Change in coreboot[master]: [WIP]soc/intel/icelake: Use SSDT generator to generate PCI _PRT table
by Arthur Heymans (Code Review) 21 Apr '22

21 Apr '22

Arthur Heymans has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/36437 ) Change subject: [WIP]soc/intel/icelake: Use SSDT generator to generate PCI _PRT table ...................................................................... [WIP]soc/intel/icelake: Use SSDT generator to generate PCI _PRT table This creates a _PRT ACPI table using the common southbridge code based on the default routes the FSP sets up. TODO: soc/irq.h can be cleaned up and adapted with this code in mind.

Change in coreboot[master]: nb/intel/nehalen/raminit.c: Run through clang-format
by Arthur Heymans (Code Review) 21 Apr '22

21 Apr '22

Arthur Heymans has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/36084 ) Change subject: nb/intel/nehalen/raminit.c: Run through clang-format ...................................................................... nb/intel/nehalen/raminit.c: Run through clang-format This improves the readability of the raminit a lot, which was likely run through a similar tool to wrap around the old 80 char line limit in the past. TEST: With BUILD_TIMELESS=1 the hash of the resulting binary is identical.

Change in coreboot[master]: nb/intel/nehalem: Introduce macros to reduce indentation level
by Arthur Heymans (Code Review) 21 Apr '22

21 Apr '22

Arthur Heymans has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/36083 ) Change subject: nb/intel/nehalem: Introduce macros to reduce indentation level ...................................................................... nb/intel/nehalem: Introduce macros to reduce indentation level While the indentation of the code is adapted to the new macro's the wrapping is not fixed. A followup commit running this code through clang-format will do that. TEST: build with BUILD_TIMELESS=1, hash of resulting binary is identical before and after.

[RFC]arch/x86: Only allow normal and fallback cbfs prefixes Using other cbfsprefixes is errorprone: It requires a properly formatted cbfs file to be present (an error in the cbfsfile will render the system unbootable) and to correctly enter the cbfs prefix in menuconfig.

Change in ...coreboot[master]: [WIP]Makefile.inc: Add Macro to generate cbfs int files
by Arthur Heymans (Code Review) 21 Apr '22

Arthur Heymans has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/33353 Change subject: [WIP]Makefile.inc: Add Macro to generate cbfs int files ...................................................................... [WIP]Makefile.inc: Add Macro to generate cbfs int files Add the makefile function 'add-cbfs-int' to generate cbfs files containing a little endian integer. Adding cbfs files containing a 64 bit is usually done with cbfstool add-int, but this requires the coreboot.rom image to be already build which clutters the Makefile. Instead add a method to cleanly generate the cbfsfile containing a 64bit little endian int which integrates better with the rest of the makefile.
