DA850/OMAP-L138 EMAC driver uses random mac address instead of a fixed one because the mac address is not stuffed into EMAC platform data. This patch provides a function which reads the mac address stored in SPI flash (registered as MTD device) and populates the EMAC platform data. The function which reads the mac address is registered as a callback which gets called upon addition of MTD device. NOTE: In case the MAC address stored in SPI flash is erased, follow the instructions at [1] to restore it. [1] http://processors.wiki.ti.com/index.php/GSG:_OMAP-L138_DVEVM_Additional_Procedures#Restoring_MAC_address_on_SPI_Flash Modifications in v2: Guarded registering the mtd_notifier only when MTD is enabled. Earlier this was handled using mtd_has_partitions() call, but this has been removed in Linux v3.0. Modifications in v3: a. Guarded da850_evm_m25p80_notify_add() function and da850evm_spi_notifier structure with CONFIG_MTD macros. b. Renamed da850_evm_register_mtd_user() function to da850_evm_setup_mac_addr() and removed the struct mtd_notifier argument to this function. c. Passed the da850evm_spi_notifier structure to register_mtd_user() function. Modifications in v4: Moved the da850_evm_setup_mac_addr() function within the first CONFIG_MTD ifdef construct.
