Subject: [PATCH 12/15] mtd: st_spi_fsm: Update Spansion device entries
From: Angus Clark <angus.clark@...com>
This patch updates various Spansion device entries in the flash_types[] table:
- Define full 6-byte READIDs for S25FL128Sx devices (and fix the 4th
byte). This allows us to differentiate between S25FL129P and S25FL128S
devices.
- Add S25FL128Px device entries.
