When calling mmu_map_region() we might add a table from tlb_fillptr.
Usually this would just clobber the emergency table, so put the
emergency table first to avoid this.

FIXME: this should probably be a change to default setup_pgtables_all()
as well?

The fastboot tool will always wrap anything that isn't an Android boot
image in a boot image header, work around this by letting you boot an
image by running "fastboot stage BIN". Useful for booting FIT images.

Add a defconfig and fit source file for flashing U-Boot to the TZ
partition and then booting a FIT image over fastboot. This is useful for
doing TF-A/OP-TEE development over CDBA.

Enable support for running U-Boot in EL3. This requires skipping the
psci call, and for now we must also keep dcache off (at least on
rb3gen2).

U-Boot already supporting booting TF-A/OP-TEE/U-Boot all from a FIT
image, but only in SPL mode. Now that the code to do this has been moved
out of SPL, we can re-use it to enable booting this way from full fat
U-Boot.

This may be useful for development (particularly on boards that lack
SPL support) as it makes iterating on TF-A changes easy by allowing the
FIT image to be loaded via fastboot or some other mechanism.

Under some conditions it's possible to hit the null condition here like
when running with OF_LIVE and using the ofnode API before
initr_of_live() is called. There is very little null
checking for this in the FDT framework, so returning null here can
result in weird null pointer conditions.

Instead let's return the control FDT in the fallback case, this is
usually what the user was expecting.

We already build arm64 images with frame pointers. Let's finally make
use of them in tandem with the new symbol lookup support by unwinding
the stack when an exception occurs, producing a backtrace similar to
those emitted by Linux.

In addition, introduce a dedicated unwind_stack() function which can be
called from anywhere to print a backtrace.

This is mostly a port of the Xen hypervisor implementation. The U-Boot
binary is built as normal, then its symbol table is fed into
tools/symbols to generate an optimised lookup table. U-Boot is rebuilt
with the symbol table and handling code in lib/symbols.c.

Based on code from Xen at

There was some very old code floating around for decoding symbols, it's
incomplete and is never built. Remove it so we can add a new
implementation.

This reverts commit dbd5ad88.

It may be the case that MMC support is enabled even though the board
we're booting on doesn't have any MMC devices. Move the print over to
the print_mmc_devices() function where we can only print it if we
actually have MMC devices.

Some dt-binding headers mask the upstream ones which can lean to build
failures, or worse: super weird bugs if they get out of sync.

Remove these headers so our devicetree and headers will both be in sync
with upstream.

Add a small utility for displaying some information about U-Boot and the
hardware it's running on in a similar fashion to the popular neofetch
tool for Linux [1].

While the output is meant to be useful, it should also be pleasing to
look at and perhaps entertaining. The ufetch command aims to bring this
to U-Boot, featuring a colorful ASCII art version of the U-Boot logo.
