For SPI NOR we cleaned the flash info entries in order to have

them slimmer and self explanatory. In order to make the entries
 as slim as possible, we introduced sane default values so that
 the actual flash entries don't need to specify them. We now use
 a flexible macro to specify the flash ID instead of the previous
 INFOx() macros that had hardcoded ID lengths.
 
 Instead of:
 -       { "w25q512nwm", INFO(0xef8020, 0, 64 * 1024, 0)
 -               OTP_INFO(256, 3, 0x1000, 0x1000) },
 
 We now use:
 +               .id = SNOR_ID(0xef, 0x80, 0x20),
 +               .name = "w25q512nwm",
 +               .otp = SNOR_OTP(256, 3, 0x1000, 0x1000),
 
 We also removed some flash entries: the very old Catalyst
 SPI EEPROMs that were introduced once with the SPI-NOR subsystem,
 and a Fujitsu MRAM. Both should use the at25 EEPROM driver.
 The latter even has device tree bindings for the at25 driver.
 
 We made sure that the conversion didn't introduce any unwanted
 changes by comparing the .rodata segment before and after the
 conversion. The patches landed in linux-next immediately after
 v6.6-rc2, we haven't seen any regressions yet.
 
 Apart of the autumn cleaning we introduced a new flash entry,
 at25ff321a, and added block protection support for mt25qu512a.
