a1f79c2170 arm: wandboard: move CONFIG_MXC_UART to defconfig
For using a debug UART on the Wandboard CONFIG_MXC_UART=y must be set in
the .config file.

To avoid duplicate definitions move the setting from
include/configs/wandboard.h to configs/wandboard_defconfig.

Document the debug UART settings in the README.

a09fea1d28 env: Finish migration of common ENV options
- In ARMv8 NXP Layerscape platforms we also need to make use of
  CONFIG_SYS_RELOC_GD_ENV_ADDR now, do so.
- On ENV_IS_IN_REMOTE, CONFIG_ENV_OFFSET is never used, drop the define
  to 0.
- Add Kconfig entry for ENV_ADDR.
- Make ENV_ADDR / ENV_OFFSET depend on the env locations that use it.
- Add ENV_xxx_REDUND options that depend on their primary option and
  SYS_REDUNDAND_ENVIRONMENT
- On a number of PowerPC platforms, use SPL_ENV_ADDR not CONFIG_ENV_ADDR
  for the pre-main-U-Boot environment location.
- On ENV_IS_IN_SPI_FLASH, check not for CONFIG_ENV_ADDR being set but
  rather it being non-zero, as it will now be zero by default.
- Rework the env_offset absolute in env/embedded.o to not use
  CONFIG_ENV_OFFSET as it was the only use of ENV_OFFSET within
  ENV_IS_IN_FLASH.
- Migrate all platforms.

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.

066d97c733 wandboard: Add support for the latest revd1 revision
Latest wandboard hardware revision is revd1, which brings the following
new features:

- PFUZE100 PMIC
- AR8035 Ethernet PHY
- Upgrade Wifi/BT chip to BCM4339/BCM43430.

The detection mechanism is to probe the PMIC and when it is
found, then the revision of the board is revd1.

As the detection is done via PMIC, we need to print the board version
at a later stage via CONFIG_DISPLAY_BOARDINFO_LATE and also need
to disable CONFIG_DISPLAY_BOARDINFO, which is done much earlier.

Make the necessary adjustments for the AR8035 PHY to work on revd1.

When running a SPL target, which supports multiple MX6 variants we cannot

such decision is done in build-time currently.

Remove the CONFIG_IPUV3_CLK option and let the IPU clock frequency be

2be296538e Convert CONFIG_ENV_IS_IN_MMC/NAND/UBI and NOWHERE to Kconfig
This converts the following to Kconfig:
   CONFIG_ENV_IS_IN_MMC
   CONFIG_ENV_IS_IN_NAND
   CONFIG_ENV_IS_IN_UBI
   CONFIG_ENV_IS_NOWHERE

In fact this already exists for sunxi as a 'choice' config. However not
all the choices are available in Kconfig yet so we cannot use that. It
would lead to more than one option being set.

In addition, one purpose of this series is to allow the environment to be
stored in more than one place. So the existing choice is converted to a
normal config allowing each option to be set independently.

There are not many opportunities for Kconfig updates to reduce the size of
this patch. This was tested with

   ./tools/moveconfig.py -i CONFIG_ENV_IS_IN_MMC

And then manual updates.  This is because for CHAIN_OF_TRUST boards they
can only have ENV_IS_NOWHERE set, so we enforce that via Kconfig logic
now.

67ff9e11f3 wandboard: move environment partition farther from u-boot.img
Recently I started to notice that u-boot.img built for Wandboard
by some toolchains becomes so large that it basically overlaps with
U-Boot environment area on SD-card.

According to
http://wiki.wandboard.org/index.php/Boot-process#sdcard_boot_data_layout
Wandboard's SD-card layout is as follows:
------------------------------>8---------------------------
Acked-by: Otavio Salvador <otavio@ossystems.com.br>
Acked-by: Fabio Estevam <fabio.estevam@nxp.com>

==========================================================
1. 0x00000000           Reserved For MBR
2. 0x00000200   512     Secondary Image Table (optional)
3. 0x00000400   1024    uBoot Image (Starting From IVT)
4. 0x00060000   393216  start of uboot env (size:8k)
5. 0x00062000           end of uboot env
6. 0x00100000   1048576 Linux kernel start
7. 0x0076AC00   7777280 start of partition 1
------------------------------>8---------------------------

So for U-Boot we have 383kB (392192 bytes).

But in up to date U-Boot for Wandboard we build separately
 a) SPL
 b) u-boot.img

which gives us a bit more detailed SD-card layout:
------------------------------>8---------------------------
==========================================================
1. 0x00000000           Reserved For MBR
2. 0x00000200   512     Secondary Image Table (optional)
3. 0x00000400   1024    SPL
4. 0x00011400   70656   u-boot.img
5. 0x00060000   393216  start of uboot env (size:8k)
6. 0x00062000           end of uboot env
...
------------------------------>8---------------------------

>From that layout we may calculate amount of space reserved for
u-boot.img. It's just 315kb (322560 bytes).

Now if I build U-Boot with Sourcery CodeBench ARM 2014.05 produced
u-boot.img is already more than we expected
(323840 bytes instead of "< 322560"):
------------------------------>8---------------------------
ls -la u-boot.img
-rw-rw-r-- 1 user user 323840 Jul  5 07:38 u-boot.img
------------------------------>8---------------------------

Funny enough if I rebuild U-Boot with ARM toolchain available in
my Fedora 23 distro u-boot.img becomes a little bit smaller:
------------------------------>8---------------------------
ls -la u-boot.img
-rw-rw-r-- 1 user user 322216 Jul  5 07:39 u-boot.img
------------------------------>8---------------------------

What's worse this problem might not affect people most of the time
because what happens people would just copy u-boot.img on SD-card and
live in happiness with it... well until somebody attempts to save
environment in U-Boot with "saveenv" command which will simply
overwrite the very end of u-boot.img.
That will lead to unusable SD-card until user dd u-boot.img on
SD-card again.

I may foresee this issue in the future to become more visible once we
add more features in U-Boot for Wandboard or just existing code base
becomes bulkier and people will consistently get larger u-boot.img
files produced.

IMHO there's an obvious solution for all that - just move U-Boot's env
to the very end of the gap between U-Boot and the first real partition
on the SD-card. This patch will follow
8fb9eea565 ("mx6sabre_common: Fix U-Boot corruption after 'saveenv'").
So env is still not in the very end of the gap (obviously 256kb is way
too much for U-Boot's env) but at least we have now the same
partitioning for i.MX6 boards.
