Otherwise more complicated uart configuration won't be possible.
We can use r1 for tmp register for both head.S and debug.S.
NOTE: This patch depends on another patch to add the the tmp register
into all debug-macro.S files. That can be done with:
$ sed -i -e "s/addruart,rx|addruart, rx/addruart, rx, tmp/"
arch/arm/*/include/*/debug-macro.S

S5PC1xx Samsung SOC series has very similar frame buffer hardware, so a lot
of the code can be shared. Moved s3c64xx-specific s3c-fb register
definitions from mach-s3c6400 to common platform directory as regs-fb-v4.h.
The new v4 file will be common for S3C6400, S3C6410, S5PC100 and possibly
others. Some s3c64xx series specific defines (palette handling) were left
in s3c-6400/mach/regs-fb.h, because it is handled differently in S5PC1xx
series.

The S3C64XX DMA implementation will work a lot better with the ability
to enqueue circular buffers as the hardware can do it's own linked-list
management.
Add a function s3c_dma_has_circular() to show that the system can do this
and a flag for the channel.
Update the s3c24xx/s3c64xx I2S DMA code to deal with this.

OMAP wishes to pass state to the boot loader upon reboot in order to
instruct it whether to wait for USB-based reflashing or not. There is
already a facility to do this via the reboot() syscall, except we ignore
the string passed to machine_restart().
This patch fixes things to pass this string to arch_reset(). This means
that we keep the reboot mode limited to telling the kernel _how_ to
perform the reboot which should be independent of what we request the
boot loader to do.
