uart_debug.c ramstage-$(CONFIG_HAVE_ACPI_TABLES) += acpi.c -ramstage-y += chip.c +ramstage-$(CONFIG_PLATFORM_USES_FSP1_1) += chip.c +ramstage-$(CONFIG_PLATFORM_USES_FSP2_0) += chip_fsp20.c ramstage-y += cpu.c ramstage-y += cpu_info.c ramstage-y += dsp.c @@ -58,12 +61,14 @@ ramstage-y += lpc.c ramstage-y += me_status.c ramstage-y += memmap.c ramstage-y += monotonic_timer.c +ramstage-$(CONFIG_PLATFORM_USES_FSP1_1) += opregion.c ramstage-y += pch.c ramstage-y += pcie.c ramstage-y += pcr.c ramstage-y += pei_data.c ramstage-y += pmc.c ramstage-y += pmutil.c +ramstage-$(CONFIG_PLATFORM_USES_FSP2_0) += reset.c ramstage-y += ramstage.c ramstage-y += sd.c ramstage-y += smbus.c @@ -92,7 +97,14 @@ smm-$(CONFIG_UART_DEBUG) += uart_debug.c CPPFLAGS_common += -I$(src)/soc/intel/skylake CPPFLAGS_common += -I$(src)/soc/intel/skylake/include + +ifeq ($(CONFIG_PLATFORM_USES_FSP1_1),y) +CPPFLAGS_common += -I$(src)/soc/intel/skylake/include/fsp11 CPPFLAGS_common += -I$(src)/vendorcode/intel/fsp/fsp1_1/skylake +else +CPPFLAGS_common += -I$(src)/soc/intel/skylake/include/fsp20 +CPPFLAGS_common += -I$(src)/vendorcode/intel/fsp/fsp2_0/skykabylake +endif # Currently used for microcode path.

Patch set updated for coreboot: skylake: Add initial FSP2.0 support
by Rizwan Qureshi 24 Aug '16

