MLK-11228-1 android: Integrate community fastboot with FSL i.MX fastboot
1. Replace the UDC driver with community's USB gadget d_dnl driver. 2. Integrate the FSL SD/SATA/NAND flash operations, since the GPT and EFI partitions are not support by i.MX. 3. Add FDT support to community's android image. 4. Change the booti command to boota, due to the booti has been used for ARM64 image boot. 5. Modify boota implementation to load ramdisk and fdt to their loading addresses specified in boot.img header, while bootm won't do it for android image. 6. Modify the android image HAB implementation. Authenticate the boot.img on the "load_addr" for both SD and NAND. 7. Enable new configuration CONFIG_FSL_FASTBOOT for Freescale's fastboot with relevant header file "fsl_fastboot.h". While disabling the configuration, the community fastboot is used. 8. Use community's way to combine cmdline in boot.img and u-boot environment, not overwrite the cmdline in boot.img Signed-off-by: Ye.Li <B37916@freescale.com>
