+This patch puts the EP93xx chip revision and unique ID into /proc/cpuinfo.
+This is necessary to be able to set a unique MAC address for DHCP purposes
+by adding a line to /etc/network/interfaces:
+
+# Generate a unique locally-assigned MAC address from the CPU serial number
+pre-up ifconfig eth0 hw ether `sed -n 's/^Serial.* 000000/02/p' /proc/cpuinfo`
+
+It uses the chip revision reading code in the ep93xx-chip-revision patch.
+
+Really, this is wrong, since /proc/cpuinfo should report the revision and
+serial number of the ARM920T processor, while these are the rev and serial
+of the EP93xx SoC. In a future kernel (>2.6.34) there may be a new file
+/proc/socinfo for this information.

+This enables the mmc-over-spi driver for the Sim.One board, based on Mika's
+patch, which used a GPIO for chip select in stead of the default SFRMOUT pin.
+I've modified it to use the usual SFRMOUT; if you've modified your Sim.One
