Hello,
This patchset 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 has been based and tested on the latest master branch as of this writing.
- Sanchayan.
