[U-Boot] [PATCH v1 0/3] Enable DM USB support (host and gadget) in the USB host boot flow
The AM43xx is able to get its SPL from an external USB storage. There is a dedicated defconfig (am43xx_evm_usbhost_boot_defconfig) but it doesn't use DM_USB. Converting this defconfig to DM_USB.
Jean-Jacques Hiblot (3): ARM: DTS: am43xx: Add aliases for the USB ports ARM: DTS: am43xx: Enable the DTS entries for USB port #2 in SPL configs: am43xx_evm_usbhost_defconfig: Enable DM_USB support

Although not required, it doesn't hurt to explicitly map the USB ports to a USB controller. Without this, the port number will be derived from the binding order of the peripheral devices.

Applied to u-boot/master, thanks!
This is required to enable the USB port #2 in SPL when DM_USB is used.

Enable DM_USB support in u-boot and in SPL. This brings this configuration closer to am43xx_evm_defconfig.

There is a build issue with this series (forgot to run buildman on this), I'll send a v2 shortly.
