    Subject[PATCH 12/15] mtd: st_spi_fsm: Update Spansion device entries
    Date
    From: Angus Clark <angus.clark@st.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.
