This also removes the mach/s3c2400 version which was probably never used
due to the fact that we have this line in arch/arm/Makefile:

machine-$(CONFIG_ARCH_S3C2410)          := s3c2410 s3c2400 [...]

This is later used to construct the search path for:

The compiler would be looking into mach-s3c2410 and picking up this
version first.  Any config that was actually expecting the mach-s3c2400
version was therefore producing a broken kernel binary.  Not relying on
any of them anymore would fix that issue.

When the CONFIG_NO_MACH_MEMORY_H symbol is selected by a particular
machine class, the machine specific memory.h include file is no longer
used and can be removed.  In that case the equivalent information can
be obtained dynamically at runtime by enabling CONFIG_ARM_PATCH_PHYS_VIRT
or by specifying the physical memory address at kernel configuration time.

If/when all instances of mach/memory.h are removed then this symbol could
be removed.

This achieves two goals:

1) Get rid of davinci_uart_v2p() and davinci_uart_p2v() which were the
   last users of PLAT_PHYS_OFFSET.

2) Remove the probing of the M bit in the CP15 control reg and make
   the access to the .data variables completely position independent.

This achieves two goals:

   of PLAT_PHYS_OFFSET.

2) Remove the probing of the M bit in the CP15 control reg and make
   the access to the .data variables completely position independent.

There is a catch though: the busyuart macro needs to know where the LSR
register is which might be at a different offset depending on the hardware.
Given that this macro is given only two registers and that one of them
must be preserved, the trick is to always pass the LSR register address
around, and deduce the base address for the THR register by masking out
the LSR offset in senduart instead.

Some platforms (like OMAP not to name it) are doing rather complicated
hacks just to determine the base UART address to use.  Let's give their
addruart macro some slack by providing an extra work register which will
allow for much needed cleanups.

This is basically a no-op as this commit is only adding the extra argument
to the macro but no one is using it yet.

  Restrict DMA-able region to workaround silicon limitation.
  The limitation restricts buffers available for DMA to SD/MMC
  hardware to be below 256MB.
