Add support for jumping to Linux kernel through OPTEE-OS on ARMv7a.
This is only supported if U-Boot runs in PL1 secure. This change adds
two components, one is fitImage OPTEE-OS loadable handler, which makes
a note of OPTEE-OS being loaded and stores the load address for later
jump to it. The second part is the actual jump to Linux through OPTEE-OS.
The jump through OPTEE-OS requires set up of multiple CPU registers, r1
and r2 are passed through, r0 and r3 have to be set to 0, lr is set to
Linux kernel entry point. This setup is done by new assembler function
boot_jump_linux_via_optee().

The boot_jump_linux_via_optee() also includes STM32MP13xx late TZC
configuration write, this cannot be moved easily, hence the ifdef.

Prasad KaleandTom Rini c488907f91 Invalidate cached FAT device upon boot error
When spl boot device list has multiple FAT devices, any previousely
registered FAT device should be deregistered before registering
next FAT boot device, otherwise the function may not attempt boot
from next FAT device.One of the situations where this issue can be
observed is when the boot device list has two FAT partitions of a
memory device and if booting fails on first partition (because of
file or partition related errors), boot from next partition actually
gets attempted on previous boot device only, as the previous device
has remained marked as registered. Call the function that invalidates
cached boot device in case of failure in booting from current FAT
boot device.

Michael WalleandTom Rini 52442205d3 common/spl: fix endless loop in spl_fit_append_fdt()
Technically, commit 24bf44cf88 ("spl: fit: Do not fail immediately if
an overlay is not available") introduced that regression as the code
will never advance if spl_fit_get_image_name() will return an error. But
at that time, spl_fit_get_image_node() was used in spl_fit_append_fdt()
which calls fdt_subnode_offset() to get the image node. And I presume
the commit was about the latter failing gracefully and trying the next
one.

But with commit b13eaf3bb4 ("spl: fit: Add board level function to
decide application of DTO") that behavior changed and the loop in
spl_fit_append_fdt() no longer uses spl_fit_get_image_node() but
spl_fit_get_image_name() directly. Thus it doesn't make any sense to not
break the loop if that fails.

Also, the original use case of commit 24bf44cf88 ("spl: fit: Do not
fail immediately if an overlay is not available") is preserved because
spl_subnode_offset() is now called within the loop and errors are
handled gracefully (and advancing the index).

Jonas KarlmanandTom Rini 32ead3c1ba Revert "power: regulator: Add vin-supply for GPIO and Fixed regulators"
Rockchip boards may depend on a working MMC regulator in SPL to
successfully load FIT payload from MMC. Typically, these boards only
include the vmmc-supply regulator and not its vin-supply in SPL control
FDT.

The commit f98d812e53 ("power: regulator: Add vin-supply for GPIO and
Fixed regulators") breaks loading FIT from MMC in SPL on some of these
boards due to now requiring the vin-supply to be included in the SPL
control FDT.

The commit also strangely enables any found vin-supply in
regulator_common_of_to_plat() and not when a regulator is enabled or as
part of regulator_autoset().

Revert the commit to fix FIT loading in SPL on broken boards.

If a board needs to have its vin-supply enabled, two options come to
mind:

- Add regulator-always-on prop to the regulator in the -u-boot.dtsi for
  any board.

- Implement full support for reference counting of regulators and then
  update the regulator-uclass to enable any found vin-supply when a
  regulator is enabled.

This reverts commit f98d812e53.

Kaustabh ChakrabortyandTom Rini c9b43591ea armv8: implement workaround for broken CNTFRQ_EL0 value
In devices where the U-Boot is used as a secondary bootloader, we rely
on the device's primary bootloader to implement CNTFRQ_EL0. However,
this reliance may lead to a non-functional timer in broken firmware.

For instance, some versions of Samsung's S-Boot don't implement it. It's
also not possible to set it in the U-Boot, because it's booted in a lower
exception level. CNTFRQ_EL0 is reported to be 0.

Use gd->arch.timer_rate_hz to override the queried value if set. This
setting needs to be done in the board file, preferrably in timer_init().
This feature is present only when the CONFIG_ARMV8_CNTFRQ_BROKEN is
enabled.

Frieder SchrempfandFabio Estevam 5b4d3c8171 imx: kontron-sl-mx6ul: Add support for reading HW UIDs
The factory provides a CPU UID in the OTPs and the SoM module
and the carrier board might provide additional UIDs in the GP
registers of the OTPs. Load these values in the following order
and create a serial number string:

* Board UID (GP2)
* SoM UID (GP1)
* CPU UID (UNIQUE_ID)

The string is stored in the "serial#" env variable and
exported to Linux. Further this prints the used UID to the
console which looks like this

  ID:    0042152331 (Board)

or:

  ID:    0030124840 (SoM)

Frieder SchrempfandFabio Estevam f00b09abbf imx: kontron: Add common function to get HW UIDs from OTPs
The factory provides a CPU UID in the OTPs and the SoM module
and the carrier board might provide additional UIDs in the GP
registers of the OTPs.

Provide a common function to load UIDs from arbitrary OTP
registers and generate a serial number string that is saved
in the "serial#" env variable.

Frieder SchrempfandFabio Estevam 0089270b45 imx: kontron-sl-mx6ul: Enable CONFIG_BOARD_LATE_INIT to fix auto fastboot
Recently code was added in board_late_init() to autostart fastboot
in case of booting from USB OTG. This change was ineffective as
enabling CONFIG_BOARD_LATE_INIT got lost during upstreaming.

Frieder SchrempfandFabio Estevam 0358408104 imx: kontron-sl-mx8mm: Adjust offset for U-Boot proper in case of eMMC fastboot
The image offset on SD/MMC devices is 33 KiB, except for eMMC boot if
fastboot is enabled. In this case it is 1 KiB. In order to make the
the bootloader universal, check the fastboot OTP boot fuse and adjust
the offset.
