We have one other DT-enabled SAMA5D3 board already:
microchip-ksz8477-evb, which is basically a sama5d3 xplained in
different form factor and with a switch. Mimic what we do there to get
rid of the sama5d3 board code.
Unlike the microchip-ksz9477-evb, the barebox support for this board
includes NAND, which is not yet up to date with respect to DT:
- SMC for NAND configuration has no DT driver. Instead the board
driver create this device
- We don't support the newer NAND DT bindings (EBI). The device trees
fix this up, so barebox sees the old bindings with the upstream
partition layout. In future, this could be fixed.

This updates the barebox NAND layer and parts of the mtd layer to
Linux-5.9.
This patch is huge, but the barebox NAND layer is so far away from the
Linux NAND layer that a step by step update would have taken ages.
Unlike Linux barebox has functions to mark a block as good. This feature
has been preserved. Also barebox used to make NAND write support
optional, this feature is lost during the update for the sake of better
compatibility to the Linux NAND layer.
This patch has been tested:
- GPMI aka nand_mxs on i.MX6
- nand_imx on i.MX25
- nand_omap_gpmc on AM335x
- atmel_nand on Atmel sama5d3
- nand_denali on SoCFPGA
Currently untested:
- nand_orion
- nand_mrvl_nfc
- nand_s3c24xx
The nand_denali driver is tested with the update of that driver to
Linux-5.9 following in the next patch.
I could only test the drivers with the NAND chips found on my boards, so
there's still enough room for regressions, especially given that the
NAND drivers themselves are mostly not updated. With the NAND layer
being up-to-date with Linux it should hopefully be easy to update
drivers to their Linux counterpart as well if necessary.

Instead of adding missing definitions to the existing at91sam9_ddrsdr.h
and adapting the incoming DDRAM initialization code from at91bootstrap,
just replace the lightly used existing header with:
https://github.com/linux4sam/at91bootstrap/blob/v3.8.12/include/arch/at91_ddrsdrc.h
For easier comprehension, the replacement is done in three steps:
This last step copies the memory size querying functions from at91sam9_ddrsdr.h
to at91_ddrsdrc.h, then deletes it and fixes all references.

This adapts all files that were identifed by licensecheck
(https://salsa.debian.org/build-common-team/licensecheck.git) as
licensed under the GPL.
The advantage is that these specifiers are machine-parseable which helps
license conformance, e.g. for packaging barebox in Debian.
While touching these files also do some minor comment reformatting to
get some uniform layout.

Most callers of arm_setup_stack substract a fixed offset of 8, 12 or 16
bytes from the stack top. This is unnecessary as on ARM we have a stack
that decrements before storing values. Substracting this offset probably
goes back to the U-Boot version we forked from. Stop this now.

at91sama5_get_ddram_size() is despite the name specific to the
sama5d3 which it was added alongside of. sama5d4 board code continues
to use it, but accessing SAMA5D3_BASE_MPDDRC (0xffffea00) on
a sama5d4 should result in a Data Abort (Datasheet Figure 5-1)..
Fix this by giving at91sama5_get_ddram_size the mpddrc base
address as argument and migrate users to use one of two helpers
that specify the base address.

[afa: Sam didn't test this exact change, but tested the use
of the critical part: accessing a different register]

barebox_arm_reset_vector() is a global function but we never provided a
prototype anywhere. The prototypes differ for the different boards, so
to provide a common prototype we must harmonize them.
void barebox_arm_reset_vector(uint32_t r0, uint32_t r1, uint32_t r2)
Should be suitable for all boards.

Remove at91_sys_read() and at91_sys_write() since these are no longer
used. This makes mach/io.h empty so remove that aswell.

Currently it's hardcoded for each board which defaultenv version is
used. This is unfortunate since some people like the other defaultenv
version better and may want to select it.
This patch removes the board specific environment path
CONFIG_DEFAULT_ENVIRONMENT_PATH and instead adds it via:
if (IS_ENABLED(CONFIG_DEFAULT_ENVIRONMENT_GENERIC))
defaultenv_append_directory(defaultenv_<board>);
This way we can make sure that the defaultenv-1 board specific bits are
only compiled in when defaultenv-1 is actually in use.
The next step is to make the defaultenv version selection a user visible
choice.

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.
