On the DRA72x (J6Eco) EVM one PMIC SMPS is powering three SoC
core rails. This concept of using one SMPS to supply multiple
core domains (in various, although limited combinations, per
primary device use case) has now become common and is used by
many customer J6/J6Eco designs; it is supported by a number of
corresponding PMIC OTP versions.
This patch implements correct operation of the core voltages
scaling routine by ensuring that each SMPS that is supplying
more than one domain shall be written only once, and with the
highest voltage of those fused in the SoC (or of those defined
in the corresponding header if fuse read is disabled or fails)
for the power rails belonging to the group.

The DDR PHY training function, ddrphy_prepare_training() would not
work if compiled with GCC 4.9.
The struct ddrphy (arch/arm/include/asm/arch-uniphier/ddrphy-regs.h)
is specified with __packed because it represents a hardware register
mapping, but it turned out to cause a problem on GCC 4.9.
If -mno-unaligned-access is specified (yes, it is in
arch/arm/cpu/armv7/config.mk), GCC 4.9 is aware of the
__attribute__((packed)) and generates extra instructions to perform
the memory access in a way that does not cause unaligned access.
(Actually it is not need here because the register base, the first
argument of the ddrphy_prepare_training(), is always given with a
4-byte aligned address.)
Anyway, as a result, readl() / writel() is divided into byte-wise
accesses. The problem is that this hardware only accepts 4-byte
register access. Byte-wise accesses lead to unexpected behavior.
There are some options to avoid this problem.
[1] Remove -mno-unaligned-access
[2] Add __aligned(4) along with __packed to struct ddrphy
[3] Remove __packed from struct ddrphy
[1] solves the problem for ARMv7, but it does not for pre-ARMv6 and
ARMv6-M architectures where -mno-unaligned-access is default.
So, [1] does not seem reasonable in terms of code portability.
Both [2] and [3] work well, but [2] seems too much. All the members
of struct ddrphy have the u32 type. No padding would be inserted
even if __packed is dropped.

Testing has shown that on sun4i the display backend engine does not have
deep enough fifo-s causing flickering / tearing in full-hd mode due to
fifo underruns. On sun4i use the display frontend engine to do the dma from
memory, as the frontend does have deep enough fifo-s.
As added advantage of this is that it results in much better memory bandwidth
as it reduces the amount of dram bank switches, for more details see:

While working on adding more boards I noticed that we lack a config for
the 512M cubieboard, and that some of the new boards which I want to add also
have 512M and 1G variants, rather then adding 2 defconfig's for all of these,
lets switch the exising boards which have both a 512M and 1024M variant over
to the sun4i dram autoconfig code.
This also drops the foo_RAMSIZE_defconfig variants of boards where we currently
have 2 separate configs already.
Note:
1) The newly introduced CONFIG_DRAM_EMR1 kconfig value is not used with
a value other then its default for now, but we need this to be configurable
to support some new boards with auto dram config.
2) We always set all CONFIG_DRAM_foo values in defconfigs, even if they match
the defaults, this is done to make it more clear what values are used for a
certain board.
This has been tested on a Mele A1000, Mini-X and a Cubieboard, all 1G
variants, the dram autoconfig code has also been tested on a 512M mk802
(a defconfig for the mk802 is added in a later patch).

While running some tests with an Olinuxino-A13-Micro + a 7" Olimex LCD module
I noticed that the screen flickered. This is caused by the lcd display clk
phase reg value being set to 0, where it should be 1 in this setup.
This commit adds a Kconfig option for the lcd display clk phase, so that we
can set it per board. This defaults to 1, because looking at all the fex
files in sunxi-boards, that is by far the most used value.
This commit updated the Ippo and MSI Primo73 tablet defconfigs to override the
default of 1 with 0, as that is the correct value for those tablets, this
keeps the register settings the same as before this commit.
The Olinuxino-A13 defconfigs are not updated, changing the register setting

2 recent sunxi changes have removed the usage of lowlevel_init by moving some
code around and then setting CONFIG_SKIP_LOWLEVEL_INIT.
This is problematic for 2 reasons:
1) It does not just stop s_init from being called, it also stops
cpu_init_cp15 from getting called, which is undesirable.
2) We want u-boot.bin to be usable standalone, without SPL, some people e.g.
use an upstream u-boot.bin together with Allwinner's boot0 loader. So
u-boot.bin must (re)initialize the gpios, timer, etc.
This commit restores the lowlevel_init / s_init usage, while keeping the
changes to no longer use the global-data (gd) struct in the SPL.

related registers tuples from the imximage.cfg file. As all this
is done in the SPL at run-time.

The current sunxi implementation uses gdata, which is going away. It also
sets up DRAM before board_init_f() in SPL.
There is really no reason to do much in s_init() since board_init_f() is
called immediately afterwards. The only change is that we need our own
implementation of board_init_f() which sets up DRAM before the BSS (which
is in DRAM) is cleared.
The s_init() code runs once for SPL and again for U-Boot proper. We
shouldn't need to init the clock/timer/gpio/i2c init twice, so just have it
in SPL.

Prior to this change we set the gd pointer early so that we can store
data in it. This becomes problematic for DM changes as well as being
odd in general. Re-work the code paths so that we don't need to set the
gd pointer so early and instead can rely upon the normal setting of it.
In order to do this we do need to move certain calls from s_init into
spl_board_init(), mainly preloader_console_init and
save_omap_boot_params.
