serial: a37xx: Reset whole UART when changing parent clock from TBG to XTAL
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.

arm: mvebu: turris_omnia: enable A385 watchdog before disabling MCU watchdog
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.

qemu: common: Fix build with update capsule
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:
make[1]: *** No rule to make target 'board/emulation/common/qemu_capsule.o', needed by 'board/emulation/common/built-in.o'. Stop.

Pull request for efi-2022-01-rc3-2
Test:
* fix pylint warnings
UEFI:
* disable interrupts before removing devices in ExitBootServices()
* implement poweroff in efi_system_reset() on sandbox
* allow booting via EFI even if some block device fails
Here efi_resister_disk() failed due to an error in the BTRFS implementation.
Move the logic to clear EFI_OS_INDICATIONS_FILE_CAPSULE_DELIVERY_SUPPORTED
to the rest of the capsule code.
If CONFIG_EFI_IGNORE_OSINDICATIONS=y, we should still clear the flag.
If OsIndications does not exist, we should not create it as it is owned by
the operating system.
Our algorithm for creating USB device paths may lead to duplicate device
paths which result in efi_disk_register() failing. Instead we should just
skip devices that cannot be registered as EFI block devices.
Fix a memory leak in efi_disk_add_dev() caused by the duplicate device
path.

efi: Call bootm_disable_interrupts earlier in efi_exit_boot_services
If we look at the path that bootm/booti take when preparing to boot the
OS, we see that as part of (or prior to calling do_bootm_states,
explicitly) the process, bootm_disable_interrupts() is called prior to
announce_and_cleanup() which is where udc_disconnect() /
board_quiesce_devices() / dm_remove_devices_flags() are called from. In
the EFI path, these are called afterwards. In efi_exit_boot_services()
however we have been calling bootm_disable_interrupts() after the above
functions, as part of ensuring that we disable interrupts as required
by the spec. However, bootm_disable_interrupts() is also where we go
and call usb_stop(). While this has been fine before, on the TI J721E
platform this leads us to an exception. This exception seems likely to
be the case that we're trying to stop devices that we have already
disabled clocks for. The most direct way to handle this particular
problem is to make EFI behave like the do_bootm_states() process and
ensure we call bootm_disable_interrupts() prior to ending up in
usb_stop().

efi_loader: startup the tpm device when installing the protocol
Due to U-Boot's lazy binding mentality the TPM is probed but not properly
initialized. The user can startup the device from the command line
e.g 'tpm2 startup TPM2_SU_CLEAR'. However we can initialize the TPM during
the TCG protocol installation, which is easier to use overall.

efi_loader: fix FinalEvents table if an EFI app invoked GetEventLog
As described in the TCG spec [1] in sections 7.1.1 and 7.1.2 the FinalEvent
table should include events after GetEventLog has been called. This
currently works for us as long as the kernel is the only EFI application
calling that. Specifically we only implement what's described in 7.1.1.
So refactor the code a bit and support EFI application(s) calling
GetEventLog. Events will now be logged in both the EventLog and FinalEvent
table as long as ExitBootServices haven't been invoked.

efi_loader: capsule: Record capsule result only if capsule is read
Record capsule update result only if the capsule file is
successfully read, because the capsule GUID is not sure when
the file can not be read or the file is not a capsule.
Without this fix, if user puts a dummy (non-capsule) file
under (ESP)EFI/UpdateCapsule, U-Boot causes a synchronous
abort.
This also fixes use-after-free bug of the 'capsule' variable.
