Hi,
I have just tested kernel 2.6.24-rc1 with SD/MMC through SPI bus on the
AT91SAM9261EK board (SPI NPCS3) and noted that the SD card was detected and
info were noted under "/sys/bus/mmc" directory.
However, no device, such as mmcblk0p1, was assigned at all.
I have 2 questions with regards to SD/MMC over SPI.
1) In the code, I have commented out all other SPI devices on SPI0 bus
except for the SD card at spi0.3. However, I got an error "can't share SPI
bus". Anyone can advise what is the reason behind this error ?
(In order to proceed with my test below, I temporary got over this issue by
commenting out the check that gives this error.)
2) The kernel 2.6.24-rc1 boots up and detected the SD card with the console
output "new SD card on SPI". However, no device name, such as mmcblk0p1,
were allocated. In addition, I noted the following messages before the
sentence "mmc0: new SD card on SPI".

****** end of extract ***********
(I have attached a console debug output, including dmesg output, as well)
FYI, I am using a blank 16MB SD card with FAT filesystem.
Appreciate any advices/help given.
Lastly, I would like to know if the SD/MMC over SPI can be shared with other
SPI devices, such as touchscreen controller ADS7843 (purposely left out in
the current code) ?
Thanks in advance.
