f3035cf299 microblaze: Unify Linux bootm process
Record two bootstages and add "Starting kernel" message to have standard

0905046050 microblaze: Switch to generic bootm implementation
There is no reason to use private code for standard bootm command.
Current implementation is also broken and don't support image relocation
properly. Switching to generic bootm implementation is fixing these issues.

cmdline and bdt bootm subcommands are returning -1 because they are not
implemented.

Similar change was done long time ago by for example commit 2bb5b63879
("MIPS: bootm: rework and fix broken bootm code")

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
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.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

4280342adb fdt: Implement weak arch_fixup_fdt()
Only ARM and in some configs MIPS really implement arch_fixup_fdt().
Others just use the same boilerplate which is not good by itself,
but what's worse if we try to build with disabled CONFIG_CMD_BOOTM
and enabled CONFIG_OF_LIBFDT we'll hit an unknown symbol which was
apparently implemented in arch/xxx/lib/bootm.c.

Now with weak arch_fixup_fdt() right in image-fdt.c where it is
used we get both items highlighted above fixed.

63c0941726 libfdt: replace ARCH_FIXUP_FDT with ARCH_FIXUP_FDT_MEMORY
Commit e2f88dfd2d ("libfdt: Introduce new ARCH_FIXUP_FDT option")
allows us to skip memory setup of DTB, but a problem for ARM is that
spin_table_update_dt() and psci_update_dt() are skipped as well if
CONFIG_ARCH_FIXUP_FDT is disabled.

This commit allows us to skip only fdt_fixup_memory_banks() instead
of the whole of arch_fixup_fdt().  It will be useful when we want to
use a memory node from a kernel DTB as is, but need some fixups for
Spin-Table/PSCI.

73223f0e1b Kconfig: Move CONFIG_FIT and related options to Kconfig
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.

983c72f479 Clarify bootm OS arguments
At present the arguments to bootm are processed in a somewhat confusing
way. Sub-functions must know how many arguments their calling functions
have processed, and the OS boot function must also have this information.
Also it isn't obvious that 'bootm' and 'bootm start' provide arguments in
the same way.

Adjust the code so that arguments are removed from the list before calling
a sub-function. This means that all functions can know that argv[0] is the
first argument of which they need to take notice.
