The imx53 SOC features 128kB of internal SRAM which is commonly used in
early stages of barebox to store the stack. Avoid magic numbers while
addressing this RAM.

All i.MX images are nowadays built with the imx-image tool, so we do not
need the header files and Kconfig options anymore. Remove them.

This file originates in Linux. Linux has it under include/linux/
directory since commit dccd2304cc90.
Let's move it to the same place as well in barebox.
This commit was generated by the following commands:
find -name '*.[chS]' | xargs sed -i -e 's:<sizes.h>:<linux/sizes.h>:'
git mv include/sizes.h include/linux/

This is similar to what we do on imx6 and makes sure we
apply the errata workarounds early.

For i.MX devicetree boards the console= parameter is automatically
generated and can be dropped from the env files. If a file becomes
empty then, remove it.

The i.MX barebox update handlers take an optional dcd table as argument.
This can be used to add the correct dcd data to the image before flashing
it.
This mechanism is quite complicated and largely unused, so remove it. With
this it is only possible to flash the exact image passed to barebox_update,
which is what is mostly done anyway.

Mostly to make it clear that boarddata needs to be
something we can dereference.
As this is a pretty invasive change, use the opportunity
to make the signature 64bit safe.

With multiboard support the compiletime generated BOARDINFO string
gets more and more meaningless. This removes it from Kconfig and
replaces it with a variable that can be set at boardlevel.
Also many boards have a standard setting for the hostname in the
environment. This patch also moves the standard to C code by calling
barebox_set_hostname().

clock_notifier_call_chain() can't be called before init time. Protecting
it with IS_ENABLED(__PBL__) is not enough. This patch splits out a new
imx53_init_lowlevel_early which can be called before init time and does
not have the call to clock_notifier_call_chain() in it.

This patch seperates the imx independent from the arch independent code. The
following functions and enums are renamed:
- imx_bootsource() -> bootsource_get()
- imx_set_bootsource() -> bootsource_set()
- enum imx_bootsource -> enum bootsource

Having the board config file in /env/init has the problem that
the settings in /env/config are overwritten in the init sequence.
This moves the config-board files to /env/ and sources them explicitly
from /env/bin/init before sourcing /env/config

(i.MX21, i.MX6) use hardcoded base addresses.

This patch fixes a linker error when PBL_IMAGE=n and DO_LOW_LEVEL_INIT=n.
In this configuration the symbol reset() was present multiple times,
and prevented the barebox image to be linked.

This patch remove a superfluous DCD command in TX53-xx30 flash header.
The entry DCD_WR_CMD(0x21c) just duplicates the contents of the last
imx_flash_header_v2 struct member dcd.
Removal of this DCD entry is needed to make the TX53 board boot again
from NAND.

We support two different board revisions, both of which only differ
in the dcd table, so we can support both in a single binary with the
cost of storing both dcd tables in the binary.

The idea of having /env/init/* scripts was to make the configuration
more flexible and customizable for boards. It turned out though that
people (including myself) do not find the place where they should
change these settings.
So this patch brings back /env/config for defenv-2. The individual
env/init/* scripts are removed and their content is added to
/env/init/config-board. This makes the values from /env/init/config-board
the board specific defaults which can be overwritten in /env/config.
