According to the PPC reference implementation the udelay() function is
responsible for resetting the watchdog timer as frequently as needed.
Most other architectures do not meet that requirement, so long-running
operations might result in a watchdog reset.
This patch adds a generic udelay() function which takes care of
resetting the watchdog before calling an architecture-specific
__udelay().

Ported over the more efficient linux crc32() function.
A quick comparsion on ppc:
After changing the old crc32 to do 4 bytes in the
inner loop to be able to compare with new version one can note:
- old inner loop has 61 insn, new has 19 insn.
- new crc32 does one 32 bit load of data to crc while
the old does four 8 bits loads.
- size is bit bigger for the new crc32:
1392(old) 1416(new) of text. The is because the new version
shares code with crc32_no_comp() instead of duplicating code.
- about 33% faster on ppc:
New > crc 0 0xfffffff -> 39 secs
Old > crc 0 0xfffffff -> 60 secs

Currently, some of the tools instead set CC to be HOSTCC in order to re-use
some pattern rules -- but this fails when the user overrides CC on the make
command line. Also, the HOSTCFLAGS in tools/Makefile are currently not
being used because config.mk overwrites them.
This patch adds static pattern rules for files that have been requested to
be built with the native compiler using $(HOSTSRCS) and $(HOSTOBJS), and
converts the tools to use them.
It restores easylogo to using the host compiler, which was broken by commit
38d299c2db (if this was an intentional change,
please let me know -- but it seems to be a build tool).
It restores -pedantic and the special flags for darwin and cygwin that were
requested in tools/makefile (but keeps the flags added by config.mk) --
hopefully someone can test this on those platforms. It no longer
conditionalizes -pedantic on not being darwin; it wasn't clear that that was
intentional, and unless there's a real problem it's just inviting people to
contribute non-pedantic patches to those files (I'm not a fan of -pedantic
personally, but if it's on for one platform it should be on for all).
HOST_LDFLAGS is renamed HOSTLDFLAGS for consistency with the previous
HOST_CFLAGS to HOSTCFLAGS rename. A new HOSTCFLAGS_NOPED is made available
for those files which currently cannot be built with -pedantic, and replaces
the old FIT_CFLAGS.
imls now uses the cross compiler properly, rather than by trying to
reconstruct CC using the typoed $(CROSS_COMPILER).
envcrc.c is now dependency-processed unconditionally -- previously it would
be built without being on (HOST)SRCS if CONFIG_ENV_IS_EMBEDDED was not
selected.

The current jump table init fails to initialize a bunch of exported
symbols (forceenv/do_reset/etc...). Rather than fix just these few
missing pieces, rewrite the code to utilize the existing list of
exported symbols -- _exports.h. Since every exported symbol has to
be listed in this header, it makes sense to use it so that we only
ever have one list that needs to be updated and things can't fall
out of sync again.

When the board is booted without serial cable attached (which
is how most of them will be used) UART RX is left floating and
sometimes picks noise, which interrupts countdown and enters
U-Boot prompt instead of booting the kernel.
Fix this by setting up internal pullup on UART RX pin. This
does not prevent serial from working as the internal pullup
is weak.

Cleans up the s3c24x0 header files:
s4c24x0.h: removes the use of 'volatile' from the S3C24X0_REG8,
S3C24X0_REG16 and S3C24X0_REG32 register typedef's. Registers are always
accessed using the IO accessor functions which cast the register address
as 'volatile' anyway so it isn't required here.

This patch moves the s3c24x0 header files from include/ to
include/asm-arm/arch-s3c24x0/.
checkpatch.pl showed 2 errors and 3 warnings. The 2 errors were both due
to a non-UTF8 character in David M?ller's name:
ERROR: Invalid UTF-8, patch and commit message should be encoded in UTF-8
#489: FILE: include/asm-arm/arch-s3c24x0/s3c2410.h:3:
+ * David M?ller ELSOFT AG Switzerland. d.mueller@elsoft.ch
As David's name correctly contains a non-UTF8 character I haven't fixed
these errors.
The 3 warnings were all because of the use of 'volatile' in s3c24x0.h:
WARNING: Use of volatile is usually wrong: see Documentation/volatile-considered-harmful.txt
#673: FILE: include/asm-arm/arch-s3c24x0/s3c24x0.h:35:
+typedef volatile u8 S3C24X0_REG8;
+typedef volatile u16 S3C24X0_REG16;
+typedef volatile u32 S3C24X0_REG32;
I'll fix these errors in another patch.
Tested by running MAKEALL for ARM8 targets and ensuring there were no new
errors or warnings.

The SheevaPlug DevKit is shipped with 4x8 by 1Gb DDR devices in
two banks for a total of 512MB of RAM. Based on this configuration
the existing values for SDRAM address control register are incorrect
and result in random kernel oops as memory is incorrectly accessed
(while for example extracting a large tarball such as a rootfs).
Based on the hardware configuration along with the supporting
documentation from Marvell these are the correct values, as
well this change mimics values previously used in Marvell's own
u-boot git tree for the SheevaPlug.
Other variants of the hardware such as the PogoPlug and TonidoPlug
may have different memory configurations but to properly support
those additional board directories should be maintained or a better
system to support other kwb*.cfg is needed.
