I posted this last week, trying again.
The first patch extends the CFI probe code to get the extended ID from
AMD/Spansion flash chips. I checked with Spansion's support and for AMD or
Spansion devices, a flash device id of 0x7e is always used to indicates an
extended ID is present later on in the CFI query data. There are no
AMD/Spansion chips with a non-extended ID that is the same as another chip's
extended ID. So, once can just replace the normal device id (0x7e) with the
extended one without losing any information. There's nothing to gain by
adding a new field to the flash info struct and then adding code to the fixup
routines to also matches the new field, etc.
The second patch is just a couple simple fixup entries that change the sector
count for the affected flash chips. It uses the extended ID to get the right
chips.
