tpm_tis_remove() leads to calling tpm_tis_ready() with the IO region
unmapped and chip->locality == -1 (locality released). This leads to a
crash in mmio_write_bytes().
The patch implements these changes:
tpm_tis_remove(): Unmap the IO region after calling tpm_tis_cleanup().
tpm_tis_cleanup(): Request locality before IO output and releasing
locality.

Firmwares before U-Boot may be capable of doing tpm measurements
and passing them to U-Boot in the form of eventlog. However there
may be scenarios where the firmwares don't have TPM driver and
are not capable of extending the measurements in the PCRs.
Based on TCG spec, if previous firnware has extended PCR's, PCR0
would not be 0. So, read the PCR0 to determine if the PCR's need
to be extended as eventlog is parsed or not.

Platforms may have support to measure their initial firmware components
and pass the event log to u-boot. The event log address can be passed
in property tpm_event_log_addr and tpm_event_log_size of the tpm node.
Platforms may choose their own specific mechanism to do so. A weak
function is added to check if even log has been passed to u-boot
from earlier firmware components. If available, the eventlog is parsed
to check for its correctness and further event logs are appended to the
passed log.

Sometimes UART stops transmitting characters after UART clock is changed
back to XTAL. In this state UART fifo is always full. Kernel during early
boot wants to print output on UART and is waiting for non-empty UART fifo.
Which leads to CPU hangup without any (debug) output on UART.
Marvell Armada 3700 Functional Specifications says that for programming
fractional divisor registers it is required to disable UART, enable
loopback mode, reset fifos, program registers, disable loopback mode,
release reset of fifos and enable UART.
But these steps do not fix above mentioned issue that UART hangup. Also
gating UART clock does not help. And even resetting UART state machines do
not help.
Experiments showed that UART fifo is unblocked after board is being reset
(during board reset UART HW transmit UART fifo even CPU is not executing
kernel/bootloader anymore).
And another experiments showed that same workaround can be achieved also
by external reset of UART HW (without need to reset board).
So do not implement any of "Marvell recommended" steps from Functional
Specifications as they do not work. And rather prior changing parent clock
back to XTAL, do external reset of UART HW. This operation also resets all
UART registers, so basically it also sets UART clock to default, which is
XTAL. It is unknown why UART hangups and enters such broken state.

Commit aeb0ca64dbb5 ("arm: mvebu: turris_omnia: disable MCU watchdog in
SPL when booting over UART") disabled MCU watchdog when booting over
UART to ensure that watchdog does not reboot the board before UART
transfer finishes.
But if UART transfer fails for some reason, or if U-Boot binary crashes,
then board hangs forever as there is no watchdog running which could
reset it.
To fix this issue, enable A385 watchdog with very high timeout before
disabling MCU watchdog to ensure that even slow transfer can finish
successfully before watchdog timer expires and also to ensure that if
board hangs for some reason, watchdog will reset it.
Omnia's MCU watchdog has fixed 120 seconds timer and it cannot be
changed (without updating MCU firmware). A385 watchdog by default uses
25 MHz input clock and so the largest timeout value (2^32-1) can be
just 171 seconds. But A385 watchdog can be switched to use NBCLK (L2) as
input clock (on Turris Omnia it is 800 MHz clock) and in this case final
watchdog clock frequency is calculated as:
freq = NBCLK / 2 / (2 ^ R)
So A385 watchdog on Turris Omnia can be configured to at most 1374
seconds (about 22 minutes). We set it to 10 minutes, which should be
enough even for bigger U-Boot binaries or slower UART transfers.
Both U-Boot and Linux kernel, when initializing A385 watchdog, switch
watchdog timer to 25 MHz input clock, so usage of NBCLK input clock in
U-Boot SPL does not cause any issues.

The common emulation Makefile has a dependency on a non-existent
qemu_capsule.o when building with support for capsule update enabled
(CONFIG_EFI_RUNTIME_UPDATE_CAPSULE=y).
The code which was in qemu_capsule.c has been completely moved to
lib/efi_loader/efi_capsule.c by commit 7a6fb28c8e4b ("efi_loader: capsule:
add back efi_get_public_key_data()").
Remove the false dependency.
This fixes the following build error:

At present the collection function used by pytest is quite strict on the
naming of the functions it detects. In particular it requires the name of
the test to be repeated in the function name.
This is not enforced anywhere else, but instead the tests are silently
omitted from the pytest run. This affects a few dozen tests.
The rule does not seem to have any particular purpose. Relax it, so that
all tests that use the UNIT_TEST() macro will run, regardless of the name
of the test function.

At present we support reading a string list a string at a time. Apart
from being inefficient, this makes it impossible to separate reading of
the devicetree into the of_to_plat() method where it belongs, since any
code which needs access to the string must read it from the devicetree.
Add a function which returns the string property as an array of pointers
to the strings, which is easily used by clients.
