-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 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.
