configs: Add fragment config for snagfactory tool
Introduce a new fragment configuration in u-boot to enable support for
the snagfactory tool [1], used for factory flashing of boards. Snagfactory
tool first recovers the board via USB DFU (peripheral boot), and then
uses fastboot to flash given binaries/images to MMC or other on-board
memory via USB. The fragment config can be used to generate boot binaries
for board recovery. This fragment config needs to be added additionally,
while building a53 images for USB DFU boot.
The fragment config enables configurations to allow flashing via
fastboot, manage MMC partitions and boot partitions, customize buffer
size and memory usage for fastboot and also integrate OEM commands and
UUU compatibility. It sets CONFIG_BOOTCOMMAND to start fastboot mode
immediately on startup. It also sets BOOTDELAY to 0 to reduce snagfactory
recovery time. Since BOOTCOMMAND and BOOTDELAY configs are being
modified, these changes cannot be placed in existing DFU fragment config.
Snagfactory used mtd support for flashing both SPI NAND and SPI NOR
devices. The fragment config enables mtd in u-boot and also allows SPI
flash to be treated as an MTD device.
