Change in coreboot[master]: soc/intel/broadwell/acpi: Use the correct last PCI BUS
by Arthur Heymans (Code Review) 21 Apr '22

The MMCONF_BASE is 0xf000000 so 256 busses is most certainly wrong. The bootblock programs it to 64 busses, so the assumption is that the mrc.bin does not modify that.

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.
