From 10ca45d005a96e810b5a225b08135fc24da62ee9 Mon Sep 17 00:00:00 2001 From: Jagannadha Sutradharudu Teki Date: Wed, 2 Oct 2013 19:34:53 +0530 Subject: sf: probe: Add support for SST_WP Most of the SST flashes needs to write up using SST_WP, AAI Word Program, so added a flag param on spi_flash_params table. SST flashes, which supports SST_WP need to use a WP write sst_write_wp instead of common flash write.
