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.

I bought today a new 4GB SDHC card and with that I get similar
errors that you are getting. I hacked around quick fix which seems
to work in my case. I'm wondering whether you could check if it
helps with your SDHC card as well?
This problem is easy to reproduce, just read last sector of the
card (I wrote simple C program but running fdisk -l does the same).
Patch is below.
Thanks,
MW

Subject: [PATCH] mmc_block: use single block reads for last block on SPI
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
multiple single block reads.

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
board to use a GPIO instead, uncomment and modify
// #define MMC_CHIP_SELECT_GPIO EP93XX_GPIO_LINE_EGPIO15
in the source file.
