6dbfda81c0 sun6i: Poke magic sram controller register to avoid cache issues
Without this the cache will only work in write-through mode, and as soon as
it is put in write-back mode things break.

ed41e62f51 sunxi: Use CONFIG_MACH_SUN?I from Kconfig instead of CONFIG_SUN?I
Mostly automatic with:
    sed -i -e 's/CONFIG_\(SUN[45678]I\)/CONFIG_MACH_\1/g' $(git grep -l CONFIG_SUN[45678]I)
followed by removing the relevant #defines from include/configs/sun?i.h by
hand.

c757a50bd1 ARM: sunxi: Add support for using R_UART as console
The A23 only has UART0 muxed with MMC0. Some of the boards we
encountered expose R_UART as a set of pads.

Add support for R_UART so we can have a console while using mmc.

8ebe4f4292 ARM: sunxi: Add basic A23 support
The basic blocks of the A23 are similar to the A31 (sun6i). Re-use
sun6i code for initial clock, gpio, and uart setup.

There is no SPL support for A23, as we do not have any documentation
or sample code for DRAM initialization.

ff2b47f6a9 ARM: sunxi: Add support for uart0 on port F (mmc0)
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.

78c396a113 ARM: sunxi: Fix reset command on sun6i/sun8i
The watchdog on sun6i/sun8i has a different layout.

Add the new layout and fix up the setup functions so that reset works.

6620377e4b sunxi: Add i2c support
Add support for the i2c controller found on all Allwinner sunxi SoCs,
this is the same controller as found on the Marvell orion5x and kirkwood
SoC families, with a slightly different register layout, so this patch uses
the existing mvtwsi code.

f84269c5c0 sunxi: Add sun5i support
Add support for the Allwinner A13 and A10s SoCs also know as the Allwinner
sun5i family, and the A13-OLinuXinoM A13 based and r7-tv-dongle A10s based
boards.

The only differences compared to the already supported sun4i and sun7i
families are all in the DRAM controller initialization:

-Different hcpr values
-Different MBUS settings
-Some other small initialization changes

cba69eeeaa sunxi: add sun7i cpu, board and start of day support
This patch adds generic board, start of day and basic build system support for
the Allwinner A20 (sun7i) processor. This code will not been compiled until the
build is hooked up in a later patch. It has been split out to keep the patches
manageable.
