cfi_flash: Read PPB sector protection from device for AMD/Spansion chips Patch 66863b05 [cfi_flash: add support for Spansion flash PPB sector protection] introduced the PPB (Persistent Protection Bit) locking for Spansion chips. But right now the sector protection status (locked vs unlocked) is set to unlocked for all sectors upon bootup. The real sector protection status is ignored. This patch now reads the current sector protection status and uses it for these AMD/Spansion flash chips.
