How to read/write SPI flash descriptor
by Li Qiang
Hello all,
I used chipsec to evaluate my hardware.
And I got following report:
[-] Software has write access to SPI flash descriptor
[-] FAILED: SPI flash permissions allow SW to write flash descriptor
I look at the chipsec source code and find that this is read from frap
register(SPIBAR + 50h).
However I can't find the spec how to read the SPI flash descriptor itself.
I find some code from flashrom:
https://github.com/flashrom/flashrom/blob/db7482bb72035fab8386226d1720cde...
It reads SPI flash descriptor using MMIO, but also I don't know how to
write it.(it has no effect when write to the same register with read).
Any hints?
Thanks,
Li Qiang

Hello,
Is anyone currently working on supporting the Intel AlderLake platform for
chipsec? Is it known when chipsec can be used on AlderLake devices?
