* mb, soc: Add the SPD_CACHE_ENABLEZhuohao Lee2022-03-021-2/+3
| | | | | | | | | | | | | | | | | | | | | | In order to cache the spd data which reads from the memory module, we add SPD_CACHE_ENABLE option to enable the cache for the spd data. If this option is enabled, the RW_SPD_CACHE region needs to be added to the flash layout for caching the data. Since the user may remove the memory module after the bios caching the data, we need to add the invalidate flag to invalidate the mrc cache. Otherwise, the bios will use the mrc cache and can make the device malfunction. BUG=b:200243989 BRANCH=firmware-brya-14505.B TEST=build pass and enable this feature to the brask the device could speed up around 150ms with this feature.
