How-To connect an MMC/SD adapter/connector to your APF9328

For instructions on how to use MMC/SD on Linux, see [[MultiMediaCard]] page. 
'''SDCard, MiniSD, and Transflash/MicroSD are all the same devices but in different package shapes and are all pin compatible.''' 
On Armadeus boards, MMC are controlled in 1 bit MMC mode and SD/MiniSD/MicroSD in 4 bits SD mode.
We don't use MMC/SD in "fucking slow & error prone" SPI mode.

== Adapter board (for DevLight 1.0 or your custom board) ==
We have designed a small adapter board with a push-pull MMC/SD connector on it.
You need to connect the signals listed in the table below to the corresponding one on your DevLight board.
The WP and CD_SW signals are optional and must be connected to free i.MXL GPIOs, if used.

Remarks:
* Pin 1 (rectangular/square pad)
* WP: write protect
* CD_SW: Card Detect switch
