Not sure if we
want this upstream at all... it's not even
about NOR flash. Just an Intel specific storage format.
Isn't the IFD something similar however? I have to admit I know next to nothing about
IFWI.
Well, the use case is similar: Flash only parts of Intel
firmware. The structure is very different, though, in its
nature. It seems that things can shift and sizes change
when you prep a firmware update, for instance. So, IFD
partitioning is reliable and read-only. IFWI partitioning
is... well, not very nice, unless you have full control
over all firmware parts.

File ifwi.h:
https://review.coreboot.org/#/c/31017/1/ifwi.h@66
PS1, Line 66: #define SPD_MARKER 0x44504324 /* $CPD */
What does the $ character mean?
It's just a
string that marks a valid sub-partition dir. I have no idea
what C, P and D mean, either :) probably something historical.
