[U-Boot] [PATCH v2 0/3] Add usb host and ethernet boot support

[Mugunthan V N]

This patch set adds support for usb host boot and
ethernet boot support

Changes from initial version:
* Used standard defines like CONFIG_SPL_USB_HOST_SUPPORT instead
  of introducing new defines as commented by Tom Rini.

  am43xx_evm: add usb host boot support
  am43xx_evm: add eth boot support

[U-Boot] [PATCH v2 1/3] am43xx: Update CONFIG_SPL_TEXT_BASE

[Mugunthan V N]

From: Tom Rini <trini@konsulko.com>

With 1.2 silicon this is now the documented starting usable point for
downloading images to (and corrects a problem with peripheral booting
with prior silicon).  Prior silicon is OK using this address as well.

[U-Boot] [PATCH v2 2/3] am43xx_evm: add usb host boot support

[Mugunthan V N]

While booting via usb host mode, ROM uses DMA to copy MLO over USB so
ARM internal RAM cannot be used. Adding USB host boot support by
introducing new config target which sets SPL_TEXT_BASE to OCMC ram.

[U-Boot] [PATCH v2 3/3] am43xx_evm: add eth boot support

[Mugunthan V N]

add cpsw ethernet boot mode support to download spl and
u-boot.img via tftp protocol. Also adding a seperate config
for ethernet boot mode as the default build falcon mode and
environment on MMC is defined for ethernet boot mode
environment should be set to nowhere.
