Subject: SPL: Enable use of custom defined U-Boot entry point
X-Git-Tag: v2012.10-rc2~16
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=3c6f8a0d19c0c8e2cee3dae933dbc5a75e29906d;p=u-boot

SPL: Enable use of custom defined U-Boot entry point

By setting CONFIG_SYS_UBOOT_START boards can now use a different entry
point for their U-Boot image. So the U-Boot entry point is not fixed
to CONFIG_SYS_TEXT_BASE any more.
