[U-Boot] [PATCH v1 0/3] Enable DM USB support (host and gadget) in the USB host boot flow

[U-Boot] [PATCH v1 0/3] Enable DM USB support (host and gadget) in the USB host boot flow

[Jean-Jacques Hiblot]

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.

  ARM: DTS: am43xx: Add aliases for the USB ports
  ARM: DTS: am43xx: Enable the DTS entries for USB port #2 in SPL

[U-Boot] [PATCH v1 1/3] ARM: DTS: am43xx: Add aliases for the USB ports

[Jean-Jacques Hiblot]

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.

[U-Boot] [PATCH v1 3/3] configs: am43xx_evm_usbhost_defconfig: Enable DM_USB support

[Jean-Jacques Hiblot]

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.
