[U-Boot] [PATCH 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 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.

We need to be adding USBHOST_BOOT in Kconfig and that's a bit too
generic of a name.  It should perhaps be removed all together and only
set CONFIG_SPL_USB_HOST_SUPPORT for this build and not include it in the
rest.

[U-Boot] [PATCH 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.

The same comments apply here about re-using CONFIG_SPL_ETH_SUPPORT (and
then only set CONFIG_SPL_NET_SUPPORT and anything else).
