The Samsung initrd for SMDK6410 is now bigger than the original initrds
that where used. Increase the command-line size and the size of the ramdisk
that it is unpacked into.
Also change the default init to /linuxrc to avoid problems with the current
SMDK ramdisk image failing to run /bin/bash.

All of the cached/uncached mapping setup is duplicated for each size, and
also misses out on the 16MB case. Rather than duplicating the same iter
code for that we just consolidate it in to a helper macro that builds an
iter for each size. The 16MB case is then trivially bolted on at the end.

During suspend, the kernel timekeeping subsystem is shut down. Before
suspend and upon resume, it uses a weak function
read_persistent_clock() to determine the amount of time that elapsed
during suspend.
This function was not implemented on OMAP, so from the timekeeping
subsystem perspective (and thus userspace as well) it appeared that no
time elapsed during suspend.
This patch uses the 32k sync timer as a the persistent clock.
NOTE: This does *NOT* fully handle wrapping of the 32k sync timer, so
more than one wrapping of the 32k sync timer during suspend may
cause problems. Also note there are not interrupts when the 32k
sync timer wraps, so something else has to be done.

Due to OMAP3 erratas 1.157, 1.185 the save of the last pad register
(ETK_D14 and ETK_D15) can fail sometimes when there is simultaneous
OCP access to the SCM register area. Fixed by writing the last
register to the save area.
Also, optimized the delay loop for the HW save to include an udelay(1),
which limits the number of unnecessary HW accesses to SCM register area

We already know the pfn for the page to be modified in make_coherent,
so let's stop recalculating it unnecessarily.
Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
update_mmu_cache() is called with a page table already mapped. We
call make_coherent(), which then calls adjust_pte() which wants to
map other page tables. This causes kmap_atomic() to BUG() because
the slot its trying to use is already taken.
Since do_adjust_pte() modifies the page tables, we are also missing
any form of locking, so we're risking corrupting the page tables.
Fix this by using pte_offset_map_nested(), and taking the pte page
table lock around do_adjust_pte().

This implements dynamic probing for the system FPGA. The system reset
controller contains a fixed magic read word in order to identify the
FPGA. This just utilizes a simple loop that scans across all of the fixed
physical areas (area 0 through area 6) to locate the FPGA.
The FPGA also contains register information detailing the area mappings
and chip select settings for all of the other blocks, so this needs to be
done before we can set up anything else.

iounmap_fixed() had a couple of bugs in it that caused it to effectively
fail at life. The total number of pages to unmap factored in the mapping
offset and aligned up to the next page boundary, which doesn't match the
ioremap_fixed() behaviour.
When ioremap_fixed() pegs a slot, the address in the mapping data already
contains the offset displacement, and the size is recorded verbatim given
that we're only interested in total number of pages required. As such, we
need to calculate the total number from the original size in the unmap
path as well.
At the same time, there was also an off-by-1 problem in the fixmap index
calculation which has also been corrected.
Previously subsequent remaps of an identical fixmap index would trigger
the pte_ERROR() in set_pte_phys():
arch/sh/mm/init.c:77: bad pte 8053ffb0(0000781003fff506).
