Commit b8893327e9d2 (dm: serial: Put common code into separate functions)
consolidated getc() correctly, but introduced another bug to putc();
serial_stub_putc() passes sdev->priv to serial_putc_dev(), but
serial_putc_dev() uses cur_dev instead of the given argument.

The functions _serial_putc, _serial_putc_raw, _serial_puts,
_serial_getc, _serial_tstc, _serial_setbrg are defined and used
locally in each of serial_ns16550.c and serial_s3c24x0.c.
Add static directive to them and remove declarations from
include/common.h.

The platform_data definitions are generally referenced from both
drivers and board files. That is why header files defining
platform_data sturectures are placed in "include" directory,
but our top level "include" directory is already too cluttered.
Let's collect platform_data definitions under the directory
"include/dm/platform_data" like Linux gathers ones around under
"include/linux/platform_data".
This commit moves two header files:
include/serial_mxc.h -> include/dm/platform_data/serial_mxc.h
include/serial_pl01x.h -> include/dm/platform_data/serial_pl01x.h

Convert over this driver, using device tree to pass in the required
information. The peripheral is still probed, just the number of GPIO banks
and their offsets is in the device tree (previously this was a table in
the driver).

To permit information to be passed from the early U-Boot code to
board_init_f() we cannot zero the global_data in board_init_f(). Instead
zero it in the start-up code.

We have several GPIO drivers now and all are doing similar things to record
which GPIOs are reserved.
Move this logic into the uclass to make the drivers similar.
We retain the request()/free() methods since currently one driver does use
these for setting up the pin.

With these options in place it is not possible to change the serial port
using 'make menuconfig' or similar. It seems to result in duplicate
defines.
For example:
In file included from include/linux/kconfig.h:4:0,
from <command-line>:0:
include/generated/autoconf.h:20:0: note: this is the location of the previous definition
#define CONFIG_CONS_INDEX 2
^
The default option seems to be 1 anyway, in board/ti/am335x/Kconfig.
Remove the options so that we can adjust the serial port if required.

Add a separate internal helper function to get a GPIO value, so that we

duplication.
Also move gpio_get_bank() and check_gpio() down below the helper functions

The probe logic sets up the pointer to the platform data in the device
tree decode method. It should be done in the probe() method, and anyway
the device tree decode method can't be used when CONFIG_OF_CONTROL is

We have moved the busy-wait loop out of drivers and into the uclass. This
means that we must reset the watchdog when busy-waiting.
Note: some drivers may still have a busy-wait even with driver model, as
a transition mechanism. Driver model will tolerate this, and is can be
cleaned up when all users of the driver use driver model. An example is
ns16550.

At present banks must be named and it is not possible to refer to GPIOs by
number in driver model. Some boards use numbering - e.g. OMAP. It is fairly
easy to support by detecting the absense of a bank name (which starts with
a letter).
Add support for numbered GPIOs in addition to the existing bank support.

Without the private libgcc, we need a full multilib toolchain with
different libgcc or multiple toolchains to build all BE/LE and
hard-float/soft-float variants of MIPS boards. That is not feasible.
This commit allows us to build all the MIPS boards with a single
kernel.org toolchain:
https://www.kernel.org/pub/tools/crosstool/files/bin/x86_64/4.9.0/
x86_64-gcc-4.9.0-nolibc_mips-linux.tar.xz
This change sounds reasonable for most users. If necessary,
you can disable this option via "make menuconfig" or friends.

touches .config when spl/.config is updated to invoke silentoldconfig.

The private libgcc is supported only on ARM, MIPS, PowerPC, SH, x86.
Those architectures should "select" HAVE_PRIVATE_LIBGCC and
CONFIG_USE_PRIVATE_LIBGCC should depend on it.
Currently, this option is enabled on Tegra boards and x86 architecture.
Move the definition from header files to Kconfig.
