Allwinner SoCs provide uart0 muxed with mmc0, which can then be used
with a micro SD breakout board. On the A23, this is the only way to
use uart0.

The RTC hardware has been moved out of the timer block on sun6i/sun8i.
In addition, there are more watchdogs available.
Also note that the timer block definition is not completely accurate
for sun5i/sun7i. Various blocks are missing or have been moved out.

On later Allwinner SoCs, the watchdog hardware is by all means a
separate hardware block, with its own address range and interrupt
line.
Move the register definitions to a separate file to facilitate
supporting newer SoCs.

BOOT_TARGET_DEVICES includes MMC unconditionally. This breaks when
CONFIG_CMD_MMC is not defined. Use a secondary macro to conditionally
include it when CONFIG_MMC is enabled, as we do for CONFIG_AHCI.
This is used when we want to use uart0 from port F, which conflicts
with mmc0.

Many people are still using old linux-sunxi-3.4 kernels on sunxi devices,
adding the proper MACH_TYPE defines for this allows people to switch to
upstream u-boot, so that we can stop maintaining the linux-sunxi u-boot fork.
These machine-ids are all properly registered at:

Enable the second sdcard slot found on some boards. Note that we do not
set CONFIG_MMC_SUNXI_SLOT_EXTRA for the SPL, as having it there is not useful,
Except for on the Mele-M3 where the second sdcard is an eMMC, from which the
device can also boot, and there we want to have both in the SPL, so that
a single u-boot binary can both from both. So for the M3 we do prefix the
defconfig setting with the special "+S:" syntax so that it applies to the
SPL too.

None of the known sunxi devices actually use mmc1 routed through PH, where
as some devices do actually use mmc1 routed through PG, so change the routing
of mmc1 to PG. If in the future we encounter devices with mmc1 routed through
PH, we will need to change things to be a bit more flexible.

sunxi SOCs can boot from both mmc0 and mmc2, detect from which one we're
booting, and make that one "mmc dev 0" so that a single u-boot binary can
be used for both the onboard eMMC and for external sdcards.
When we're booting from mmc2, we make it dev 0 because that is where the SPL
will load the tertiary payload (the actual u-boot binary in our case) from,
see: common/spl/spl_mmc.c, which has dev 0 hardcoded everywhere.

Note we also drop the SPL check for initializing the 2nd mmc slot, the SPL
check is not necessary with Kconfig, because only options explicitly marked
as also being for the SPL get set during SPL builds.

The A31 has a new module called PRCM, or Power, Reset Control Module.
This module controls clocks and resets for RTC block modules, and also
PLL biasing in the main clock module.
This patch adds the register definitions, and also enables the clocks
and resets for the RTC block PIO (pin controller) and P2WI (push-pull
2 wire interface) which is used to talk to the PMIC.

This commit converts UniPhier on-chip serial driver to driver model.
Since UniPhier SoCs do not have Device Tree support, some board files
should be added under arch/arm/cpu/armv7/uniphier/ph1-*/ directories.
(Device Tree support for UniPhier platform is still under way.)
Now the base address and master clock frequency are passed from
platform data, so CONFIG_SYS_UNIPHIER_SERIAL_BASE* and
CONFIG_SYS_UNIPHIER_UART_CLK should be removed.
Tested on UniPhier PH1-LD4 ref board.

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

This makes use of the existing device tree node to use driver model
for the serial console.

Add more information so that U-Boot can find the address of the serial port.
Also fix the reg-shift value.

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).

This code doesn't follow the normal approach of having its arch-specific
definitions in an arch-specific directory. Add a new arch-specific file
and make use of it.

Add support for this by reserving a block of memory below global_data.

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.

This code generates warnings with recent gcc versions. We really don't need
the clobber specification, so just drop it.
