There is a "K" flavor of this flash which has 512 Byte Page size with 256 KB
Block size. While the page size can be determined by parsing SFDP, I think we 
will have some problems with sector_size because as of now, the sector_size is 
always set to 64KB. An incorrect sector_size will affect erases and locking.

ta

Thanks, I did not noticed that ! If I understand, this will require to modify
the core to handle sector size the same way as page_size and probably add a
fixup to detect the "K" options from SFDP ?
This is probably more changes than I can handle, and you can probably drop this
patch since not really functional for "K" type flash.

But thanks for noticing it !

Right. You can add a post_bfpt fixup hook for this flash. You can 
differentiate between the "K" version and the rest by the page size. Since the 
page size is tightly coupled with the sector size, you can amend both in the 
post_bfpt hook.

I dropped it. You should try to fix it, I can guide you if needed. Or I can do 
it myself, but I'll need some help from you at testing.

Ok, this seems clear ! I'll give it a try. By looking quickly at the code I
think that n_sectors will also have to be updated after discovering the
sector_size from BFPT (for flash size computation). Since some parameters
of the nor are initialized early in spi_nor_info_init_params using
sector_size, should I move the call making use of sector_size later in the
init (in spi_nor_late_init_params for instance) ?

I will try to do it but I will probably only be able to test the patches in a 
couple of weeks due to our architecture not being rebased on 5.7 yet.
