Suman Anna 4499ce4293 omap: mailbox: correct OMAP4 SIDLEMODE logic
OMAP4 mailbox has a different MAILBOX_SYSCONFIG register.
There is now no AutoIdle. The SIDLEMODE bits have been
right-shifted by 1 bit and now occupy bits 2 & 3.

Suman Anna a6a6022871 omap: mailbox: correct OMAP4 reset logic
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
previous generations.

Tobias Klauser 6d13524209 omap: Use resource_size
Use the resource_size function instead of manually calculating the
resource size. This reduces the chance of introducing off-by-one errors
and actually fixes one in mailbox.c.

Tony Lindgren ce491cf854 omap: headers: Move remaining headers from include/mach to include/plat
Move the remaining headers under plat-omap/include/mach
to plat-omap/include/plat. Also search and replace the
files using these headers to include using the right path.

This was done with:

#!/bin/bash
mach_dir_old="arch/arm/plat-omap/include/mach"
plat_dir_new="arch/arm/plat-omap/include/plat"
headers=$(cd $mach_dir_old && ls *.h)
omap_dirs="arch/arm/*omap*/ \
drivers/video/omap \
sound/soc/omap"
other_files="drivers/leds/leds-ams-delta.c \
drivers/mfd/menelaus.c \
drivers/mfd/twl4030-core.c \
drivers/mtd/nand/ams-delta.c"

for header in $headers; do
	old="#include <mach\/$header"
	new="#include <plat\/$header"
	for dir in $omap_dirs; do
		find $dir -type f -name \*.[chS] | \
			xargs sed -i "s/$old/$new/"
	done
	find drivers/ -type f -name \*omap*.[chS] | \
		xargs sed -i "s/$old/$new/"
	for file in $other_files; do
		sed -i "s/$old/$new/" $file
	done
done

for header in $(ls $mach_dir_old/*.h); do
	git mv $header $plat_dir_new/
done

Hiroshi DOYU 8828880d09 omap: mailbox: Flush posted write when acking mailbox irq
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
