Merge tag 'spi-nor/for-6.7' into mtd/next
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.
