[coreboot] RW_MRC_CACHE always displays needs update and boot time is more

[Moorthi M.s]

Hi,

I am developing coreboot (ver 4.17) along with UEFI payload for a custom
board derived from CFL H RVP11 CRB.

I included the CACHE_MRC_SETTINGS to reduce the boot time on subsequent
power on.

But the time was not reducing and on every power on, around 18 seconds are
taking between post code 0x92 (Ram Init) and 0x98 (Ram Init Exit). And
always prints as " MRC: cache data 'RW_MRC_CACHE' needs update".

Because of this coreboot takes around 45 secs to boot.

Why everytime the MRC cache data is changing? Why the processor is not
using the MRC cached data?

Is there any other configurations needs to be done?
