Change in coreboot[master]: sb/intel/bd82x6x: Rework PCH ID cache
by Angel Pons (Code Review) 18 Jan '24

18 Jan '24

Angel Pons has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/49168 ) Change subject: sb/intel/bd82x6x: Rework PCH ID cache ...................................................................... sb/intel/bd82x6x: Rework PCH ID cache Work around a romstage restriction. Globals (or static variables) cannot be initialized to a non-zero value because there's no data section. Note that the revision ID for stepping A0 is zero, so `pch_silicon_revision` will no longer use the cached value for this PCH stepping. Since it is a pre-production stepping, it is most likely not used anywhere anymore.

Change in coreboot[master]: sb/intel/bd82x6x/pch.c: Extract common functions

Angel Pons has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/49167 ) Change subject: sb/intel/bd82x6x/pch.c: Extract common functions ...................................................................... sb/intel/bd82x6x/pch.c: Extract common functions PCH identification functions and `pch_iobp_update` are used in multiple stages. Move them out of `pch.c` to drop some ugly preprocessor usage. Subsequent commits will use `pch_iobp_update` in romstage as well.

( https://review.coreboot.org/c/coreboot/+/47746 ) Change subject: nb/intel/sandybridge: Refine power-down mode logic ...................................................................... nb/intel/sandybridge: Refine power-down mode logic When memory is running at fast frequencies, power-down modes can lessen system stability. Check tXP and tXPDLL values and use safer power down modes if their values are high. Do not use APD with DLL-off on mobile: vendor firmware does not use it, and it can influence system stability.

Change in coreboot[master]: spi/winbond: Add a test for block protection status bits
by Daniel Gröber (dxld) (Code Review) 29 Sep '23

29 Sep '23

Hello Daniel Gröber, I'd like you to do a code review. Please visit https://review.coreboot.org/c/coreboot/+/42117 to review the following change. Change subject: spi/winbond: Add a test for block protection status bits ...................................................................... spi/winbond: Add a test for block protection status bits With refactoring out of the way we can add a test to make sure the region<>bpbits mapping is correct. Indeed we found that a number of configurations are incorrect. The datasheets say that min/max bp values should protect either all or none of the flash depending on the cmp and tb bits. However we currently always return no protection for these values. The test merely documents the current behavour, a fix will come in a later commit.

Change in coreboot[master]: boot_device: Add boot_device_lockdown
by Patrick Rudolph (Code Review) 28 Sep '23

28 Sep '23

Patrick Rudolph has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/39925 ) Change subject: boot_device: Add boot_device_lockdown ...................................................................... boot_device: Add boot_device_lockdown Add a new method to lock the SPI protected range registers. This allows to lock the SPI controller early, which can be used to write-protect the WP_RO region in bootblock before handing of control to the later stages not protected by WP_RO. In conjunction with VBOOT and BOOTMEDIA_LOCK_CONTROLLER_RO_VBOOT_RO this enables a secure boot mechanism on non CHROMEOS enabled devices.

Hung-Te Lin has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/37262 ) Change subject: util: cbfstool: Add new flag 'ALIGNED' for checking alignment at build time ...................................................................... util: cbfstool: Add new flag 'ALIGNED' for checking alignment at build time Some FMAP sections (for example MRC_VAR_CACHE, RW_DDR_TRAINING, ...) are accessed directly by raw block I/O and must be aligned at SPI flash erase block size (see spi_flash.c#spi_flash_erase_cmd, error "SF: Erase offset/length not multiple of erase size"). If we don't add explicit offset to these sections in FMD files, changing size of other sections may unexpectedly causing them to be unaligned. This patch adds a new flag "ALIGNED" so we can declare a FMAP section as RW_DDR_TRAINING(ALIGNED) 8k to ensure an 8k section that its offset and size will be both aligned at 4k. Note: in current implementation the alignment is fixed at 4k, which is supported on almost all SPI chipsets today. TEST=Change bootblock from default.fmd to BOOTBLOCK(ALIGNED) 127k and build, seeing error message: "E: Section 'BOOTBLOCK'@0[0x1fc00] must be aligned to 0x1000" Change-Id: I26b394590c28667a4afcd521c7caa2009b5b98a9 Signed-off-by: Hung-Te Lin <hungte(a)chromium.org> --- M util/cbfstool/fmap_from_fmd.c M util/cbfstool/fmd.h M util/cbfstool/fmd_parser.c_shipped M util/cbfstool/fmd_parser.h_shipped M util/cbfstool/fmd_parser.y M util/cbfstool/fmd_scanner.c_shipped M util/cbfstool/fmd_scanner.h_shipped M util/cbfstool/fmd_scanner.l 8 files changed, 629 insertions(+), 440 deletions(-) git pull ssh://review.coreboot.org:29418/coreboot refs/changes/62/37262/1 diff --git a/util/cbfstool/fmap_from_fmd.c b/util/cbfstool/fmap_from_fmd.c index 374667a..f822f7b 100644 --- a/util/cbfstool/fmap_from_fmd.c +++ b/util/cbfstool/fmap_from_fmd.c @@ -35,6 +35,18 @@ if (section->flags.f.preserve) flags |= FMAP_AREA_PRESERVE; + if (section->flags.f.aligned) { + /* Currently the alignment is fixed at 4K. */ + const int alignment = 0x1000; + if (absolute_watermark % alignment || + section->size % alignment) { + ERROR("Section '%s'@%#x[%#x] must be aligned to %#x\n", + section->name,absolute_watermark, section->size, + alignment); + return false; + } + } + if (fmap_append_area(flashmap, absolute_watermark, section->size, (uint8_t *)section->name, flags) < 0) { ERROR("Failed to insert section '%s' into FMAP\n", diff --git a/util/cbfstool/fmd.h b/util/cbfstool/fmd.h index 90e6d6e..1eb3a22 100644 --- a/util/cbfstool/fmd.h +++ b/util/cbfstool/fmd.h @@ -33,6 +33,7 @@ struct { int cbfs: 1; /* The section contains a CBFS area. */ int preserve: 1; /* Preserve the section before update. */ + int aligned:1; /* The section must be aligned for block I/O. */ } f; int v; }; diff --git a/util/cbfstool/fmd_parser.c_shipped b/util/cbfstool/fmd_parser.c_shipped index 2597fc6..7a5f34c 100644 --- a/util/cbfstool/fmd_parser.c_shipped +++ b/util/cbfstool/fmd_parser.c_shipped @@ -1,8 +1,9 @@ -/* A Bison parser, made by GNU Bison 3.0.4. */ +/* A Bison parser, made by GNU Bison 3.4.1. */ /* Bison implementation for Yacc-like parsers in C - Copyright (C) 1984, 1989-1990, 2000-2015 Free Software Foundation, Inc. + Copyright (C) 1984, 1989-1990, 2000-2015, 2018-2019 Free Software Foundation, + Inc.

18 Sep '23

Hello Iru Cai, I'd like you to do a code review. Please visit https://review.coreboot.org/c/coreboot/+/44975 to review the following change. Change subject: ec: Add support for MEC5055 for Dell laptops ...................................................................... ec: Add support for MEC5055 for Dell laptops This EC support code is required to boot various Dell Latitude laptops, otherwise the laptop will shut down in a minute after powered on. Tested on Dell Latitude E7240.
