Both STM32MP BootROM and TF-A first stage expect subsequent bootloader
stages to feature a specific 256-byte long STM32 file header.
Add detection of the header to file_detect_type().
While there's only one version of the header so far, identify the new
header as v1 anyway, so new versions can be unambiguously added.

The imx-bbu-nand-fcb update handler code calls into the NAND driver
to get the ecc strength and bad block marker position. Change the
API so that only a single function is necessary and not three functions.
Also in future the ecc strength will be configurable via device tree.
This means static parameters like page size / oob size are no longer
enough to calculate the ecc strength and so we store a pointer to our
mtd_info struct in a static global variable.

Several tests in ubiformat test for a positive error code where a
negative error code is returned from the called functions. This
is because the original code used tested against errno which is a
positive value.
One place still tests against errno, but the test should be against
the return value from the last function call. Fix that aswell.

This is a barebox adoption of mtd-utils commit
d9cbf6a ("ubiformat: handle write errors correctly"):
| ubiformat: handle write errors correctly
|
| This issue was reported and analyzed by
| Anton Olofsson <anol.martinsson@gmail.com>:
|
| when ubiformat encounters a write error while flashing the UBI image (which may
| come from a file of from stdout), it correctly marks the faulty eraseblock as
| bad and skips it. However, it also incorrectly drops the data buffer which was
| supposed to be written, and reads next block of data.
|
| This patch fixes this issue - in case of a write error, we preserve the current
| data and write it to the next eraseblock, instead of dropping it.

Both the Kernel and mtd-utils have peb torture functions and both
do not mark the block as bad automatically. Instead, the caller
must mark the block as bad when -EIO is returned from the torture
function. Do the same in barebox. This is necessary as the UBI code
otherwise may mark a block as bad twice: Once indirectly in
mtd_peb_torture() and then directly afterwards.

The UBI ec_hdr has an image_seq field. During attaching UBI expects
that its value is the same for all eraseblocks. The value should be
changed with every ubiformat and is used to detect half written images.
In barebox we use a pseudo random number generated with rand() for this
value. The ubiformat command calls srand(get_time_ns()) to initialize
the pseudo random numbber generator. This is done in the option parser,
so when ubiformat() is called directly (from fastboot for example) the
pseudo random number generator is not initialized and we get the same
values after every barebox restart.
This patch moves the pseudo random number generator initialization
to the place where the numbers are generated. Also use random32()
rather than rand() to generate 32bit values rather than 15bit values
(0 - RAND_MAX).

With this pstore only captures barebox log messages printed with pr_*
and dev_*, but no longer anything printed with printf and friends.
When capturing the barebox output with pstore only the log messages are
of interest, but not the ones printed with printf and certainly not
the things typed interactively on the command line. These are logged
currently because we register pstore as a barebox console. Instead, hook
into pr_puts which only outputs the barebox log messages.

The autoboot countdown is part of the init function. This patch factors

they have its own idea how to interrupt the autoboot process.

Commit 90df2a955e3c ("defaultenv: Convert init script to C")
unintentionally changed the way the legacy "/env/bin/init" script is
run, so that it runs in a sub-shell context, effectively changing
`run_command("source /env/bin/init");` to
`run_command("/env/bin/init");`. Therefore, any changes to shell
environment variables made by the script are undone when the script
exits. This patch reverts back to the old behavior.

This is in line with other platforms such as i.MX, which allow
specifying a debug port. As we can't use port indices because
the UARTs aren't mapped consecutively, allow specifying a hex
base at configuration time.
A side effect of this patch is that sama5d4's HAVE_AT91_DBGU2
is now honored as well. Previously anything besides DBGU0
defaulted to DBGU1.

This adds initial support for OP-TEE, see https://www.op-tee.org/
barebox starts in secure mode as usual. When booting a kernel
the bootm code also loads the optee_os binary. Instead of jumping
into the kernel barebox jumps into the optee_os binary and puts
the kernel execution address into the lr register. OP-TEE then
jumps into the kernel in nonsecure mode.
The optee_os binary is passed with the -t option to bootm or
with global.bootm.tee.
Optionally OP-TEE can be compiled into barebox using the builtin firmware
feature. Enable the Kconfig option and place or link your tee binary as
optee.bin into the firmware directory.
The amount of SDRAM which is kept free for OP-TEE is configurable.
This patch was tested on a i.MX6 Nitrogen6x board.

Code implementing .receive_buf() callback can potentially call
serdev_device_write(), which will call serdev_device_poller(). We need
to make sure that such a call is a no-op in order to prevent
corrupting shared data buffer as well as breaking .receive_buf
callback that most likely does not expect that to happen.
