[U-Boot] [PATCH v2 0/6] Add support for Colibri Vybrid Modules

[Sanchayan Maity]

Hello,

This is the second version of the patchset which adds support for the 
Toradex Colibri Vybrid VF50 and VF61 modules. Boot up has been tested 
using the serial loader over UART.

First patch in the series refactors the DDR related code for use by both
the tower board and colibri modules. It also introduces a DDR3 based
JEDEC timing structure.

Second third and fourth patch in this series are improvement patches
related to RTC, SoC/CPU detection and caches.

Fifth patch introduces USB support for Vybrid modules. Much of the code
is similar to the ehci-mx6 driver. One open question here would be is
there a better way to take care of this similarity and perhaps share the
code base among the two drivers? Both host and client modes are working
and DFU has also been tested. Currently, we restrict the ports to be in
one of host and client mode.

Sixth patch adds the actual support for the Colibri modules.

Comments and feedback are most welcome.

The patchset is based and tested on the latest master branch as of
this writing.

Discussion on the version 1 of the patchset can be found at the below

Changes since v1:
- Rework the USB driver to use register offsets using the regular 
struct {} method
- Some cleanups and fixes in the sixth patch for the colibri_vf.h file 
which takes care of environment variables in uboot
- Purge some useless defines in the fifth and sixth patch which were 
related to USB.
