The following patches add support for USB mass storage and USB dfu
bootmodes on am654x-idk.

Because of space constrains and the size of the USB stack,
there are two different usbmsc and usbdfu defconfigs for building R5 SPL.
Fitting both of these into one defconfig requires some changes in the
USB subsystem which is a longer term effort

Faiz Abbas (13):
  spl: usb: Create an API spl_usb_load()
  spl: usb: Only init usb once
  armv7R: K3: am654: Use full malloc in SPL both pre and post reloc
  arm: mach-k3: sysfw-loader: Add support to load SYSFW from USB
  arm: mach-k3: am6_init: Gate mmc related configurations with the
    appropriate config
  arm: mach-k3: am6_init: Do USB fixups to facilitate host and device
    boot modes
  arm: mach-k3: am6_init: Add support for USB boot mode
  arm: dts: k3-am654-r5-base-board: Add USB0 nodes
  arm: dts: k3-am654-base-board: Add support for USB0 in SPL
  configs: am65x_evm: Add support for DFU related configs
  configs: am65x_evm_a53: Enable USB Mass storage and DFU boot modes
  configs: Add new config for supporting USB mass storage boot
