the appropriate value in Hz.
- MMC Support:
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
===========================================
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
model. Please feel free to update this file with your ideas and suggestions.
