70c68712ef microblaze: drop CONFIG_SYS_RESET_ADDRESS macro
Microblaze is one the last two users of the CONFIG_SYS_RESET_ADDRESS
macro (the other is arch/powerpc/cpu/mpc8xx/cpu.c, but the macro is not
defined anywhere in powerpc code, so it should be removed there too).

Replace CONFIG_SYS_RESET_ADDRESS usage in start.S with
CONFIG_SYS_TEXT_BASE. If the reset address should really be
user-configurable, a new Kconfig option could be added.

b3fe1e8ff3 microblaze: spl: add board_boot_order() implementation
Microblaze has three boot modes defined in microblaze/include/asm/spl.h,
but only booting from NOR flash is currently useable. Add a custom
board_boot_order() implementation so that RAM and SPI boot modes can also
be selected if the corresponding load-image support is present.

edf0f9b15e microblaze: u-boot.lds: replace __end symbol with _end
board_fdt_blob_setup() uses the _end symbol to find the dtb in the non-spl
case. In order to allow microblaze builds to compile successfully with
CONFIG_OF_SEPARATE, the _end symbol must be defined. Align microblaze with
the other architectures and use _end symbol rather than __end to mark the
end of the u-boot binary.

Move this out of the common header and include it only where needed.  In

cases where we did not need to include <asm/global_data.h> at all, so

9c2aa7e707 microblaze: Enable GCC garbage collector for full U-Boot
GCC's garbage collector works for Microblaze for quite a long time but none
has enabled it.
The same change has be done for example by commit fac4790491 ("arc:
Eliminate unused code and data with GCC's garbage collector").

Before:
   text	   data	    bss	    dec	    hex	filename
 588760	  33592	  39192	 661544	  a1828	u-boot

After:
   text	   data	    bss	    dec	    hex	filename
 504504	  32164	  38608	 575276	  8c72c	u-boot

Which saves almost 15% of memory footprint.

Also group symbols/functions to proper section.

Timer needs to be converted to DM but as of now it can't be called so
early because intc controller is not ready. Call it later in board_r.c.
Before this patch timer_init is called twice which is wrong.
The patch is blocking initialization before relocation.

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.

b529993e02 spl: add hierarchical defaults for SPL_LDSCRIPT
With SPL_LDSCRIPT moved to Kconfig (and this being a 'string' config
node), all the lingering definitions in header files will cause
warnings/errors due to the redefinition of the configuration item.

As we don't want to pollute the defconfig files (and values should
usually be identical for entire architectures), the defaults are moved
into Kconfig.  Kconfig will always pick the first default that
matches, so please keep these values at the end of each file (to allow
any board-specific Kconfig, which will be included earlier) to
override with an unconditional default setting.

Make SPL and (the full) U-Boot stage use independent SYS_MALLOC_F_LEN,
so the size of pre-relocation malloc pool can be configured memory

Commit e2f88dfd2d ("libfdt: Introduce new ARCH_FIXUP_FDT option")

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.
