John Schmoller 72fb68d53c xes: Add board_flash_wp_on() ... Add board_flash_wp_on() to check a pca9557 gpio pin to see if non-volatile memory write protection is enabled. Previously, write protected NOR flashes would fail initialization which resulted in a bootup error such as: ... DTT: 53 C local / 64 C remote (adt7461@4c) DTT: 54 C local (ds1621@48) FLASH: Executed from FLASH1 POST memory PASSED FLASH: ## Unknown FLASH on Bank 1 - Size = 0x00000000 = 0 MB ## Unknown FLASH on Bank 2 - Size = 0x00000000 = 0 MB *** failed *** ### ERROR ### Please RESET the board ### With this patch, NOR flash initialization is skipped: ... DTT: 53 C local / 64 C remote (adt7461@4c) DTT: 54 C local (ds1621@48) FLASH: Executed from FLASH1 POST memory PASSED FLASH: Uninitialized - Write Protect On L2: 1024 KB enabled NAND: 1024 MiB ... Note that flash related commands such as flinfo and saveenv will error out when flash write protection is enabled.
