When moving configs, it is important to know what was defined in the
config header even if it duplicates the configs coming from Kconfig.

This is specifically needed for the case where a config is set to
default 'y' in the Kconfig. This would previously cause the actual value
from the include config to be filtered out, and moveconfig.py would
think that it was 'n'... This means that the value that should be 'y'
is now (in every defconfig) set to 'not set'.

tools/moveconfig.py now defines KCONFIG_IGNORE_DUPLICATES to prevent the
filtering from happening and selecting wrong values for the defconfig.

This will ensure that the order of the defconfig entries will always
match that of the Kconfig files. After one slightly painful (but
still early in the process) pass over all boards, this should keep
the defconfigs clean from here on.

Users must edit the Kconfig first to add the menu entries and then run
moveconfig.py to update the defconfig files and the include configs.

As such, moveconfig.py cannot compare against the '.config' contents.

This tool was originally written for my local use to ease the task
of tons of CONFIG moves, but there have been some requests for
mainlining it.
So, I have tidied up the code with nicer comments, and here it is.

See the comment block of the script for usage.

The first draft was
http://patchwork.ozlabs.org/patch/430422/

Main updates are:
  - Adapted to the single .config configuration
  - Support colored log
  - Support moving multiple options at once
    (and take configs via input file only)
  - Continue even if some boards fail
    (Idea provided by Joe Hershberger)
  - Add more options
  - More comments and code cleanups

The CPU temperature grade from OTP is now used to define the critical
threshold at which point we busyloop until we are below, however this
threshold is still too low.

Instead of 20C below the max CPU temperature, change it to 5C defined now
by TEMPERATURE_HOT_DETLA for clarity. Rename 'passive' to 'critical'
as that better defines our use case here. Additionally change the output
of the busyloop message to show the max CPU temperature as well as current.

Before:
CPU Temperature is 101 C, too hot to boot, waiting...
CPU Temperature is 101 C, too hot to boot, waiting...

After:
CPU Temperature (101C) too close to max (105C) waiting...

Due to licensing issues, the files ps7_init.c/h are not able to be
distributed with U-Boot source code.  Recent Xilinx tools also
provide the GPL variants (ps7_init_gpl.c/h), compatible with U-Boot
license.

Prior to this commit, we had to copy ps7_init files into
board/xilinx/zynq/ before the compile.

To be more user-friendly, let's include ps7_init_gpl.c/h for
Zedboard, MicroZed, ZC702, ZC706.

These init code have been taken from the hwplatform_templates
directory of Xilinx SDK 2014.4.

You can still use customized ps7_init_gpl.c/h by enabling
CONFIG_ZYNQ_CUSTOM_INIT.  The recommended directory for storing them
is now board/xilinx/zynq/custom_hw_platform, but board/xilinx/zynq
is still supported for backward compatibility.  The latter emits
a warning message to prompt users to gradually switch to the new
directory.

and were built as follows:

ZC702: make zynq_zc70x_defconfig && make
ZC706: make zynq_zc70x_defconfig && make DEVICE_TREE=zynq-zc706

This commit introduces separate configuration for them, which makes
the next commit much easier.

Going forward, the recommended build commands are:

ZC702: make zynq_zc702_defconfig && make
ZC706: make zynq_zc706_defconfig && make

Although the old work flow is still supported, CONFIG_TARGET_ZC70X
has been marked as deprecated.  If used, the warning message is

Use in-band bad block table (NAND_BBT_NO_OOB) which allows to
use the full OOB for hardare ECC purposes. Since there is no
ECC correction on the OOB it is also safer to use in-band area
to store the bad block table marker.
Signed-off-by: NStefan Agner <stefan@agner.ch>

Implement read of OOB area only. When using column and sector size
properties, only parts of the page can be read. However, this works
only when hardware ECC is disabled, otherwise the ECC engine would
ruin the data in the buffer. To allow OOB only reads, three points
had to be addressed:
- Set ECC mode per command.
- Handle NAND_CMD_READOOB seperate. Make sure column and sector
  size is correctly set up, while disabling ECC.
- Now, the OOB data end up at the beginning of the buffer. Remove
  the special handling of OOB (spareonly).

Especially bad block scans benefit from this change. On a 512MiB
SLC NAND device, the bad block scan took 1.5s less than before.

Signed-off-by: NStefan Agner <stefan@agner.ch>

To improve performance we remember the current page in the buffer
and avoid reading it twice. This implicit page cache increases
complexity while does not increase performance in real world cases.
This patch removes that feature.
