In the beginning, we did SPL -> TPL -> U-Boot, but after clarification
of the real ordering swapped SPL and TPL.
It seems some renames were forgotten and may confuse future readers, so
also swap these to reflect the actual ordering.

There was still a static ram value set in the rk3188-board from the
time where we didn't have actual sdram init code.
Now the sdram init leaves the ram information in SYS_REG2 and we can
decode it similarly to the rk3288.
Right now we have two duplicates of that code, which is still ok and
doesn't really count as common code yet, but if we get a third copy
at some point from a newer soc, we should think about moving that to
a more general position.

The config options for pinctrl on the RK3188, RK3288, RK3328 and
RK3399 previously showed up in menuconfig with the generic string
descriptor "Rockchip pin control driver" requiring one to look through
the help/full description to identify which chip each menu entry was
for.
This change renames each option with the chip-name in the description
string to make it easy to identify the configuration options in
menuconfig.

To simplify the creation of AArch64 SPL images for the RK3399, we
use the ENABLE_ARM_SOC_BOOT0_HOOK option and prepend 4 bytes of
padding at the start of the text section. This makes it easy for
mkimage to rewrite this word with the 'RK33' boot magic.
This change brings logic to calculate the header size and allocate
the header back in sync. For the RK3399 we now limit the header to
before the payload (i.e. the 'header0' and the padding up to the
actual image) and overwrite the first word (inserted by the
boot0-hook for this purpose) with the 'RK33' magic in-place.

The SPL binary needs to be prefixed with the boot magic ('RK33' for
the RK3399) on the Rockchip platform and starts execution of the
instruction word following immediately after this boot magic.
This poses a challenge for AArch64 (ARMv8) binaries, as the .text
section would need to start on the odd address, violating natural
alignment (and potentially triggering a fault for any code that
tries to access 64bit values embedded in the .text section).
A quick and easy fix is to have the .text section include the 'RK33'
magic and pad it with a boot0 hook to insert 4 bytes of padding at the
start of the section (with the intention of having mkimage overwrite
this padding with the appropriate boot magic). This avoids having to
modify the linker scripts or more complex logic in mkimage.

The RK3399 boot code (running as AArch64) poses a bit of a challenge
for SPL image generation:
* The BootROM will start execution right after the 4-byte header (at
the odd instruction word loaded into SRAM at 0xff8c2004, with the
'RK33' boot magic residing at 0xff8c2000).
* The default padding (during ELF generation) for AArch64 is 0x0,
which is an illegal instruction and the .text section needs to be
naturally aligned (someone might locate a 64bit constant relative
to the section start and unaligned loads trigger a fault for all
privileged modes of an ARMv8)... so we can't simply define the
CONFIG_SPL_TEXT_BASE option to the odd address (0xff8c2004).
* Finally, we don't want to change the values used for padding of
the SPL .text section for all ARMv8 targets to the instruction
word encoding 'nop', as this would affect all padding in this
section and might hide errors that would otherwise quickly trigger
an illegal insn exception.
To deal with this situation, we modify the rkimage generation to
- understand the fact that the RK3399 needs to pad the header to an
8 byte boundary using an AArch64 'nop'
- the necessary logic to adjust the header_size (which controls the
location where the payload is copied into the image) and to insert
this padding (AArch64 insn words are always little-endian) into
the image following the 4-byte header magic.

The RC4 encoding works on full blocks, but the calculation of the
starting offset and size are needlessly complicated by using a
reference value known to be offset into a block by the size of the
header and then correcting for the (hard-coded) size of the header
(i.e. 4 bytes).
We change this over to use the RK_SPL_HDR_START directly (which is
known to be on a block boundary).

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)

bit 1: Core 1 (slave)
* Now there's no need to select "manual" mode of core start
