From 2d7ff858e5f683393f32b07e64e565877a2e4bcb Mon Sep 17 00:00:00 2001 From: Tudor Ambarus Date: Sun, 25 Aug 2019 22:48:36 +0300 Subject: mtd: spi-nor: Add a ->setup() method nor->params.setup() configures the SPI NOR memory. Useful for SPI NOR flashes that have peculiarities to the SPI NOR standard, e.g. different opcodes, specific address calculation, page size, etc. Right now the only user will be the S3AN chips, but other manufacturers can implement it if needed. Move spi_nor_setup() related code in order to avoid a forward declaration to spi_nor_default_setup().
