Much thanks for the patches! Though, I still have some troubles with getting MMC(SD)-over-SPI to work. I'm using slightly patched spi_mpc83xx.c driver + these four mmc patches. spi_mpc83xx.c tested only in loopback mode and using oscilloscope. It _seem_ to work fine, but as I didn't tested it on real hardware (other than MMC/SD), I can't say if it's fault of spi_mpc83xx or mmc_spi. David, can you see anything helpful in these debug messages? - - - - mmc_spi spi1.0: ASSUMING unshared SPI bus! mmc_spi spi1.0: ASSUMING 3.2-3.4 V slot power mmc0: clock 0Hz busmode 0 powermode 0 cs 0 Vdd 0 width 0 timing 0 mmc_spi spi1.0: SD/MMC host mmc0, no DMA, no WP, no poweroff mmc0: clock 0Hz busmode 2 powermode 1 cs 1 Vdd 21 width 0 timing 0 mmc_spi spi1.0: mmc_spi: power up (21) mmc0: clock 400000Hz busmode 2 powermode 2 cs 1 Vdd 21 width 0 timing 0 mmc_spi spi1.0: mmc_spi: power on (21) mmc_spi spi1.0: mmc_spi: clock to 400000 Hz, 0 mmc0: starting CMD0 arg 00000000 flags 000000c0 mmc_spi spi1.0: mmc_spi: CMD0, MMC_SPI_R1 mmc0: req done (CMD0): 0/0/0: 00000001 00000000 00000000 00000000 mmc0: starting CMD8 arg 000001aa flags 000002f5 mmc_spi spi1.0: mmc_spi: CMD8, MMC_SPI_R3/R7 mmc_spi spi1.0: ...
