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.
Fixes: 90df2a955e3c ("defaultenv: Convert init script to C")

Allow specifying cdev's filetype explicitly to support the cases where
the type of a cdev is known apriori, yet cannot be determined by
reading the cdev's content.

So far we only refreshed the unused firmware when it differs from the
used one, but we also have to refresh it when the pages need a cleanup
(-EUCLEAN returned).

The caller of read_firmware() expects a positive return value when a
firmware is readable but needs a cleanup, so return 1 instead of
-EUCLEAN. Without this a firmware will never be refreshed.

read_firmware_all() prints some info messages at the end. There's
one case where we bail out early and no messages are printed. This
is confusing, drop the return and always print messages.

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.

It's hard to get more complicated things right in hush. This commit
converts the /env/bin/init script to C code. With this we get a better
error handling and better control what is being done.
If /env/bin/init exists in the environment then it is still executed
instead of the corresponding C code.

When global.autoboot_abort_key is set to ctrl-c then the user is
expected to press ctrl-c to get to the prompt. The user might press
ctrl-c before the init script runs the "timeout" command. In this
case the init script is aborted at arbitrary places which leads to
inconsistent results depending on the place it is aborted.
This patch introduces the global.console.ctrlc_allowed variable.
When this variable is set to false ctrl-c is ignored entirely.
The variable is set to false by default and changed to true in
the init script.

It's easy to get stuck in an infinite loop in the hush shell:
while true; do sleep 1; done
The 'sleep' command will check for ctrl-c with the ctrlc() function. This
will abort the sleep command. Hush then checks for ctrl-c again in the
loop. The ctrl-c in the buffer has already been eaten by the sleep
command, so the loop will continue.
With this patch we remember the presence of a ctrl-c character in a
variable instead of checking for a new character each time. The
variable must be resetted explicitly by calling ctrlc_handled() which
will be called by the shell in the outer loop.
