Also mSATA works too BTW.

I'm using the isee git tree u-boot with the following enabled in the

#define IGEPv5_MEMORY_4G
#define FAT_ENV_INTERFACE		"mmc"
#define FAT_ENV_DEVICE			1
#define FAT_ENV_PART			1
#define FAT_ENV_FILE			"uboot.env"

The CONFIG_SUPPORT_RAW_INITRD is needed to support raw initramfs instead of
using mkimage on it for bootz command. I don't think these changes should
affect booting though.

Looks like I only enabled CONFIG_USB_NET_SMSC75XX.

My guess is that you need to play with initrd_high etc, try doing something
like this in u-boot:

setenv fdtaddr 80a00000
setenv loadaddr 80c00000
setenv rdaddr 81400000
setenv fdt_high 8c000000
setenv initrd_high ffffffff

And see if that helps?

BTW, we really need to use initramfs based booting on these for NFS to
avoid having to compile all the USB into the kernel. Well at least for
the mainline omap2plus_defconfig.
