[coreboot] [PATCH] flashrom: Use explicit read function

OK for me.
I can take that into account in my partial read patch.


Carl-Daniel Hailfinger a écrit :
> Flashrom assumes that the flash chip contents are available via mmap if
> no read function is defined. This special case is handled in lots of
> places all over the code.
>
> Remove the special case and supply a jedec_read function. Not only does
> this allow us to fix a read bug in flashrom I recently uncovered on ICH
> SPI, it also allows us to add support for Paraflasher to flashrom.
