Hello May,
My FSP is from Intel website too, but it's called slightly different -
'RANGELEY_*FSP*_POSTGOLD_001_20131218.fd'.
Also, I have the book called "Embedded Firmware Solutions" in which the
purpose of mrc.cache is described as "For saved memory configuration
data." Later in this book there is another mention of this file in the
"State Machine Callbacks" section:
"Each state has an Entry Callback and an Exit Callback, which may be
used by any coreboot code to hook any state. For example the Baytrail
FSP mrc.cache is saved during the table write state, after all devices
have been setup.
Enter State -> Entry Callback -> Execute State -> Exit Callback -> Next
State"
I can also attach my configuration file if it will be more convenient
for you.
