Hello, I have an embedded system with an on-board processor powerpc MPC5200B
and Linux kernel 2.6.22,
I must turn over to MMC SPI on the PSC6.

The MMC over SPI is connected to MPC5200b, here's how:

MPC5200B
---------------- | |------------------
PSC1_2 |--->------------Chip_Select (out)---------| | |
| | SD CARD
ETH_17 |---<------------IRQ (in)------------------| MMC over SPI
| |
| |
PSC6_0 |---<------------SPI_RXD (in)------------|
| |
| |
PSC6_2 |--->------------SPI_TXD (out)-----------|
| |
| |
PSC6_3 |--->------------SPI_CLK (out)-----------|
| |------------------
----------------

Now on the menuconfig enabling these options:

$ make ARCH=powerpc CROSS_COMPILE=powerpc-linux-gnu- menuconfig

Platform support --->
[*] MPC5200 (L25R) bugfix support
[*] Freescale Lite5200 Eval Board

Device Drivers ---> SPI Support --->
[*] SPI support
<*> Freescale MPC52xx PSC SPI controller

Now I have applied those patch:
http://www.mail-archive.com/spi-devel-general@xxxxxxxxxxxxxxxxxxxxx/msg00150.html

Now on the menuconfig enabling these options:

$ make ARCH=powerpc CROSS_COMPILE=powerpc-linux-gnu- menuconfig

Device Drivers ---> MMC/SD card support --->
[*] MMC debugging
<*> MMC block device driver
<*> MMC host test driver
<*> MMC/SD over SPI

Is correct applied those patch and enable those options into menuconfig?

thanks Fabio
