Subject: mtd: spi-nor: Enable locking for n25q512ax3/n25q512a
Git-commit: f3f2b7eb2f1c5889b0a7162b6b5a69c0f357befd
Patch-mainline: v5.7-rc1
References: jsc#SLE-14214 jsc#SLE-16606
n25q512ax3 and n25q512a use the 4 bit Block Protection scheme.
Enable locking for both. Tested on n25q512ax3. The other is modified
following the datasheet.
