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.

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.

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
|
||||||
|
respectively.
