According to the MicroBlaze reference manual (xilinx2021.2/ug984/page-37):
"""
If an exception is caused by an instruction in a delay slot (that is,
ESR[DS]=1), the exception handler should return execution to
the address stored in BTR instead of the normal exception return
address stored in R17.
"""
Adjust the code to print the proper return address for delay slot
exceptions.

The switch statement in _hw_exception_handler() only covers the
rightmost 5 bits that encode the exception cause:
switch (state & 0x1f)
{
...
}
For this reason, the "0x1000" case will never be reached, because the 13th
bit was zeroed out. To fix this, move delay slot exception handling before
the switch statement (delay slot (DS) bit in Exception Status Register is
independent of the exception cause (EC)).

When building for a custom board, it is quite common to maintain a
private branch which include some defconfig and .dts files. But to
hook up those .dts files requires modifying a file "belonging" to
upstream U-Boot, the arch/*/dts/Makefile. Forward-porting that branch
to a newer upstream then often results in a conflict which, while it
is trivial to resolve by hand, makes it harder to have a CI do "try to
build our board against latest upstream".
The .config usually includes information on precisely what .dtb(s) are
needed, so to avoid having to modify the Makefile, simply add the
files in (SPL_)OF_LIST to dtb-y.
A technicality is that (SPL_)OF_LIST is not always defined, so rework
the Kconfig symbols so that (SPL_)OF_LIST is always defined (when
(SPL_)OF_CONTROL), but only prompted for in the cases which used to be
their "depends on".
nios2 and microblaze already have something like this in their
dts/Makefile, and the rationale in commit 41f59f6853 is similar to
the above. So this simply generalizes existing practice. Followup
patches could remove the logic in those two makefiles, just as there's
potential for moving some common boilerplate from all the
arch/*/dts/Makefile files to the new scripts/Makefile.dts.

Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

Unlike Linux, nothing about errno.h is arch-specific in U-Boot.
As you see, all of arch/${ARCH}/include/asm/errno.h is just a
wrapper of <asm-generic/errno.h>. Actually, U-Boot does not
export headers to user-space, so we just have to care about the
consistency in the U-Boot tree.
Now all of include directives for <asm/errno.h> are gone.
Deprecate <asm/errno.h>.

There are already two FIT options in Kconfig but the CONFIG options are
still in the header files. We need to do a proper move to fix this.
Move these options to Kconfig and tidy up board configuration:
CONFIG_FIT
CONFIG_OF_BOARD_SETUP
CONFIG_OF_SYSTEM_SETUP
CONFIG_FIT_SIGNATURE
CONFIG_FIT_BEST_MATCH
CONFIG_FIT_VERBOSE
CONFIG_OF_STDOUT_VIA_ALIAS
CONFIG_RSA
Unfortunately the first one is a little complicated. We need to make sure
this option is not enabled in SPL by this change. Also this option is
enabled automatically in the host builds by defining CONFIG_FIT in the
image.h file. To solve this, add a new IMAGE_USE_FIT #define which can
be used in files that are built on the host but must also build for U-Boot
and SPL.
Note: Masahiro's moveconfig.py script is amazing.

fdtgrep requires /chosen node to be specified or at least more nodes which
stays in DTS to generate output.

board_init_f_mem() alters the C runtime environment's
stack it is actually already using. This is not a valid
behaviour within a C runtime environment.
Split board_init_f_mem into C functions which do not alter
their own stack and always behave properly with respect to
their C runtime environment.

'extern inline' is not portable across various C standards. To ensure
compatiblity with various standards/compilers change the functions to
static inline. This is a portable construct and serves as a comparable
definition to 'extern inline' from the gnu90 standard.
Additionally remove the function prototypes as they are not required due
to the functions being declared static and functions are correctly
ordered based on dependence.

After consulting with some of the SPDX team, the conclusion is that
Makefiles are worth adding SPDX-License-Identifier tags too, and most of
ours have one. This adds tags to ones that lack them and converts a few
that had full (or in one case, very partial) license blobs into the
equivalent tag.

By making the board selections optional, every defconfig will include
the board selection when running savedefconfig so if a new board is
added to the top of the list of choices the former top's defconfig will
still be correct.
