[PATCH v2 00/13] drivers: mailbox: framework creation

[Suman Anna]

Hi,

Please find below the updated patch series for mailbox framework creation.
After commit e8d3d47 (ARM: OMAP2+: Drop plat/cpu.h for omap2plus), the
cpu_is_xxx() checks for OMAP are restricted to arch/arm/mach-omap2. The
series includes 4 new patches, first patch removes these earch specific
calls of OMAP mailbox driver code (dependencies with soc.h), and the last
three patches include minor fixes in mailbox driver code. 

This series is based on v3.8-rc7 and includes the necessary updates/fixes
required for validating remoteproc on OMAP4 and tidspbridge on OMAP3. The
series is an updated version of [2], a branch created with build fixes
for [1] based on offline reviews.

Other changes include:
- adaptations to remoteproc and tidspbridge to use the new mailbox
  api, and relying on the pdata field in the mailbox_msg structure
  instead of the previous header field (addressing review comments)
- ST-Ericsson driver update
- Kconfig fixes to fix build errors and choose proper ARCH dependencies
- 3 new patches for minor fixes in mailbox driver code
- rebased to include the devinit/devexit cleanup changes
- checkpatch errors/warnings fixes

I have hosted the series at [3].

v1:
OMAP and ST-Ericsson platforms are both using mailbox to communicate
with some coprocessors.
Based on OMAP existing mailbox framework, this series proposes a
generic framework, living under drivers/mailbox.

This series:
- moves omap-mailbox framework to a newly drivers/mailbox folder
  (part of plat-omap code cleaning)
- creates API header file
- replaces "omap" prefix by "mailbox"
- opens interface and make framework independent from omap HW
- adapts existing omap1 and omap2 drivers to new changes
- creates dbx500 mailbox driver for ST-Ericsson platforms
