Re SD/MMC subsystem resources

[mani]

Hi,

I also didnt get any good doc on the mmc sub system
whereas there are few things that might help
A slide which explains driver stack:-
http://www.slideshare.net/champ_yen/linux-sdmmc-driver-stack

Check JEDEC specs (open standard for MMC /eMMC)
http://www.jedec.org/sites/default/files/docs/JESD84-A441.pdf

1. Card
you can look into linux kernel directory drivers/mmc/card/
very few files and easy to understand. can map with JEDEC pdf.
Block.c , queue.c and mmc_test.c

2. Core
Generic layer - Not much to be done in this if you are writing a driver or
so.

3. Host
drivers/mmc/host/
There are few sample mmc driver file are there although
This is specific to your chip. so needed data sheet. Also JEDEC spec can
help a bit.

Hope this helps.
Thanks
Manish
