Trying to boot from an ext4 rootfs fails due to us defaulting to ext3.
While the downstream T20/T30 L4T kernel has issues with ext4 later TK1
L4T should work just fine with it. Hence enable ext4 for sdboot and
usbboot on TK1.

Add SDP (Serial Downloader Protocol) implementation for U-Boot. The
protocol is used in NXP SoCs boot ROM and allows to download program
images. Beside that, it can also be used to read/write registers and
download complete Device Configuration Data (DCD) sets. Currently,
this implementation only supports downloading images and reading
registers.

Implement early TPS6586X PMIC rail configuration setting SM0 being
VDD_CORE_1.2V to 1.2 volts and SM1 being VDD_CPU_1.0V to 1.0 volts.
While those are PMIC power-up defaults the SoC might have been reset
separately with certain rails being left at lower DVFS states which
is e.g. the case upon watchdog reset while otherwise nearly idling.

On popular request enable the display driver on Colibri T30. A few
notes about some things encountered during porting: While analogue VGA
(e.g. via the on-carrier RAMDAC) worked just fine from the beginning
the EDT display flickered like crazy which turned out to be a pin
muxing issue. Unfortunately the PWM pin muxing wasn't any good neither
which made that display stay dark. Enjoy.

On popular request make the display driver from T20 work on T30 as
well. Turned out to be quite straight forward. However a few notes
about some things encountered during porting: Of course the T30 device
tree was completely missing host1x as well as PWM support but it turns
out this can simply be copied from T20. The only trouble compiling the
Tegra video driver for T30 had to do with some hard-coded PWM pin
muxing for T20 which is quite ugly anyway. On T30 this gets handled by
a board specific complete pin muxing table. The older Chromium U-Boot
2011.06 which to my knowledge was the only prior attempt at enabling a
display driver for T30 for whatever reason got some clocking stuff
mixed up. Turns out at least for a single display controller T20 and
T30 can be clocked quite similar. Enjoy.

Synchronize initramfs related configuration options and improve
memory layout. The memory layout with an offset of 16MiB allows
to boot bigger kernels. With AUTO_ZRELADDR, which is pretty much
the standard nowadays, the kernel relacates itself to PC masked
with 0xf8000000 plus a text offset of 0x8000 (hence 0x80008000 for
Vybrid). With a 16MiB offset from the start of memory and a 16MiB
distance to the device-tree, we allow kernel up to ~16MiB.

Add writebcb command which creates a NAND Boot Configuration Block
(BCB) at the beginning of the active flash device. The BCB stores
the information for the SoC internal boot ROM where the application
with a valid IVT header can be found on the NAND device. The first
two argument of the command need an offset of the NAND device where
the primary and secondary application can be found.
Typically, U-Boot is the application which gets loaded by the boot
ROM. Hence, the offset address need to be the address where U-Boot
(u-boot.imx along with a 0x400 long prefix) is stored on the device.
At least one location is mandatory.
Currently only the FCB (Firmware Configuration Block) is written to
the device. The DBBT (Discovered Bad Block Table) is optional and
not created by writebcb currently.

Use two separate partitions for the two firmware instances. Also
resize them to be of the same size which also makes the start of
the UBI partition nicely aligned to 0x400000.
In order to detect the new MTD layout and whether we run a U-Boot
with the new BCB format or not, introduce a variable called
"updlevel" which we can use in update/upgrade scripts.

Limit memory used for relocation of FDT or initrd. This is
required to make sure that relocated artifacts are within lowmem.
If fdt_high or initrd_high are not set, U-Boot automatically
relocates artifacts to the end of memory. But this area won't
be part of lowmem and hence will not be accessible by the kernel
during early boot.
With VM split set to 2G/2G (i.MX default), only the 2GB Apalis
iMX6 is affected by that issue. With VM split set to 3G/1G (ARM
default) also modules with 1GB of memory are affected. With the
latter the amount of lowmem will be 760MiB.
The value must also not exceed available memory! Use a safe value
of 512MiB for Apalis and 256MiB for Colibri.

Specify standard padding for payload to 68KB. This is derived from
the maximum header size plus maximum SPL size. It matches the
already defined offset for SD/eMMC devices (69KB) too. This allows
to use the u-boot-with-spl.imx build target to generate a directly
flashable image which can be flashed using:
dd if=u-boot-with-spl.imx of=/dev/mmcblk0 bs=512 skip=2
While the patch has been created with SD/eMMC in mind, this also
works with other boot media. The board file needs to configure the
media specific (absolute) payload offset accordingly. Especially
the IVT offset is boot media specific and can be retrieved from the
reference manual (Table 8-25. Image Vector Table Offset and Initial
Load Region Size). For NAND boot a define like this should do the
job:
#define CONFIG_SYS_NAND_U_BOOT_OFFS (SPL_PAD_TO + 0x400)

This patch adds board support for the Toradex Apalis TK1 a computer on
module which can be used on different carrier boards.
The module consists of a Tegra TK1 SoC, a PMIC solution, 2 GB of DDR3L
RAM, a bunch of level shifters, an eMMC, a TMP451 temperature sensor
chip, an I210 gigabit Ethernet controller and a SGTL5000 audio codec.
Furthermore, there is a Kinetis MK20DN512 companion micro controller for
analogue, CAN and resistive touch functionality.
For the sake of ease of use we do not distinguish between different
carrier boards for now as the base module features are deemed
sufficient enough for regular booting.
The following functionality is working so far:
- eMMC boot, environment storage and Toradex factory config block
- Gigabit Ethernet
- MMC/SD cards (both MMC1 as well as SD1 slot)
- USB client/host (dual role OTG port as client e.g. for DFU/UMS or host,
other two ports as host)

Commit 35c204d8a9d0 ("nand: reinstate lazy bad block scanning")
introduced lazy BBT scanning. However, some controller do parts
of the initialization (mxs_nand.c) during scan_bbt, hence for
those controllers the BBT must be scanned at initialization time.
In most situation the U-Boot environment gets read first, and
the U-Boot environment code checks for bad blocks first. Checking
for bad blocks will ask for scan_bbt before reading the first page,
hence in most situation the issue does not appear in practice.
However, when there is no environment configured, other code might
access NAND first which does not explicitly checks for bad blocks,
in those cases ECC reads will fail always.
