-+*
-+* "data" points to an array of pixels that define the cursor; each row should
-+* be a multiple of 32-bit values (i.e. 16 pixels). Each pixel is two bits,
-+* where the values are:
-+*
-+* 00 => transparent 01 => invert 10 => color1 11 => color2
-+*
-+* The data is arranged as follows (per word):
-+*
-+* bits: |31-30|29-28|27-26|25-24|23-22|21-20|19-18|17-16|
-+* pixel: | 12 | 13 | 14 | 15 | 8 | 9 | 10 | 11 |
-+* bits: |15-14|13-12|11-10| 9-8 | 7-6 | 5-4 | 3-2 | 1-0 |
-+* pixel: | 4 | 5 | 6 | 7 | 0 | 1 | 2 | 3 |
-+*
-+* Regardless of the frame buffer color depth, "color1", "color2",
-+* "blinkcolor1", and "blinkcolor2" are 24-bit colors since the cursor is
-+* injected into the data stream right before the video DAC.
-+*
-+* When "blinkrate" is not zero, pixel value 10 will alternate between "color1"
-+* and "blinkcolor1" (similar for pixel value 11 and "color2"/"blinkcolor2").
-+*
-+* "blinkrate" ranges between 0 and 255. When 0, blinking is disabled. 255 is
-+* the fastest blink rate and 1 is the slowest.
-+*
-+* Both "width" and "height" must be between 1 and 64; it is preferable to have
-+* "width" a multiple of 16.

-+* ioctl(fd, FBIO_EP93XX_LINE, ep93xx_line *)
-+*
-+* The line starts at ("x1","y1") and ends at ("x2","y2"). This means that
-+* when using a pattern, the two coordinates are not transitive (i.e. swapping
-+* ("x1","y1") with ("x2","y2") will not necessarily draw the exact same line,
-+* pattern-wise).
-+*
-+* "pattern" is a 2 to 16 bit pattern (since a 1 bit pattern isn't much of a
-+* pattern). The lower 16 bits define the pattern (1 being foreground, 0 being
-+* background or transparent), and bits 19-16 define the length of the pattern
-+* (as pattern length - 1). So, for example, "0xf00ff" defines a 16 bit
-+* with the first 8 pixels in the foreground color and the next 8 pixels in the
-+* background color or transparent.
-+*
-+* LINE_PRECISE is used to apply angularly corrected patterns to line. It
-+* should only be used when LINE_PATTERN is also set. The pattern will be
-+* applied along the length of the line, instead of along the length of the
-+* major axis. This may result in the loss of fine details in the pattern, and
-+* will take more time to draw the line in most cases.

-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.

-> the SDHC cards I have don't work at all, spewing tons of:
-> mmcblk0: error -38 sending status comand
-> mmcblk0: error -38 sending read/write command, response 0x4, card status 0xff04
-> end_request: I/O error, dev mmcblk0, sector 7744509
-
-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.

-Really, this is wrong, since /proc/cpuinfo should report the revision and

-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.

-This problem is easy to reproduce, just read last sector of the

-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 patch puts the EP93xx chip revision and unique ID into /proc/cpuinfo.

-Really, this is wrong, since /proc/cpuinfo should report the revision and

-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.

-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.
