Patch merged into coreboot/master: 211a5d5 armv7/snow: get to romstage
by gerrit＠coreboot.org 18 Jan '13

18 Jan '13

the following patch was just integrated into master: commit 211a5d56db2ecf580b722fab132d908a6ba84dde Author: David Hendricks <dhendrix(a)chromium.org> Date: Thu Jan 17 20:52:21 2013 -0800 armv7/snow: get to romstage This patch does a few things to get us into romstage: - Add romstage as a stage (a later patch adds it as a binary, which is probably wrong). The Makefile magic is complex enough that we let it build the XIP file for now, but we no longer use it. - Replace findstage with loadstage. Loadstage will find a stage, load the code to memory, and zero the remaining part of memory. Now we can link the romstage to go anywhere! - Eliminate magic offsets from code/ldscripts and centralize Kconfig variables in src/cpu/samsung/exynos5250/Kconfig. - Tidy up code and serial output Change-Id: Iae4d2f9e7f429cb1df15d49daf9a08b88d75d79d Signed-off-by: David Hendricks <dhendrix(a)chromium.org> Signed-off-by: Ronald G.

Will this be true for x86 too? I think at minimum it will be MOST, and possibly ALL. ron

I'm delighted that you are interested! This is our first multi-arch port in 10 years. The platform we are porting to is not without its difficulties: - rom is not memory addressed - we don't own the first two stages of firmware, they are binary blobs and one of them is in the mask rom but we have to deal with it, this is how things are going to be on most CPUs in coming years. - we don't have a convenient serial port - no really good jtag path This is one of the harder platforms we've worked with. The guiding principle is to make the ARM port match how we do things in coreboot today:bootblock, romstage, ramstage. But to get here we have to pollute things a bit at first. You see this in the serial port in the bootblock, which we hope to remove sometime next week. I like committing these intermediate targets. This is a good case study of how to do a part, which you can refer to in coming years for new ports. I'd be even happier if we got you folks interested in taking a look at the code too. Just be aware that some of this is pretty kludgy, and will change, but I really want people to see the ugly parts of a port. Just showing a final version would not be as instructive. I doubt we've got time to do a full roadmap, but I have time to answer questions :-) And maybe you can take your -1 off my firmware CL :-) ron -- coreboot mailing list: coreboot(a)coreboot.org http://www.coreboot.org/mailman/listinfo/coreboot

Patch set updated for coreboot: 3518997 AGESA F15tn: Move callouts into northbridge wrapper
by Martin Roth 18 Jan '13

18 Jan '13

Martin Roth (martin.roth(a)se-eng.com) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/2169 -gerrit commit 35189978af7d44fe2771f3fa42a6dd65b10da63a Author: Martin Roth <martin.roth(a)se-eng.com> Date: Thu Jan 17 12:04:08 2013 -0700 AGESA F15tn: Move callouts into northbridge wrapper There are currently too many things in the mainboard directories that are really more suited to being in the northbridge / southbridge wrappers. This is a start at moving some of those functions down into the wrappers. Move the bios callback functions into the northbridge/amd/agesa/family15tn directory from the mainboard directories. These can still be overridden by any mainboard just by updating the pointer in the callback table to point to a customized version of the function.

Patch set updated for coreboot: e728c1c AGESA F15tn: Move callouts into northbridge wrapper
by Martin Roth 18 Jan '13

18 Jan '13

Martin Roth (martin.roth(a)se-eng.com) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/2169 -gerrit commit e728c1c8245cc29140de737555b11f67a01acfac Author: Martin Roth <martin.roth(a)se-eng.com> Date: Thu Jan 17 12:04:08 2013 -0700 AGESA F15tn: Move callouts into northbridge wrapper There are currently too many things in the mainboard directories that are really more suited to being in the northbridge / southbridge wrappers. This is a start at moving some of those functions down into the wrappers. Move the bios callback functions into the northbridge/amd/agesa/family15tn directory from the mainboard directories. These can still be overridden by any mainboard just by updating the pointer in the callback table to point to a customized version of the function.

Patch merged into coreboot/master: 929f9f1 armv7: add a wrapper for romstage's main() for ARM ISA
by gerrit＠coreboot.org 18 Jan '13

18 Jan '13

the following patch was just integrated into master: commit 929f9f171944082240c04507b3f6ac1b0a2c6b1e Author: Gabe Black <gabeblack(a)chromium.com> Date: Thu Jan 17 22:26:36 2013 -0800 armv7: add a wrapper for romstage's main() for ARM ISA This adds a wrapper around main() in romstage which is compiled using -marm. This assumes that the bootblock branches to romstage in ARM mode. The long-term idea is to enforce ABI compatibility when handing off to the next stage by using shims which are which are compiled in a pre- determiend manner and leave the main portions of each stage up to whatever the compiler wants. So it will eventually look like this: 1. bootblock_main (ARM/Thumb) 2. bootblock_exit (ARM) 3. romstage_entry (ARM) 4. romstage_main (ARM/Thumb) (credit to Gabe Black for writing the patch, I'm just uploading it) Change-Id: I4fdb8d2c6c2c0a7178bcb9154c378ddce0567309 Signed-off-by: David Hendricks <dhendrix(a)chromium.org> Signed-off-by: Gabe Black <gabeblack(a)chromium.org> Reviewed-on: http://review.coreboot.org/2175 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.

