Change in libgfxinit[master]: gma registers: Allow to specify an offset for display registers
by Angel Pons (Code Review) 11 Apr '24

11 Apr '24

Angel Pons has uploaded this change for review. ( https://review.coreboot.org/c/libgfxinit/+/44786 ) Change subject: gma registers: Allow to specify an offset for display registers ...................................................................... gma registers: Allow to specify an offset for display registers Certain platforms, namely Bay Trail and Braswell, have the display engine registers at an offset relative to GTTMMADR base. Apart from that, the registers are rather similar to the ones on GMCH platforms. Allow platforms to specify at which offset within GTTMM the display registers are located. Use zero for all currently-supported platforms.

Change in coreboot[master]: arch,toolchain,xcompile: Use GCC as linker
by Jacob Garber (Code Review) 04 Apr '24

04 Apr '24

Jacob Garber has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/40811 ) Change subject: arch,toolchain,xcompile: Use GCC as linker ...................................................................... arch,toolchain,xcompile: Use GCC as linker Code generation when using LTO is not done until after linking, so the compiler must be invoked at all linking stages instead of the linker. Replace $(LD) with GCC, and prefix all linker-specific flags with -Wl so they will be passed to the linker.

Change in coreboot[master]: [TEST] Add support for link time optimization
by Jacob Garber (Code Review) 22 Feb '24

22 Feb '24

Jacob Garber has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/38989 ) Change subject: [TEST] Add support for link time optimization ...................................................................... [TEST] Add support for link time optimization - Code generation is not done until after linking, so the compiler must be invoked at all linking stages instead of the linker. As a consequence all linker arguments must be prefixed with -Wl. - Partial linking is not supported. Instead, object files are collected into thin archives that are linked instead. - The dead_code() macro causes linking errors, since dead functions aren't optimized out until after linking has begun. This macro could be replaced with the preprocessor if necessary, or just disabled for LTO builds. - Wrapping libgcc functions causes a symbol mismatch when using LTO. Wrapping these functions was originally done to support alternate regparam values, though AFAICT this isn't used anywhere. Using LTO leads to a ~10% decrease in stage size for QEMU and ~18% for the Thinkpad T500, and both targets boot successfully.

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.
