From cb5305ac5bac21ec9ff3aadd7c9ca2142bc64c90 Mon Sep 17 00:00:00 2001 From: Tudor Ambarus Date: Fri, 2 Apr 2021 11:20:30 +0300 Subject: [PATCH] Revert "mtd: spi-nor: macronix: Add support for mx25l51245g" commit 46094049a49be777f12a9589798f7c70b90cd03f upstream. This reverts commit 04b8edad262eec0d153005973dfbdd83423c0dcb. 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. If one wants to differentiate the flash names, a better fix would be to differentiate between the two at run-time, depending on SFDP, and choose the correct name from a list of flash names, depending on the SFDP differentiator.
