It is working in a way that only minimal timeout is setup to reach
expiration just right after it is setup.
Please make sure that PMUFW is compiled with ENABLE_EM flag.

On U-Boot prompt you can test it like:
ZynqMP> wdt dev watchdog@fd4d0000
ZynqMP> wdt list
watchdog@fd4d0000 (cdns_wdt)
ZynqMP> wdt dev
dev: watchdog@fd4d0000
ZynqMP> wdt expire
(And reset should happen here)

This adds serial parameters that include stop bit mode, parity mode,
and character length. Mark parity and space parity modes are not
supported.

At the moment, the only path to call setconfig directly is DM testing,
however, this affects the size of SPL for DM testing, so it doesn't
apply to SPL.

Both of these drivers are implemented with and without DM that's why more
symbols should be handled.
The most problematic one is enabling DEBUG_UART_PL011 based on
PL01X_SERIAL(DM based) because debug console has type selection based on
it.
	enum pl01x_type type = CONFIG_IS_ENABLED(DEBUG_UART_PL011) ?
				TYPE_PL011 : TYPE_PL010;

Without it pl01x_generic_setbrg() is configuring different registers.

It is not recommended to have aliases for gpio. In past it was used in
Linux for assigning numbers via sysfs which is deprecated and libgpiod
should be used instead.
In U-Boot this number is used for seq number but gpio offset are not
counted from this number. That's why having these aliases only for seq
number is not needed. As is done in Linux it is the best to use full gpio
name instead of sequence number which depends on sequence in binding.

The first change is to trying to find out TF-A load address based on
reading elf file. Expectation is that bl31.bin is in the same folder as
bl31.elf. It brings new flexibility to place TF-A to any address (DDR
included).

And also enable TEE generation also with TEE configuration.
Expecation is the same as above that tee.bin and tee.elf are in the same
folder.

User has to just define link to BL31/BL32 binary files and the rest should
be handled by the script.

TF-A and SecureOS can allocate the part of DDR for self but U-Boot is not
handling this configuration that the part of memory is reserved and
shouldn't be used by U-Boot. That's why read all reserved memory locations

The code was taken from commit 4a1b975d ("board: stm32mp1: reserve
