Change in coreboot[master]: arch/x86: Attempt to boot without postcar stage/phase
by Subrata Banik (Code Review) 07 Aug '23

07 Aug '23

Subrata Banik has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/34752 ) Change subject: arch/x86: Attempt to boot without postcar stage/phase ...................................................................... arch/x86: Attempt to boot without postcar stage/phase This patch provides option for soc to exclude postcar (!HAVE_POSTCAR) stage to avoid an additional stage loading and executing time. This effort has 2 benefits: 1. Save boot time by ~4ms 2. Avoid generation of postcar.elf which saves (25kB *3copies = 75kB) of SPI footprint. By current design the postcar stage/phase handles the cache-as-ram tear down and as cache-as-ram is volatile and tearing it down leads to its contents disappearing. Therefore provide a shim layer in ramstage (similar to postcar) to perform below operations: 1. Tears down cache-as-ram with a chipset helper function. 2. Loads and runs ramstage. Because those 2 things are executed out of ram there's no issue of the code's backing store while executing the code that tears down cache-as-ram. The current implementation makes no assumption regarding cacheability of the DRAM itself. If the chipset code wishes to cache DRAM for loading of the ramstage stage/phase then it's also up to the chipset to handle any coherency issues pertaining to cache-as-ram destruction.
