-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

-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,

-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.
