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.

We have a large number of places where while we historically referenced
gd in the code we no longer do, as well as cases where the code added
that line "just in case" during development and never dropped it.

U-Boot
Some platforms have very limited SRAM to run SPL code, so there may
not be the same amount space for a malloc pool before relocation in
the SPL stage as the normal U-Boot stage.
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
space independently.

At present fdt blob or argument address being passed to kernel is fixed at
compile time using macro CONFIG_SYS_SPL_ARGS_ADDR. FDT blob from
different media like nand, nor flash are copied to the address pointed
by the macro.
The problem is, it makes args/fdt blob compulsory to copy which is not required
in cases like for NOR Flash. This patch removes this limitation.

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.

This patch has some parts connected together:
- Use _gd in bss section which is automatically cleared
Location at SPL_MALLOC_END wasn't cleared at all
- Use MALLOC_F_LEN(early alloc) instead of FULL MALLOC
(mem_malloc_init is not called at all)
- Simplify malloc and stack init.
At the end of SPL addr is malloc area and below is stack

Refactor linker-generated array code so that symbols
which were previously linker-generated are now compiler-
generated. This causes relocation records of type
R_ARM_ABS32 to become R_ARM_RELATIVE, which makes
code which uses LGA able to run before relocation as
well as after.
Note: this affects more than ARM targets, as linker-
lists span possibly all target architectures, notably
PowerPC.

The interrupt acknowledge action have to run after the
registered interrupt handler. So we have a chance to
bear out the corresponding interrupt request in the
corresponding controller hardware.
With this reordering, we optain a proper interrupt
handling for level triggered interrupt sources -- for
example the new axi_timer v1.02.a introduced in ISE 13.2.
