I'm going to have to wrestle with buildroot's uboot configuration or
something... But it would be helpful to know what he build error means.

my buildroot .config sets:
BR2_TARGET_UBOOT=y
BR2_TARGET_UBOOT_BOARDNAME="at91sam9g20ek"
BR2_TARGET_UBOOT_CUSTOM_TARBALL=y
BR2_TARGET_UBOOT_CUSTOM_TARBALL_LOCATION="ftp://ftp.denx.de/pub/u-boot/u-boot-2012.10.tar.bz2"
BR2_TARGET_UBOOT_VERSION="custom"
BR2_TARGET_UBOOT_FORMAT_BIN=y
BR2_TARGET_AT91BOOTSTRAP=y
BR2_TARGET_AT91BOOTSTRAP_BOARD="at91sam9g20ek"
BR2_TARGET_AT91BOOTSTRAP_DATAFLASH=y
BR2_TARGET_AT91BOOTSTRAP_MEMORY="dataflash"

uboot build error:

What should the target be?

Maybe my buildroot is also so old it doesn't support the new uboot
configuration syntax?
