b75d8dc564 treewide: convert bd_t to struct bd_info by coccinelle
The Linux coding style guide (Documentation/process/coding-style.rst)
clearly says:

  It's a **mistake** to use typedef for structures and pointers.

Besides, using typedef for structures is annoying when you try to make
headers self-contained.

Let's say you have the following function declaration in a header:

  void foo(bd_t *bd);

This is not self-contained since bd_t is not defined.

To tell the compiler what 'bd_t' is, you need to include <asm/u-boot.h>

  #include <asm/u-boot.h>
  void foo(bd_t *bd);

Then, the include direcective pulls in more bloat needlessly.

If you use 'struct bd_info' instead, it is enough to put a forward
declaration as follows:

  struct bd_info;
  void foo(struct bd_info *bd);

Right, typedef'ing bd_t is a mistake.

I used coccinelle to generate this commit.

The semantic patch that makes this change is as follows:

  <smpl>
  @@
  typedef bd_t;
  @@
  -bd_t
  +struct bd_info
  </smpl>

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

fb53e7eb60 ARM: hisilicon: hikey: Fix eMMC with latest ATF & U-Boot
ATF can leave the MMC IP in a state where U-Boot mmc driver
can't enumerate the eMMC.

This patch provides a mmc0_reset_clk() function like we
already so do sd card controller which resets the IP
when entering U-Boot.

With this patch applied eMMC partitions are successfully
enumerated again.

=> mmc dev 0
switch to partitions #0, OK
mmc0(part 0) is current device
=> mmc part

find . -name .git -prune -o ! -path ./scripts/config_whitelist.txt \
-type f -print | xargs sed -i -e 's/CONFIG_DWMMC/CONFIG_MMC_DW/g'

[2] create the entry for MMC_DW in drivers/mmc/Kconfig
    (the prompt and help were copied from Linux)

[3] run "tools/moveconfig.py -y MMC_DW"

[4] add "depends on MMC_DW" to the MMC_DW_ROCKCHIP entry

305b90919e ARM: hisilicon: hikey: Align memory node with upstream kernel
The memory node gets automatically generated by U-Boot
in arch_fixup_fdt(), before passing control to the kernel
using U-Boots representation of the dram banks.

However the upstream kernel uses the memory node to carve-out
regions of RAM for various purposes. To make this work without
changing arch_fixup_fdt() which will effect many platforms
we replicate the upstream memory node layout using the dram
banks.

as more DT lands in the upstream kernel the aim is

9c71bcdc81 ARM: hikey: hi6220: Migrate over to DM_SERIAL and use UART3 by default.
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.

17024e772e ARM: hikey: Remove resetting gd->flags in board_init()
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
causing a synchronus abort.

11ac236320 ARM64: hikey: hi6220: Add u-boot support for the 96boards CE HiKey board.
HiKey is the first 96boards consumer edition compliant board. It features a hi6220
SoC which has eight ARM A53 cpu's.

This initial port adds support for: -
1) Serial
2) eMMC / SD card
3) USB
4) GPIO

It has been tested with Arm Trusted Firmware running u-boot as the BL33 executable.

Notes:

eMMC has been tested with basic reading of eMMC partition into DDR. I have not
tested writing / erasing. Due to lack of clock control it won't be
running in the most performant high speed mode.

SD card slot has been tested for reading and booting kernels into DDR.
It is also currently configured to save the u-boot environment to the
SD card.

USB has been tested with ASIX networking adapter to tftpboot kernels
into DDR. On v2015.07-rc2 dhcp now works, and also USB mass storage
are correctly enumerated.

GPIO has been tested using gpio toggle GPIO4_1-3 to flash the LEDs.