24 Aug '16

Rizwan Qureshi (rizwan.qureshi(a)intel.com) just uploaded a new patch set to gerrit, which you can find at https://review.coreboot.org/16267 -gerrit commit d89c31e48b37b111606324147a274ee408acf66d Author: Rizwan Qureshi <rizwan.qureshi(a)intel.com> Date: Tue Aug 23 14:31:23 2016 +0530 skylake: Add initial FSP2.0 support Add Initial pieces of code to support fsp2.0 in skylake keeping the fsp1.1 flow intact. The soc/romstage.h and soc/ramstage.h have a reference to fsp driver includes, so split these header files for each version of FSP driver. Add the below files, car_stage.S: Add romstage entry point (car_stage_entry). This calls into romstage_fsp20.c and aslo handles the car teardown. romstage_fsp20.c: Call fsp_memory_init() and also has the callback for filling memory init parameters. memmap.h Includes prototypes for mmap_region_granularity and smm related funtions. These are present in FSP1.1 redefining here for use in FSP2.0 path. The build was complaining about smaller Bootblock, hence increase the size of bootblock by 4K i.e., set CONFIG_C_ENV_BOOTBLOCK_SIZE to 0x9000 (36K). Also add monotonic_timer.c to verstage. With this patchset and relevant change in kunimitsu mainboard, we are able to boot to romstage. TEST= Build and Boot Kunimitsu with PLATFORM_USES_FSP1_1 Build and Boot Kunimitsu to romstage with PLATFORM_USES_FSP2_0 Change-Id: I4309c8d4369c84d2bd1b13e8ab7bfeaaec645520 Signed-off-by: Rizwan Qureshi <rizwan.qureshi(a)intel.com> --- src/soc/intel/skylake/Kconfig | 3 +- src/soc/intel/skylake/Makefile.inc | 14 ++- src/soc/intel/skylake/chip_fsp20.c | 30 +++++ src/soc/intel/skylake/igd.c | 29 +---- src/soc/intel/skylake/include/fsp11/soc/ramstage.h | 36 ++++++ src/soc/intel/skylake/include/fsp11/soc/romstage.h | 30 +++++ src/soc/intel/skylake/include/fsp20/soc/ramstage.h | 39 ++++++ src/soc/intel/skylake/include/fsp20/soc/romstage.h | 30 +++++ src/soc/intel/skylake/include/soc/memmap.h | 47 ++++++++ src/soc/intel/skylake/include/soc/ramstage.h | 31 ----- src/soc/intel/skylake/include/soc/romstage.h | 30 ----- src/soc/intel/skylake/include/soc/smm.h | 3 +- src/soc/intel/skylake/include/soc/vr_config.h | 9 +- src/soc/intel/skylake/memmap.c | 1 - src/soc/intel/skylake/opregion.c | 49 ++++++++ src/soc/intel/skylake/reset.c | 31 +++++ src/soc/intel/skylake/romstage/Makefile.inc | 5 +- src/soc/intel/skylake/romstage/car_stage.S | 131 +++++++++++++++++++++ src/soc/intel/skylake/romstage/romstage_fsp20.c | 44 +++++++ src/soc/intel/skylake/vr_config.c | 27 +++-- 20 files changed, 509 insertions(+), 110 deletions(-) diff --git a/src/soc/intel/skylake/Kconfig b/src/soc/intel/skylake/Kconfig index 7fa129b..840aded 100644 --- a/src/soc/intel/skylake/Kconfig +++ b/src/soc/intel/skylake/Kconfig @@ -42,6 +42,7 @@ config CPU_SPECIFIC_OPTIONS select RTC select SOC_INTEL_COMMON select SOC_INTEL_COMMON_ACPI_WAKE_SOURCE + select SOC_INTEL_COMMON_GFX_OPREGION if PLATFORM_USES_FSP2_0 select SOC_INTEL_COMMON_LPSS_I2C select SOC_INTEL_COMMON_NHLT select SOC_INTEL_COMMON_RESET @@ -99,7 +100,7 @@ config DCACHE_BSP_STACK_SIZE config C_ENV_BOOTBLOCK_SIZE hex - default 0x8000 + default 0x9000 config EXCLUDE_NATIVE_SD_INTERFACE bool diff --git a/src/soc/intel/skylake/Makefile.inc b/src/soc/intel/skylake/Makefile.inc index b92eab3..aa3da61 100644 --- a/src/soc/intel/skylake/Makefile.inc +++ b/src/soc/intel/skylake/Makefile.inc @@ -28,6 +28,7 @@ bootblock-y += pmutil.c bootblock-y += tsc_freq.c verstage-y += flash_controller.c +verstage-y += monotonic_timer.c verstage-y += pch.c verstage-$(CONFIG_UART_DEBUG) += uart_debug.c @@ -39,12 +40,14 @@ romstage-y += pch.c romstage-y += pcr.c romstage-y += pei_data.c romstage-y += pmutil.c +romstage-$(CONFIG_PLATFORM_USES_FSP2_0) += reset.c romstage-y += smbus_common.c romstage-y += tsc_freq.c romstage-$(CONFIG_UART_DEBUG) += uart_debug.c ramstage-$(CONFIG_HAVE_ACPI_TABLES) += acpi.c -ramstage-y += chip.c +ramstage-$(CONFIG_PLATFORM_USES_FSP1_1) += chip.c +ramstage-$(CONFIG_PLATFORM_USES_FSP2_0) += chip_fsp20.c ramstage-y += cpu.c ramstage-y += cpu_info.c ramstage-y += dsp.c @@ -58,12 +61,14 @@ ramstage-y += lpc.c ramstage-y += me_status.c ramstage-y += memmap.c ramstage-y += monotonic_timer.c +ramstage-$(CONFIG_PLATFORM_USES_FSP1_1) += opregion.c ramstage-y += pch.c ramstage-y += pcie.c ramstage-y += pcr.c ramstage-y += pei_data.c ramstage-y += pmc.c ramstage-y += pmutil.c +ramstage-$(CONFIG_PLATFORM_USES_FSP2_0) += reset.c ramstage-y += ramstage.c ramstage-y += sd.c ramstage-y += smbus.c @@ -92,7 +97,14 @@ smm-$(CONFIG_UART_DEBUG) += uart_debug.c CPPFLAGS_common += -I$(src)/soc/intel/skylake CPPFLAGS_common += -I$(src)/soc/intel/skylake/include + +ifeq ($(CONFIG_PLATFORM_USES_FSP1_1),y) +CPPFLAGS_common += -I$(src)/soc/intel/skylake/include/fsp11 CPPFLAGS_common += -I$(src)/vendorcode/intel/fsp/fsp1_1/skylake +else +CPPFLAGS_common += -I$(src)/soc/intel/skylake/include/fsp20 +CPPFLAGS_common += -I$(src)/vendorcode/intel/fsp/fsp2_0/skykabylake +endif # Currently used for microcode path.

