f0f6724f86 ARM: configs: cm_fx6: improve default environment
Currently, entire script segments have to be changed in the default
environment to change the kernel image location or to append kernel
cmdline parameters. In the later case this has to be changed for
every possible boot device.

Introduce new variables for kernel image locations and boot device
independent kernel parameters to make it easier to change these
settings.

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.

For A53, data coherency is enabled only when the CPUECTLR.SMPEN bit is

If not enabled, the cache is not coherent with other cores and
data corruption could occur.

For A57/A72, SMPEN bit enables the processor to receive instruction
cache and TLB maintenance operations broadcast from other processors
in the cluster. This bit should be set before enabling the caches and
MMU, or performing any cache and TLB maintenance operations.

085e64dd42 test/py: strip VT100 codes from match buffer
Prior to this patch, any VT100 codes emitted by U-Boot are considered part
of a command's output, which often causes tests to fail. For example,
test_env_echo_exists executes printenv, and then considers any text on a
line before an = sign as a valid U-Boot environment variable name. This
includes any VT100 codes emitted. When the test later attempts to use that
variable, the name would be invalid since it includes the VT100 codes.
Solve this by stripping VT100 codes from the match buffer, so they are
never seen by higher level test code.

The codes are still logged unmodified, so that users can expect U-Boot's
exact output without interference. This does clutter the log file a bit.
However, it allows users to see exactly what U-Boot emitted rather than a
modified version, which hopefully is better for debugging. It's also much
simpler to implement, since logging happens as soon as text is received,
and so stripping the VT100 codes from the log would require handling
reception and stripping of partial VT100 codes.

2307ea4053 common: Always include errno.h in common.h
We want people using errnos for errors instead of -1, so make it easy
by always including the definition of all the errnos.

ec5507707a video: tegra: Move to using simple-panel and pwm-backlight
We have standard drivers for panels and backlights which can do most of the
work for us. Move the tegra20 LCD driver over to use those instead of custom
code.

This patch includes device tree changes for the nvidia boards. I have only
been able to test seaboard. If this patch is applied, these boards will
also need to be synced with the kernel, and updated to use display-timings:

   - colibri
   - medcom-wide
   - paz00
   - tec

Sync everything except the display panel, which will come in a future patch.
One USB port is left disabled since we don't want to support it in U-Boot.

862887d883 errno: Allow errno_str() to be used without CONFIG_ERRNO_STR
The pmic framework uses errno_str() and this requires board that use it to
enable CONFIG_ERRNO_STR to avoid a build error. Update the header to provide
a NULL error message when CONFIG_ERRNO_STR is not defined, and fix the build
error.

This will show as "(null)" when U-Boot prints it.
