[PATCH 01/12] omap: Fix compile for arch/arm/mach-omap2

[Tony Lindgren]

Patch 941132606c7611246d2034cb7b01f9270c2d1ede split IO_ADDRESS
into OMAP1_IO_ADDRESS and OMAP2_IO_ADDRESS except for the omap4
code to avoid merge conflicts with the omap4 code that was queued
earlier.

[PATCH 02/12] omap: Fix mcspi compile for 2420

[Tony Lindgren]

Commit 7869c0b9ed44404bbc675ef76f8ccb3be5496f39 added support for
additional McSPI ports. Unfortunately that broke compile for 2420.

[PATCH 06/12] omap: mailbox: Flush posted write when acking mailbox irq

[Tony Lindgren]

From: Hiroshi DOYU <Hiroshi.DOYU@nokia.com>

The only way to flush posted write to L4 bus is to do a read back
of the same register right after the write.

This seems to be mostly needed in interrupt handlers to avoid
causing spurious interrupts.

The earlier fix has been to mark the L4 bus as strongly ordered
memory, which solves the problem, but causes performance penalties.

Similar to the fix, 03803a71041e3bc3c077f4e7b92f6ceaa9426df3

[PATCH 08/12] omap: Fix wrong jtag_id for 850

[Tony Lindgren]

From: Angelo Arrifano <miknix@gmail.com>

Original message:
The previous value of the jtag_id was set for the omap730.  For the
omap850, this value is different, and this was causing
autodetection to fail.

[PATCH 11/12] omap: Fix MMC gpio_wp for BeagleBoard C2 and above

[Tony Lindgren]

From: Jarkko Nikula <jhnikula@gmail.com>

Earlier BeagleBoards were using pad AH8 muxed to GPIO29 for MMC write-protect.
However, this signal has been changed to pad AG9 in board revision C2.

Fix this by adding mux configuration for pad AG9, runtime check for board
revisions and set the gpio number and pad muxing accordingly.

Use the resource_size function instead of manually calculating the
resource size. This reduces the chance of introducing off-by-one-errors.

Just curious, is it really necessary to read back the _same_ register?
Would reading back any L4 bus-related register be sufficient?

It seems that reading back any register in the same device will do it.