Patch set updated for coreboot: skylake: Add initial FSP2.0 support
by Rizwan Qureshi 24 Aug '16

24 Aug '16

Rizwan Qureshi (rizwan.qureshi(a)intel.com) just uploaded a new patch set to gerrit, which you can find at https://review.coreboot.org/16267 -gerrit commit 4e914ccccf8776752f625852080cc8831af95fb8 Author: Rizwan Qureshi <rizwan.qureshi(a)intel.com> Date: Tue Aug 23 14:31:23 2016 +0530 skylake: Add initial FSP2.0 support Add Initial pieces of code to support fsp2.0 in skylake keeping the fsp1.1 flow intact. The soc/romstage.h and soc/ramstage.h have a reference to fsp driver includes, so split these header files for each version of FSP driver. Add the below files, car_stage.S: Add romstage entry point (car_stage_entry). This calls into romstage_fsp20.c and aslo handles the car teardown. romstage_fsp20.c: Call fsp_memory_init() and also has the callback for filling memory init parameters. memmap.h Includes prototypes for mmap_region_granularity and smm related funtions. The build was complaining about smaller Bootblock, hence increase the size of bootblock by 4K i.e., set CONFIG_C_ENV_BOOTBLOCK_SIZE to 0x9000 (36K). Also add monotonic_timer.c to verstage. With this patchset and relevant change in kunimitsu mainboard, we are able to boot to romstage. TEST= Build and Boot Kunimitsu with PLATFORM_USES_FSP1_1 Build and Boot Kunimitsu to romstage with PLATFORM_USES_FSP2_0 Change-Id: I4309c8d4369c84d2bd1b13e8ab7bfeaaec645520 Signed-off-by: Rizwan Qureshi <rizwan.qureshi(a)intel.com> --- src/soc/intel/skylake/Kconfig | 3 +- src/soc/intel/skylake/Makefile.inc | 14 ++- src/soc/intel/skylake/chip_fsp20.c | 30 +++++ src/soc/intel/skylake/igd.c | 29 +---- src/soc/intel/skylake/include/fsp11/soc/ramstage.h | 36 ++++++ src/soc/intel/skylake/include/fsp11/soc/romstage.h | 30 +++++ src/soc/intel/skylake/include/fsp20/soc/ramstage.h | 39 ++++++ src/soc/intel/skylake/include/fsp20/soc/romstage.h | 30 +++++ src/soc/intel/skylake/include/soc/memmap.h | 47 ++++++++ src/soc/intel/skylake/include/soc/ramstage.h | 31 ----- src/soc/intel/skylake/include/soc/romstage.h | 30 ----- src/soc/intel/skylake/include/soc/smm.h | 3 +- src/soc/intel/skylake/include/soc/vr_config.h | 9 +- src/soc/intel/skylake/memmap.c | 1 - src/soc/intel/skylake/opregion.c | 49 ++++++++ src/soc/intel/skylake/reset.c | 31 +++++ src/soc/intel/skylake/romstage/Makefile.inc | 5 +- src/soc/intel/skylake/romstage/car_stage.S | 131 +++++++++++++++++++++ src/soc/intel/skylake/romstage/romstage_fsp20.c | 44 +++++++ src/soc/intel/skylake/vr_config.c | 27 +++-- 20 files changed, 509 insertions(+), 110 deletions(-) diff --git a/src/soc/intel/skylake/Kconfig b/src/soc/intel/skylake/Kconfig index 7fa129b..840aded 100644 --- a/src/soc/intel/skylake/Kconfig +++ b/src/soc/intel/skylake/Kconfig @@ -42,6 +42,7 @@ config CPU_SPECIFIC_OPTIONS select RTC select SOC_INTEL_COMMON select SOC_INTEL_COMMON_ACPI_WAKE_SOURCE + select SOC_INTEL_COMMON_GFX_OPREGION if PLATFORM_USES_FSP2_0 select SOC_INTEL_COMMON_LPSS_I2C select SOC_INTEL_COMMON_NHLT select