image: Add IH_OS_TEE for TEE chain-load boot
This patch adds a new type IH_OS_TEE. This new OS type will be used for
chain-loading to Linux via a TEE.
With this patch in-place you can generate a bootable OPTEE image like this:
mkimage -A arm -T kernel -O tee -C none -d tee.bin uTee.optee
where "tee.bin" is the input binary prefixed with an OPTEE header and
uTee.optee is the output prefixed with a u-boot wrapper header.
This image type "-T kernel -O tee" is differentiated from the existing
IH_TYPE_TEE "-T tee" in that the IH_TYPE is installed by u-boot (flow
control returns to u-boot) whereas for the new IH_OS_TEE control passes to
the OPTEE firmware and the firmware chainloads onto Linux.
Andrew Davis gave the following ASCII diagram:
IH_OS_TEE: (mkimage -T kernel -O tee)

CONFIG_OPTEE_LOAD_ADDR is used to tell u-boot where to load the OPTEE

We need to pull this value out of u-boot in order to produce an IMX IVT/CSF

have CONFIG_OPTEE_LOAD_ADDR appear in u-boot.cfg.

watchdog: omap_wdt: improve watchdog reset path
Remove busy looping during watchdog reset.
Each polling of W_PEND_WTGR bit ("finish posted

on BeagleBone Black board. Current U-Boot code
has watchdog resets in random places and often
there is situation when watchdog is reset
few times in a row in nested functions.
This adds extra delays and slows the whole system.
Instead of polling W_PEND_WTGR bit, we skip
watchdog reset if the bit is set. Anyway, watchdog
is in the middle of reset *right now*, so we can
just return.
This noticeably increases performance of the

mach-stm32: Use default memory map as background region
On linux kernel side, on STM32F7 and STM32H7 SoCs, DMA requires
uncachable regions. These regions are defined in DT.
Since kernel linux v4.15, on ARMv7-M Cortex, kernel is able
to configure MPU regions depending on DT settings.
As kernel is able to configure MPU, this allows to remove
MPU region settings in bootloader.
On Cortex M processors, MPU allows to use a default memory map.
(see B3.5.4 MPU Control Register, MPU_CTRL in
https://developer.arm.com/products/architecture/m-profile/docs/ddi0403/latest/armv7-m-architecture-reference-manual)
Use the default memory map as background region for all STM32 SoCs
family with an additional MPU region corresponding to the SDRAM area.
