[coreboot] denverton_ns: failed to write RW_MRC_CACHE

[Sumo]

Hi,

I'm stuck in a problem where coreboot fails to write the MRC cache in the
SPI Flash.
Below is the log output:

FMAP: area RW_MRC_CACHE found @ 810000 (65536 bytes)
MRC: Checking cached data update for 'RW_MRC_CACHE'.
SF: Detected 00 0000 with sector size 0x1000, total 0x1000000
MRC: no data in 'RW_MRC_CACHE'
MRC: cache data 'RW_MRC_CACHE' needs update.
SPI Transaction Error at Flash Offset 810000 HSFSTS = 0x01046003
REGF metadata allocation failed: 1949 data blocks 4096 total blocks
MRC: failed to update 'RW_MRC_CACHE'.

Any clues?

Thanks,
Sumo