SOC_INTEL_COMMON_RESET @@ -99,7 +100,7 @@ config DCACHE_BSP_STACK_SIZE config C_ENV_BOOTBLOCK_SIZE hex - default 0x8000 + default 0x9000 config EXCLUDE_NATIVE_SD_INTERFACE bool diff --git a/src/soc/intel/skylake/Makefile.inc b/src/soc/intel/skylake/Makefile.inc index b92eab3..aa3da61 100644 --- a/src/soc/intel/skylake/Makefile.inc +++ b/src/soc/intel/skylake/Makefile.inc @@ -28,6 +28,7 @@ bootblock-y += pmutil.c bootblock-y += tsc_freq.c verstage-y += flash_controller.c +verstage-y += monotonic_timer.c verstage-y += pch.c verstage-$(CONFIG_UART_DEBUG) += uart_debug.c @@ -39,12 +40,14 @@ romstage-y += pch.c romstage-y += pcr.c romstage-y += pei_data.c romstage-y += pmutil.c +romstage-$(CONFIG_PLATFORM_USES_FSP2_0) += reset.c romstage-y += smbus_common.c romstage-y += tsc_freq.c romstage-$(CONFIG_UART_DEBUG) += uart_debug.c ramstage-$(CONFIG_HAVE_ACPI_TABLES) += acpi.c -ramstage-y += chip.c +ramstage-$(CONFIG_PLATFORM_USES_FSP1_1) += chip.c +ramstage-$(CONFIG_PLATFORM_USES_FSP2_0) += chip_fsp20.c ramstage-y += cpu.c ramstage-y += cpu_info.c ramstage-y += dsp.c @@ -58,12 +61,14 @@ ramstage-y += lpc.c ramstage-y += me_status.c ramstage-y += memmap.c ramstage-y += monotonic_timer.c +ramstage-$(CONFIG_PLATFORM_USES_FSP1_1) += opregion.c ramstage-y += pch.c ramstage-y += pcie.c ramstage-y += pcr.c ramstage-y += pei_data.c ramstage-y += pmc.c ramstage-y += pmutil.c +ramstage-$(CONFIG_PLATFORM_USES_FSP2_0) += reset.c ramstage-y += ramstage.c ramstage-y += sd.c ramstage-y += smbus.c @@ -92,7 +97,14 @@ smm-$(CONFIG_UART_DEBUG) += uart_debug.c CPPFLAGS_common += -I$(src)/soc/intel/skylake CPPFLAGS_common += -I$(src)/soc/intel/skylake/include + +ifeq ($(CONFIG_PLATFORM_USES_FSP1_1),y) +CPPFLAGS_common += -I$(src)/soc/intel/skylake/include/fsp11 CPPFLAGS_common += -I$(src)/vendorcode/intel/fsp/fsp1_1/skylake +else +CPPFLAGS_common += -I$(src)/soc/intel/skylake/include/fsp20 +CPPFLAGS_common += -I$(src)/vendorcode/intel/fsp/fsp2_0/skykabylake +endif # Currently used for microcode path.

Patch merged into coreboot/master: drivers/spi: remove unconditional RW boot device initialization
by gerrit＠coreboot.org 24 Aug '16

24 Aug '16

the following patch was just integrated into master: commit 67e4df8b65c0b48717e3550089e7d230aeb6fe52 Author: Aaron Durbin <adurbin(a)chromium.org> Date: Tue Aug 23 08:45:55 2016 -0500 drivers/spi: remove unconditional RW boot device initialization The SPI drivers for the various chipsets are not consistent in their handling of when they are accessible. Coupled with the unknown ordering of boot_device_init() being called this can lead to unexpected behavior (probing failures or hangs). Instead move the act of initializing the SPI flash boot device to when the various infrastructure requires its usage when it calls boot_device_rw(). Those platforms utilizing the RW boot device would need to ensure their SPI drivers are functional and ready when the call happens. This further removes any other systems failing to boot as reported in https://ticket.coreboot.org/issues/67.
