keventd_wq is a shared work-queue, and should not be used when we
need fast deterministic response.  Instead mailbox driver should
use it's own private work-queue, with it's own thread, to ensure
that handling of RX interrupts are not delayed by other drivers.

The tasklet is still used for transmission of mbox messages.

OMAP4 mailbox has a different register set. There is
no MAILBOX_SYSSTATUS register. The reset is indicated
with the SOFTRESET bit of the MAILBOX_SYSCONFIG register
itself. This bit should read 0 for a successful Reset.
Also, the SOFTRESET bit occupies bit0 and not bit1 as with

These files are generated along with the HWMOD and will eventually be

omap_hwmod / omap_device.

The dma-44xx.h and irqs-44xx.h file should be in

still share these defines and hence currently placed in plat-omap/include/plat/

This patch is addition to the already merged commit on non-empty
uart fifo read abort. "ce13d471"

OMAP3630 and OMAP4430 UART IP blocks have a restriction on TX FIFO
too. If you try to write to the tx fifo when it is full, the system aborts.

More details on this thread are here:
http://www.mail-archive.com/linux-omap@vger.kernel.org/msg19447.html

This can be easily reproducible by not suppressing interconnect errors or
long duration testing where continuous prints over console from multiple
threads. This patch is addressing the issue by ensuring that write is
not issued while fifo is full. A timeout is added to avoid any hang
on fifo-full for 10 mS which is unlikely case.

Patch is validated on OMAP3630 and OMAP4 SDP.

V2 version removed the additional 1 uS on every TX as per
Tony's suggestion
