This patch adds FDT support to the serial s5p driver.
At present disabling the serial console (from the device tree) crashes
U-Boot. Add checks for this case, so that execution can continue without
a serial console.
It also enables the serial_s5p driver recognize the silent_console option.

The omap2420H4 was the only mainline omap24xx board. Prior to being
fixed by Jon Hunter in time for v2013.04 it had been functionally broken
for a very long time. Remove this board as there's not been interest in
it in U-Boot for quite a long time.

This patch enables the uart tx/rx fifo. Now that fifo is enabled,
the uart read/write functions are modfied to check the UFSTAT register
for fifo status instead of UTRSTAT (as required with fifo's enabled).
Tested by booting linux kernel. Before enabling tx/rx fifo
"Uncompressing linux" message is garbled and after enabling it is proper.

Flush UART3 xmit on enable if TEMT is broken
On some OMAP3 devices when UART3 is configured for boot mode before SPL starts
only THRE bit is set. We have to empty the transmitter before initialization
starts. This patch avoids the use of CONFIG_SYS_NS16550_BROKEN_TEMT.

'bool' is defined in random places. This patch consolidates them into a
single header file include/linux/types.h, using stdbool.h introduced in C99.
All other #define, typedef and enum are removed. They are all consistent with
true = 1, false = 0.
Replace FALSE, False with false. Replace TRUE, True with true.

Implements the tstc() interface for the serial driver. Multiplexing

Some platforms (e.g. IGEPv2 board) has a broken ns16550 UART that
does not set the TEMT bit when the transmitter is empty in SPL.
This makes U-Boot to hang while waiting for TEMT to be set.
Add a new option to avoid this:
CONFIG_SYS_NS16550_BROKEN_TEMT
16550 UART set the Transmitter Empty (TEMT) Bit when all output
has finished and the transmitter is totally empty. U-Boot waits
for this bit to be set to initialize the serial console. On some
broken platforms this bit is not set in SPL making U-Boot to
hang while waiting for TEMT. Define this option to avoid it.

On kzm9g board (rmobile SoC), autoboot fails if serial console cable is not
connected. When serial cable is not connected, serial error occurs and
some garbage comes in data register.
sh_serial_tstc() in serial_sh.c does not check error status and misunderstand
there is some input data. It is the reason that autoboot fails.
This patch adds checking error status in sh_serial_tstc().
This patch is based on v2013.01-rc1 tag of u-boot master git.

CONFIG_NS16550_MIN_FUNCTIONS is used by small SPLs to gain access to basic
ns16550 output code without pulling in things not needed by the SPL.
This previously only worked with non-MULTI configs. Recently MULTI was
made mandatory, and MIN_FUNCTIONS fails like this:
drivers/serial/libserial.o: In function `calc_divisor.clone.0':
serial_ns16550.c:(.text.calc_divisor.clone.0+0x24): undefined reference to `get_bus_freq'

make[1]: *** [/tmp/u-boot/spl/u-boot-spl] Error 1
make: *** [/tmp/u-boot/spl/u-boot-spl.bin] Error 2
With MIN_FUNCTIONS we don't need anything from this file, so don't build
it. The conditional needs to be in the file itself rather than the
makefile, because the config symbols are only imported to the makefiles
once, not separately for the SPL phase of the build.

u-boot's byteorder headers did not contain endianness attributions
for use with sparse, causing a lot of false positives. Import the
kernel's latest definitions, and enable them by including compiler.h
and types.h. They come with 'const' added for some swab functions, so
fix those up, too:
include/linux/byteorder/big_endian.h:46:2: warning: passing argument 1 of '__swab64p' discards 'const' qualifier from pointer target type [enabled by default]
Also, note: u-boot's historic __BYTE_ORDER definition has been
preserved (for the time being at least).
We also remove ad-hoc barrier() definitions, since we're including
compiler.h in files that hadn't in the past:
macb.c:54:0: warning: "barrier" redefined [enabled by default]
In addition, including compiler.h in byteorder changes the 'noinline'
definition to expand to __attribute__((noinline)). This fixes
arch/powerpc/lib/bootm.c:
bootm.c:329:16: error: attribute '__attribute__': unknown attribute
bootm.c:329:16: error: expected ')' before '__attribute__'
bootm.c:329:25: error: expected identifier or '(' before ')' token
powerpc sparse builds yield:
include/common.h:356:22: error: marked inline, but without a definition
the unknown-reason inlining without a definition is considered obsolete
given it was part of the 2002 initial commit, and no arm version was
'fixed.'
also fixed:
