-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 makes SDHC cards work with the mmc_spi driver.
-
-The problem is that they fail when reading the last block of the card using
-a multi-block read. This is because on SDHC the multiple block read has to be
-stopped with an explicit STOP command, which needs to be sent to the card
-while the incoming transfer is in progress.
-The 2.6.3[45] mmc-spi driver sends it after the last block transfer, so the
-SDHC card continues reading past the end of the card.
-This patch works around this by using single-block reads if we're reading the
-last blocks of the card.

-Some SD-cards fail when doing multiblock read for last block with SPI host. Real
-reason is not known but as workaround we can perform this last read using

-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

-// #define MMC_CHIP_SELECT_GPIO EP93XX_GPIO_LINE_EGPIO15

-Subject: [PATCH] ep93xx: simone: added board specific SPI support for MMC/SD cards
-
-This includes setting up EGPIOs 0 and 9 for card detection and chip select