So it will eventually look like this: 1. bootblock_main (ARM/Thumb) 2. bootblock_exit (ARM) 3. romstage_entry (ARM) 4. romstage_main (ARM/Thumb) (credit to Gabe Black for writing the patch, I'm just uploading it) Change-Id: I4fdb8d2c6c2c0a7178bcb9154c378ddce0567309 Signed-off-by: David Hendricks <dhendrix(a)chromium.org> Signed-off-by: Gabe Black <gabeblack(a)chromium.org> --- src/arch/armv7/Makefile.inc | 15 +++++++++++---- src/arch/armv7/romstage.ld | 1 + src/arch/armv7/romstage_main.c | 29 +++++++++++++++++++++++++++++ src/mainboard/google/snow/romstage.c | 1 + 4 files changed, 42 insertions(+), 4 deletions(-) diff --git a/src/arch/armv7/Makefile.inc b/src/arch/armv7/Makefile.inc index a5833a7..2cf6ed9 100644 --- a/src/arch/armv7/Makefile.inc +++ b/src/arch/armv7/Makefile.inc @@ -264,21 +264,28 @@ endif ################################################################################ # Build the romstage +romstage_main_c = $(src)/arch/armv7/romstage_main.c +romstage_main_o = $(obj)/arch/armv7/romstage_main.o + +$(romstage_main_o): $(romstage_main_c) + @printf " CC $(subst $(obj)/,,$(@))\n" + $(CC) -nostdlib -nostartfiles -static -c -o $@ $< -marm + # FIXME(dhendrix): added debug printfs -$(objcbfs)/romstage_null.debug: $$(romstage-objs) $(objgenerated)/romstage_null.ld +$(objcbfs)/romstage_null.debug: $$(romstage-objs) $(romstage_main_o) $(objgenerated)/romstage_null.ld @printf " LINK $(subst $(obj)/,,$(@))\n" ifeq ($(CONFIG_COMPILER_LLVM_CLANG),y) $(LD) -nostdlib -nostartfiles -static -o $@ -L$(obj) $(romstage-objs) -T $(objgenerated)/romstage_null.ld else - $(CC) -nostdlib -nostartfiles -static -o $@ -L$(obj) -T $(objgenerated)/romstage_null.ld -Wl,--start-group $(romstage-objs) $(LIBGCC_FILE_NAME) -Wl,--end-group + $(CC) -nostdlib -nostartfiles -static -o $@ -L$(obj) -T $(objgenerated)/romstage_null.ld -Wl,--start-group $(romstage-objs) $(romstage_main_o) $(LIBGCC_FILE_NAME) -Wl,--end-group endif $(objcbfs)/romstage_xip.debug: $$(romstage-objs) $(objgenerated)/romstage_xip.ld @printf " LINK $(subst $(obj)/,,$(@))\n" ifeq ($(CONFIG_COMPILER_LLVM_CLANG),y) - $(LD) -nostdlib -nostartfiles -static -o $@ -L$(obj) $(romstage-objs) -T $(objgenerated)/romstage_xip.ld + $(LD) -nostdlib -nostartfiles -static -o $@ -L$(obj) $(romstage-objs) $(romstage_main_o) -T $(objgenerated)/romstage_xip.ld else - $(CC) -nostdlib -nostartfiles -static -o $@ -L$(obj) -T $(objgenerated)/romstage_xip.ld -Wl,--start-group $(romstage-objs) $(LIBGCC_FILE_NAME) -Wl,--end-group + $(CC) -nostdlib -nostartfiles -static -o $@ -L$(obj) -T $(objgenerated)/romstage_xip.ld -Wl,--start-group $(romstage-objs) $(romstage_main_o) $(LIBGCC_FILE_NAME) -Wl,--end-group endif $(objgenerated)/romstage_null.ld: $$(ldscripts) $(obj)/ldoptions diff --git a/src/arch/armv7/romstage.ld b/src/arch/armv7/romstage.ld index 8343a4a..cf69aa7 100644 --- a/src/arch/armv7/romstage.ld +++ b/src/arch/armv7/romstage.ld @@ -45,6 +45,7 @@ SECTIONS .romtext . : { _rom = .; _start = .; + *(.text.entry.armv7); *(.text.startup); *(.text); } diff --git a/src/arch/armv7/romstage_main.c b/src/arch/armv7/romstage_main.c new file mode 100644 index 0000000..0b463b8 --- /dev/null +++ b/src/arch/armv7/romstage_main.c @@ -0,0 +1,29 @@ +/* + * This file is part of the coreboot project. + * + * Copyright (C) 2012 The ChromiumOS Authors.
