Subject: [PATCH 0/2] mtd: spi-nor: macronix: mx25l51245g, mx66l51235l and mx66l51235f

mx25l51245g and mx66l51235l have the same flash ID. The flash
detection returns the first entry in the flash_info array that
matches the flash ID that was read, thus for the 0xc2201a ID,
mx25l51245g was always hit, introducing a regression for
mx66l51235l. Revert mx25l51245g addition. A solution for these
flashes to coexist was proposed.

According to macronix website, there is no mx66l51235l part number.
Rename the part to mx66l51235f.

The difference betwenn mx25l51245g and mx66l51235f flash_info entries
was that mx25l51245g also set SECT_4K. Both flashes support 4K erases,
but the 4K erase should be discovered when parsing BFPT, so there's
no need to set the explicit SECT_4K flag.
