+
+Add support for correctly configuring the fref_clkout depending on the
+board revision of the pandaboard. This patch is necessary to make u-boot
+work with the smsc usb+ethernet driver.
+
+Tested USB+Eth with TFTP and PXE using linaro u-boot:
+http://git.linaro.org/gitweb?p=boot/u-boot-linaro-stable.git;a=summary
+
+Based on patch from David Anders <x0132446@ti.com> from
+omap4_panda_L24.9 branch at gitorious.org/pandaboard x-loader tree.
+
+Changes since v1:
+ * Moving the code from s_init instead of adding a new block
