intel/common: CAR setup CQOS
Enable CQOS on Geminilake. In Apololake, CBM_LEN is 0x7. Whereas the same in Geminilake is 0xF. Thus get CBM_LEN using cpuid instruction & generate CBM_LEN_MASK. Later use the CBM_LEN_MASK when writing to IA32_L2_MASK_* to set right bits. BUG=None TEST= Build for Geminilake platform i.e., glkrvp & check for successful CAR setup. Even verified the same on APL platform i.e., on Reef Change-Id: Ic736dba1a46629ff5bf3183082799c0c1468e6d9 Signed-off-by: Naresh G Solanki <naresh.solanki@intel.com Reviewed-on: https://review.coreboot.org/21701 Reviewed-by: Aaron Durbin <adurbin@chromium.org> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
