This patchset adds support for the new Keystone 2 Industrial Communication Engine board.
This patchset includes the introduction of embedded FIT images in U-boot. This creates a FIT image of dtb files that enables board specific code to select which DTB to use at runtime. Initially during boot a generic DTB is required that enables board detection to occur and once it has can later be swapped out for the correct dtb.
Franklin S Cooper Jr (28): spl: fit: Break out some functions into a common file boot_fit: Create helper functions that can be used to select DTB out of FIT fdt: Enable selecting correct DTB from append FIT Image ti: common: board_detect: Add function to determine if EEPROM was read dts: Allow OF_LIST to depend on FIT_EMBED arm: dts: Add new "generic" 66AK2Gx device tree file. ti_armv7_keystone2: Define scratch space in SRAM ARM: k2g: Enable TI board detection code board_f: Add new function to allow runtime DTB selection Makefile: Build additional binaries for dtb FIT blobs appended to U-boot ARM: keystone2: Allow to build with all image formats ARM: k2g: Define embedded_dtb_select for runtime DTB selection in U-boot ARM: keystone2: Define board_fit_config_name_match for Keystone 2 boards ks2_evm: Add EEPROM based board detection defconfig: keystone2: Enable U-boot runtime DTB detection ARM: keystone2: Add additional fields used for DDR3 configuration ARM: k2g: Program DDR PHY MR2 register with the default value ARM: k2g: Program DDRPHY_DATX8 registers via mask and value variables ks2_evm: Add EEPROM based board detection helper functions ARM: k2g: Add pinmux support for K2G ICE evm ARM: k2g: Add DDR3 configuration for K2G ICE evm board: ks2: Use board detection to wrap code not specific to K2G ICE evm ARM: k2g: Use board detection to wrap K2G GP specific calls ARM: k2g: Update board_name u-boot env variable at runtime ARM: dts: k2g: Disable netcp by default ARM: dts: k2g: Add DT support for K2G Industrial Communication Engine evm ARM: k2g: Add K2G ICE DTB to the list of possible DTBs defconfig: k2g_evm_defconfig: Add K2G ICE to OF_LIST
Lokesh Vutla (1): ti: common: board_detect: Rename EEPROM scratch start macro
