FWIW, the linux spi nor subsystem will rely more and more on the SFDP
for newer flashes. I had a quick look at qemu's source and command
RDSFDP (0x5a) isn't emulated. Might be worth implementing ;)
Indeed. I really pulled my hair out when mx25l25635_post_bfpt_fixups was
introduced for the MX25L25635F to activate 4B opcodes.
I have sent a patchset adding SFDP support :
http://patchwork.ozlabs.org/project/qemu-devel/list/?series=199024
but Francisco had comments I didn't have time to address.
Anyhow, the series is still in use in the aspeed branch :
https://github.com/legoater/qemu/commits/aspeed-7.0
I can respin.
Thanks,
C.
