This adds support for Colibri iMX7 Dual 1GB modules which come
with on-board eMMC storage (whereas the other Colibri iMX7
modules use raw NAND). A subselection (variant) for the
Colibri iMX7 target is used to maximize sharing.

The ISO partition support is mainly useful for CD drives which
are not really common in embedded space and in general anymore.
Removing ISO partition support saves 1.5kB and gets rid of the
somewhat confusing message when no partition table is present:
** First descriptor is NOT a primary desc on 0:1 **

Allow optionally bringing up the Apalis type specific 4 lane PCIe port
as well as the PCIe switch as found on the Apalis Evaluation board. In
order to avoid violating the PCIe reset timing do this by overriding the
tegra_pcie_board_port_reset() function. Note however that both the
Apalis type specific 4 lane PCIe port as well as the regular Apalis PCIe
port are also left disabled in the device tree by default.

Introduce a weak tegra_pcie_board_port_reset() function by default
calling the existing tegra_pcie_port_reset() function. Additionally add
a tegra_pcie_port_index_of_port() function to retrieve the specific PCIe
port index if required. This allows overriding the PCIe port reset
functionality from board specific code as e.g. required for Apalis T30
and Apalis TK1.

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

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.

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.
