This patch follows up on a discussion of ways to improve support
for the sunxi FEL ("USB boot") mechanism, especially with regard
to boot scripts, see:
https://groups.google.com/d/msg/linux-sunxi/wBEGUoLNRro/rHGq6nSYCQAJ
The idea is to convert the (currently unused) "pad" bytes in the
SPL header into an area where data can be passed to U-Boot. To
do this safely, we have to make sure that we're actually using
our "sunxi" flavor of the SPL, and not the Allwinner boot0.
The modified mksunxiboot introduces a special signature to the
SPL header in place of the "pub_head_size" field. This can be
used to reliably distinguish between compatible versions of sunxi
SPL and anything else (older variants or Allwinner's boot0).

The sunxi platform currently doesn't seem to make any use of the
asm/arch-sunxi/spl.h file. This patch moves some declarations from
tools/mksunxiboot.c into it.
This enables us to reuse those definitions when extending the
sunxi board code (boards/sunxi/boards.c).

For the upcoming nand support we need a bigger heap, esp. ubi[fs] uses
quite a bit of memory, increase the heap size to 64 MB.
Our video code returns unused reserved framebuffer memory to the kernel
before booting it. Drop the #ifdef-ery and simply always reserve 16 MB.

We only prefix the board defconfig name with the SoC if the SoC is part
of the official board-name, such as with Olimex OLinuxIno boards, for the
Wobo i5 this is not the case so remove the A10s prefix from the defconfig
filename.
Also fix the double listing of A10s-OLinuXino-M_defconfig in MAINTAINERS

The commit: d9dbb97be0
"mmc: dw_mmc: Zap endless timeout" removed endless loop waiting for end
of dw mmc transfer.
For some workloads - dfu test @ Odroid XU3 (sending 8MiB file) -
and SD cards (e.g. MicroSD Kingston 4GiB, Adata 4GiB)
the default timeout is to short.
The new value - 4 minutes (240 seconds) - is the same as the one used in
Linux kernel driver. Such fix should be good enough until we come up
with better fix for this issue.

As 'time(0) | getpid()' will have a lot of duplicated value. It is not a
expected behavior. We expect different value for the seed when when run
it in many times.
So this patch will left shift the getpid() and add to time(0). That
avoid duplicated value.
Test command is like:
% RUN=0; while [ $RUN -lt 10000 ]; do
tools/gen_eth_addr; RUN=$(($RUN+1)); done | sort | uniq | wc -l

Use DM for the pl01x serial driver on hikey. Also allow UART0 or
UART3 to be chosen via Kconfig.
By default we now output to UART3 as the latest version of ATF outputs
to this UART. Also UART3 comes out on the LS connector, as opposed to
UART0 which goes to a unpopulated header.
As part of this change we also enable CONFIG_BOARD_EARLY_INIT_F and
call the pinmux configuration code for the UART. Before we were
relying on ATF having already configured the pin configuration.
NB: Upstream Linux kernel doesn't yet support UART3, so serial console
will still be output on UART0 when booting a upstream kernel.

This causes exceptions and other strange behaviour
when enabling CONFIG_SYS_MALLOC_F_LEN which is required to
migrate the serial driver over to DM_SERIAL.
As GD_FLG_FULL_MALLOC_INIT flag gets reset, after relocation
we don't end up using the full malloc which ultimately ends up

When AM437x EVM is connected to Gigabit switch, it takes
more time to finish auto-negotiation than on a 10/100 switch.
The default 4 second limit times-out more often than not. This is

Before this commit, the Kconfig menu in mach-uniphier only allowed us
to choose one SoC to be compiled. Each SoC has its own defconfig file
for the build-test coverage. Consequently, some defconfig files are
duplicated with only the difference in CONFIG_DEFAULT_DEVICE_TREE and
CONFIG_{SOC_NAME}=y.
Now, most of board-specific parameters have been moved to device trees,
so it makes sense to include init code of multiple SoCs into a single
image as long as the SoCs have similar architecture. In fact, some
SoCs of UniPhier family are very similar:
- PH1-LD4 and PH1-sLD8
- PH1-LD6b and ProXstream2 (will be added in the upcoming commit)
This commit will be helpful to merge some defconfig files for better
maintainability.

Currently, console=ttyS0 is hard-coded in CONFIG_EXTRA_ENV_SETTINGS
and it replaces the bootargs in the chosen node of the device tree
passed to the kernel. This is not preferable because I am going to
add some boards whose console is not ttyS0.
Drop bootargs settings from U-Boot's environment and use the one in
device tree by default.

Currently, IECTRL is enabled after pin-mux settings for the low-level
debugging for PH1-LD4 and PH1-sLD8. While IECTRL is disabled, input
signals are pulled-down, i.e. glitch signal (Low to High transition)
problem occurs if pin-mux is set up first. As a result, one invalid
character is input to the UART block and the auto-boot counting is
terminated immediately.
The correct initialization procedure is:
[1] Enable IECTRL (if IECTRL exists for the pins)
[2] Set up pin-muxing
[3] Deassert the reset of the hardware block
Currently, the low-level debugging is working for PH1-sLD3 and
PH1-Pro4, but just in case, follow the sequence for all the SoCs.

0x00000000 - 0x0fffffff
0x40000000 - 0x4fffffff
are both mapped to the external bus (also called system bus),
so either was OK.
In the newest two SoCs, the former (0x00000000 - 0x0fffffff) is

Going forward, use the latter for the external bus.
