Move the GPIO and GPIO configuration headers into arch/arm/plat-samsung
as they are common to all the Samsung SoCs.

Move the gpio.c code containing the core gpiolib and GPIO support to
plat-samsung from plat-s3c as it is used by all current Samsung SoCs.
Note, we didn't move this to gpiolib.c as it contains code that is not
strictly for gpiolib support and the 4bit code is already called gpiolib.c
so make the change easier by not renaming both files in one go.

This patch moves GPIO common functions (from plat-s3c64xx) into plat-samsung.
and adds the config option to build the plat-samsung/gpiolib for Samsung SoCs.

Just use the standard ide_timing_compute() helper to calculate
PIO timings. This fixes many issues with the open-coded version
like using 16-bit timings when 8-bit ones should be used or not
accounting for the enhanced cycle time specified by the device.

This patch modifies s3c24xx_serial_initconsole function to accept multiple
platform UART information structures. This is required on platforms that have
differences among the instances of UART ports. As an example, the FIFO sizes
could be different for each UART instance and hence multiple platform UART
information structures would be needed.
This patch also modifies the s3c24xx_console_init macro since it wraps the
call to the s3c24xx_serial_initconsole function.

Add a s3c24xx_mci_set_platdata() call for all the machine files that have

the other devices with __initdata and a specific call to ensure the right

sh64 on the other hand provides both direct broken out syscalls as well
as socketcall access. As there are binaries that use both socketcall has
to stay around. The current ABI prefers direct syscalls.
It was pointed out that when sys_recvmmsg was added in, sys_accept4 was
overlooked. This takes care of wiring it up.

sh32 at the moment only uses sys_socketcall to reach these, so unwire
recvmmsg for now. While we're at it, add it to the ignore list, as per

Presently the build bails with the following:
CC arch/sh/mm/alignment.o
cc1: warnings being treated as errors
arch/sh/mm/alignment.c: In function 'unaligned_fixups_notify':
arch/sh/mm/alignment.c:69: warning: cast to pointer from integer of different size
arch/sh/mm/alignment.c:74: warning: cast to pointer from integer of different size
make[2]: *** [arch/sh/mm/alignment.o] Error 1
This is due to the fact that regs->pc is always 64-bit, while the pointer size
depends on the ABI. Wrapping through instruction_pointer() takes care of the
appropriate casting for both configurations.

Presently this is duplicated between tlb-sh4 and tlb-pteaex. Split the
helpers out in to a generic tlb-urb that can be used by any parts
equipped with MMUCR.URB.
At the same time, move the SH-5 code out-of-line, as we require single
global state for DTLB entry wiring.

This provides a dummy value for legacy parts which permits the entry
wiring to be open-coded. The compiler takes care of optimizing the entry

Presently ioremap_prot() uses an unsigned long to pass the pgprot value
around. This results in the upper half of the pgprot being chomped when
using 64-bit pgprots on a 32-bit ABI (X2TLB and SH-5).
As the only users of ioremap_prot() are presently legacy parts, this
doesn't cause too much of an issue. In the future when the interface is
converted to use pgprot_t directly this can be re-enabled for the other
parts, too.

This is already taken care of in the top-level ioremap, and now that
no one should be calling ioremap_fixed() directly we can simply throw the
mapping displacement in as an additional argument.

Presently 'flags' gets passed around a lot between the various ioremap
helpers and implementations, which is only 32-bits. In the X2TLB case
we use 64-bit pgprots which presently results in the upper 32bits being
chopped off (which handily include our read/write/exec permissions).
As such, we convert everything internally to using pgprot_t directly and
simply convert over with pgprot_val() where needed. With this in place,
transparent fixmap utilization for early ioremap works as expected.
