2016-08-28 | soc/intel/apollolake: Add CQOS CAR implementation | Andrey Petrov | |
Add new option to set up Cache-As-RAM by using CQOS, Cache Quality of Service. CQOS allows setting ways of cache in no-fill mode, while keeping other ways in regular evicting mode. This effectively allows using CAR and cache simultaneously. BUG=chrome-os-partner:51959 TEST=switch from NEM to CQOS and back, boot Change-Id: Ic7f9899918f94a5788b02a4fbd2f5d5ba9aaf91d Signed-off-by: Andrey Petrov <andrey.petrov@intel.com> Reviewed-on: https://review.coreboot.org/15455 Tested-by: build bot (Jenkins) Reviewed-by: Aaron Durbin <adurbin@chromium.org> | |||
2016-03-23 | soc/intel/apollolake: utilize postcar phase/stage | Aaron Durbin | |
The current Apollolake flow has its code executing out of cache-as-ram for the pre-DRAM stages. This is different from past platforms where they were just executing-in-place against the memory-mapped SPI flash boot media. The implication is that when cache-as-ram needs to be torn down one needs to be executing out of DRAM since the act of cache-as-ram going away means the code disappears out from under the processor. Therefore load and use the postcar infrastructure to bootstrap this process for tearing down cache-as-ram and subsequently loading ramstage.
