From 8b4195cd6dc3f1f0ab457d23d21e9f72fde0760a Mon Sep 17 00:00:00 2001 From: Michael Walle Date: Wed, 23 Feb 2022 14:43:47 +0100 Subject: mtd: spi-nor: move all xilinx specifics into xilinx.c Mechanically move all the xilinx functions to its own module. Then register the new flash specific ready() function.

Move all the functions around that into the micron module. This is almost a mechanical move except for the spi_nor_fsr_ready() which now also checks the normal status register. Previously, this was done in spi_nor_ready().
