[meta-fsl-arm PATCH V2 0/3] Add MCC support for Freescale Vybrid platforms

[meta-fsl-arm PATCH V2 0/3] Add MCC support for Freescale Vybrid platforms

[Andy Voltz]

Freescale Vybrid platforms use an MCC (Multi-core-communication) protocol to
communicate between Linux running on the A5 and MQX images running on the M4.

This series adds the kernel support, as well as userspace packages necessary
to run an MQX image and communicate over MCC.

These package versions are compatible with MCC version 1 API which is
implemented in MQX 4.0.1 series.

For more information about this API and packages, visit:
https://linuxlink.timesys.com/docs/wiki/engineering/userguide_vybrid_mcc

[meta-fsl-arm PATCH 1/3] kernel-module-mcc: Add package

[Andy Voltz]

kernel-module-mcc is a kernel module for Freescale Vybrid platforms.

This module is used for communication and synchronization between
MQX applications (running on the M4) and Linux (on A5)

[meta-fsl-arm PATCH 2/3] libmcc: Add package

[Andy Voltz]

libmcc is a userspace library which can be used in Linux applications on
Freescale Vybrid Platforms. This library interfaces with the kernel-module-mcc
to pass information to MQX running on the M4.

Andy, I pushed this serie to master-next and did minor changes in the
commit logs to avoid repeating the recipe name in short and long
commit logs. Please take a look in the master-next and let me know if
they're good for you.
