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

Remove the authentication size to be a fixed size, due to
recovery.img may be much bigger than the boot.img
Add signature size to boot or recovery image size, which is
added by boot_signer in android build process

boot.img includes kernel image, ramdisk img, dtb, and bootargs.
All are critical for android security. Protect the whole boot.img
with HAB.

Add udc and fastboot support
We did not use the upstream way.
Currently use CI_UDC and USB_GAGDET of upstream can make fastboot work,
but lack of flash operation, so we still use our way.

The fastboot continue command is defined to exit fastboot and continue
autoboot. This commit implements the continue command and the exiting of
fastboot only. Subsequent u-boot commands can be processed after exiting
fastboot. Autoboot should implement a boot script such as "fastboot; mmc
read <...>; bootm" to fully implement the fastboot continue function.

This patch contains an implementation of the fastboot protocol on the
device side and documentation. This is based on USB download gadget
infrastructure. The fastboot function implements the getvar, reboot,
download and reboot commands. What is missing is the flash handling i.e.
writting the image to media.
v3 (Rob Herring):
This is based on http://patchwork.ozlabs.org/patch/126798/ with the
following changes:
- Rebase to current mainline and updates for current gadget API
- Use SPDX identifiers for licenses
- Traced the history and added missing copyright to cmd_fastboot.c
- Use load_addr/load_size for transfer buffer
- Allow vendor strings to be optional
- Set vendor/product ID from config defines
- Allow Ctrl-C to exit fastboot mode
v4:
- Major re-write to use the USB download gadget. Consolidated function
code to a single file.
- Moved globals into single struct.
- Use puts and putc as appropriate.
- Added CONFIG_USB_FASTBOOT_BUF_ADDR and CONFIG_USB_FASTBOOT_BUF_SIZE to
set the fastboot transfer buffer.
v5:
- Add CONFIG option documentation to README
- Rebase using new downloader registration
