commit 7a434636dbe199cd85ca22a899d10579d5cd2e66 Author: Stefan Reinauer reinauer@chromium.org Date: Tue May 14 16:57:50 2013 -0700
ARMv7: De-uboot-ify Exynos5250 code
When starting the Exynos5250 port, a lot of unneeded u-boot code was imported. This is an attempt to get rid of a lot of unneeded code before the port is used as a basis for further ARM ports.
There is a lot more that can be done, including cleaning up the 5250's Kconfig file.
