The MMC controller on the Intel PXA is supported. To
enable this define CONFIG_MMC. The MMC can be
accessed from the boot prompt by mapping the device
to physical memory similar to flash. Command line is
enabled with CONFIG_CMD_MMC. The MMC driver also works with
the FAT fs. This is enabled with CONFIG_CMD_FAT.

* MACRO: Fld
*
* Purpose
* The macro "Fld" encodes a bit field, given its size and its shift value
* with respect to bit 0.
*
* Note
* A more intuitive way to encode bit fields would have been to use their
* mask. However, extracting size and shift value information from a bit
* field's mask is cumbersome and might break the assembler (255-character
* line-size limit).
*
* Input
* Size Size of the bit field, in number of bits.
* Shft Shift value of the bit field with respect to bit 0.
*
* Output
* Fld Encoded bit field.

How to port a serial driver to driver model How to port a serial driver to driver model
=========================================== ===========================================
Almost all of the serial drivers have been converted as at January 2016. These
ones remain:
* serial_bfin.c
* serial_pxa.c
The deadline for this work was the end of January 2016. If no one steps
forward to convert these, at some point there may come a patch to remove them!
Here is a suggested approach for converting your serial driver over to driver Here is a suggested approach for converting your serial driver over to driver
model. Please feel free to update this file with your ideas and suggestions. model. Please feel free to update this file with your ideas and suggestions.
