Being global variable with 0 value it falls into .bss area which we may
only use after relocation to RAM. And right afetr relocation we zero
.bss - effectively cleaing register address set for early console.
Now with pre-set value "regs" variable is no longer in .bss and this way
safely survives relocation.

Pingroup ATC seems to come out of reset with config set to NAND, so we
need to explicitly configure some other function to this group in order

Even the 8-bit case needs KBCB configured, as pin D7 is located in this
pingroup.
Please note that pingroup ATC seems to come out of reset with its
config set to NAND so one needs to explicitly configure some other
function to this group in order to avoid clashing settings which is
outside the scope of this patch.

A while ago I got Russell to change the machine type of our Colibri T20
from COLIBRI_TEGRA2 to COLIBRI_T20 which at least in parts is also
reflected in his machine registry:
http://www.arm.linux.org.uk/developer/machines/list.php?id=3323
For us it is really very beneficial to actually still be able to boot
downstream L4T kernel with its working hardware accelerated
graphics/multimedia stack albeit it being proprietary/closed-source.

Testing showed, that commands like STATUS made the buffer dirty
when executed with NFC_SECSZ set to the page size. It looks
like the controller transfers bogus data when this register
is configured. When setting it to 0, the buffer does not get
altered while the status command still seems to work flawless.

The driver tries to re-use the page buffer by storing the page
number of the current page in the buffer. The page is only read
if the requested page number is not currently in the buffer. When
a block is erased, the page number is marked as invalid if the
erased page equals the one currently in the cache. However, since
a erase block consists of multiple pages, also other page numbers
could be affected.
The commands to reproduce this issue (on a written page):
> nand dump 0x800
> nand erase 0x0 0x20000
> nand dump 0x800
The second nand dump command returns the data from the buffer,
while in fact the page is erased (0xff).
Avoid the hassle to calculate whether the page is affected or not,
but set the page buffer unconditionally to invalid instead.

This command is only enabled by one board, complicates the NAND code,
and doesn't appear to have been functioning properly for several
years. If there are no bad blocks in the NAND region being written
nand_write_skip_bad() will take the shortcut of calling nand_write()
which bypasses the special yaffs handling. This causes invalid YAFFS
data to be written. See
http://lists.denx.de/pipermail/u-boot/2011-September/102830.html for
an example and a potential workaround.
U-Boot still retains the ability to mount and access YAFFS partitions
via CONFIG_YAFFS2.

Previously NAND writes were only verified when CONFIG_MTD_NAND_VERIFY_WRITE
was defined. On boards without this define writes could fail silently.
Boards with CONFIG_MTD_NAND_VERIFY_WRITE could prematurely report
failures which ECC could correct.
Add a verification step after all "nand write[.x]" commands to ensure the
writes were successful. The verification uses ECC for for "normal"
writes, but does not for raw and yaffs writes. Some test cases which
inject fake bad bits on a 2K page flash are below.
Test cases with CONFIG_MTD_NAND_VERIFY_WRITE defined:
Example of an ECC write which previously failed when
CONFIG_MTD_NAND_VERIFY_WRITE was defined, but now succeeds because ECC
is used during verification:
nand erase 0 0x10000
dhcp /somefile
mw.b 0x10000 0xff 0x2000
mw.b 0x10020 0xfe 1
nand write.raw 0x10000 0x800 1
mw.b 0x1000020 0x01 1
nand write 0x1000000 0x800 0x1800
Test cases without CONFIG_MTD_NAND_VERIFY_WRITE defined:
Example of an ECC write which previously silently failed:
nand erase 0 0x10000
dhcp /somefile
mw.b 0x10000 0xff 0x2000
mw.b 0x10020 0x00 1
nand write.raw 0x10000 0x800 1
mw.b 0x1000020 0xff 1
nand write 0x1000000 0x800 0x1800
Example of a raw write which previously failed silently due to stuck
data bit, but now errors out:
nand erase 0 0x10000
dhcp /somefile
mw.b 0x10000 0xff 0x2000

with WCR_WDW set, the watchdog won't trigger if we bootet linux and idle
around while the watchdog is not triggered. It seems the timer makes
progress very slowly if at all. I managed to remain 20minutes alive
while the timeout was set to 60secs. It reboots within 60secs if I start
a busyloop in userland (something like "while (1) { }").
While I don't see a reason why the WDT should not be running while the
CPU is in idle, I'm dropping this bit.

Before add CONFIG_SYS_MALLOC_F and CONFIG_SYS_MALLOC_F_LEN,
uboot will complains "CPU: Temperature: Can't find sensor device".
This is because DM and DM_THERMAL are enabled, but SYS_MALLOC_F
is not configured.
After applying this patch, uboot can correctly detect the temperature.

Add basic SECO MX6Q/uQ7 board support (Ethernet, UART, SD are supported).
It also adds a Kconfig skeleton to later add more SECO board (supporting
SoC and board variants).

IMX_CONFIG is currently passed via the SYS_EXTRA_OPTIONS which is marked
as deprecated.
Add a new Kconfig file under arch/arm/imx-common and define the
IMX_CONFIG Kconfig in there.
Each board is supposed to provide a default value pointing to the
appropriate imximage.cfg file.

Freescale boards are currently all defined in arch/arm/Kconfig, which
makes them hard to detect.
Moreover the MX6 SoC variant (Q, D, DL, S, SL) selection is currently
done via the SYS_EXTRA_OPTIONS option which marked as deprecated.
Move to a more standard way to select sub-architecture and board by
creating a Kconfig under arch/arm/cpu/armv7/mx6 and a new ARCH_MX6
option.
Existing MX6 board definitions should be moved in this new Kconfig in
choice menu, and new boards should be directly declared in this menu.
