nxp: fip-handler for additional ddr-fip.bin
Few of the NXP SoC like LX2160A, needs ddr-phy images to be
loaded additionally before DDR initialization
- fip_ddr.bin is created containing upto 6 ddr images.
- With TRUSTED_BOARD_BOOT = 1, fip_ddr.bin is authenticated
first before loading and starting DDR initialization.
- To successfully compile this image, platform-defined header files
needs to be defined:
-- include/common/tbbr/tbbr_img_def.h uses:
--- plat_tbbr_img_def.h: platform specific new FIP image macros.
-- include/tools/share/firmware_image_package.h uses:
--- plat_def_fip_uuid.h: platform specific new UUID macros.
---- Added UUID for DDR images to create FIP-DDR.
---- Added UUID for FUSE provisioning images to create FIP-fuse.
-- include/tools/share/tbbr_oid.h uses:
--- platform_oid.h: platform specific new OID macros.
