b7b2067062 colibri_t20: fix reset out pin
Make sure SODIMM pin 87 nRESET_OUT is released properly by explicitly
setting its pin mux function to GMI. This solves some issues with e.g.
USB not being fully operational on carrier boards with USB hubs
connected to reset if U-Boot got loaded via recovery mode aka rcm.

10ef82d398 colibri_t20: disable PMIC sleep mode on low supply voltage
The Colibri T20's PMIC enters a sleep mode on low supply voltage < 3.0V
±2.5% (2.92...3.08V). Rising the main supply voltage again does not
bring it back to regular operation. Not even a full reset does bring
the module back. A full power cycle was required to reboot the system.
A long positive pulse on the PMICs resume pin also reboots the system
but this pin is only accessible as a test point on the module.

This patch configures the PMIC through I2C to not enter this sleep mode
plus force it to normal state upon sleep request exit should this ever
happen.

a5825625e5 apalis/colibri_t20/t30: integrate recovery mode detection
Allow detecting whether or not U-Boot was launched through the
recovery mode of the resp. NVIDIA SoC.

Make use of a board specific arch_misc_init() and enable the same via
CONFIG_ARCH_MISC_INIT configuration option.

237c36379c ARM: tegra: move NVIDIA common files to arch/arm/mach-tegra
All the Tegra boards borrow the files from board/nvidia/common/
directory, i.e., board/nvidia/common/* are not vendor-common files,
but SoC-common files.

Move NVIDIA common files to arch/arm/mach-tegra/ to clean up
Makefiles.

As arch/arm/mach-tegra/board.c already exists, this commit renames
board/nvidia/common/board.c to arch/arm/mach-tegra/board2.c,
expecting they will be consolidated as a second step.

76a30fedd4 ARM: tegra: colibri_t20: fix nand pinmux
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
to avoid clashing settings.

e57c6e5b50 ARM: tegra: rename colibri_t20 board/configuration/device-tree
In accordance with our other modules supported by U-Boot and as agreed
upon for Apalis/Colibri T30 get rid of the carrier board in the board/
configuration/device-tree naming.

While at it also bring the prompt more in line with our other products.
