Document support for the Micron MT25QU256A and MT25QU512A Serial NOR FLASHes. Merge the new entries with the existing entry for MT25QU02G. Signed-off-by: Geert Uytterhoeven <geert+renesas@xxxxxxxxx> --- mt25qu512a is already in active use, causing "make dtbs_check" errors. mt25qu256a is supported by the Linux spi-nor driver, but there are no upstream users yet.
Is it encouraged to use the specific compatible with SPI-NOR flashes? As far as I know it isn't. The spi-nor subsys tries hard to identify any flashes at runtime and any additional information in the device tree is used as a last resort (just for flashes which doesn't support the read jedec id command yet). And usually boards have different sources for flash chips, so hardcoding a particular part in the device tree doesn't make sense. just my 2 cents, -michael
