I only quickly went through the patches you sent and saying it's a
repost of the RFC is a bit of a lie. You completely ignored the state
tracking I was trying to do to avoid leaving the flash in 8D mode when
suspending/resetting the board, and I think that part is crucial. If I
remember correctly, we already had this discussion so I must say I'm a
bit disappointed.

Can you sync with Pratyush? I think his series [1] is better in that it
tries to restore the flash in single-SPI mode before suspend (it's
missing the shutdown case, but that can be easily added I think). Of
course that'd be even better to have proper state tracking at the SPI
NOR level.

Regards,

Boris
