26af162ac8 arch: m68k: Implement relocation
Implement relocation for M68K. Perform all the updates in start.S
relocate_code in assemby, since it is a simple matter of traversing
the dynsym table and adding relocation offset - MONITOR_BASE to all
the items in that table. The necessity to deal with MONITOR_BASE is
a specific of M68K, where the ELF entry point is at offset 0x400,
which is the MONITOR_BASE, while TEXT_BASE is at offset 0 .

This also removes the one last user of NEEDS_MANUAL_RELOC, so that
could be finally cleaned up .

65cc0e2a65 global: Move remaining CONFIG_SYS_* to CFG_SYS_*
The rest of the unmigrated CONFIG symbols in the CONFIG_SYS namespace do
not easily transition to Kconfig. In many cases they likely should come
from the device tree instead. Move these out of CONFIG namespace and in
to CFG namespace.

ad5720a357 m68k: mcf: Remove overloading version_string
There is no need to overload version_string at the end of start.S files.
Common implementation of version_string should be fine.

941338725d common: Move relocate_code() to init.h
This is an init function so move it out of the common header. Avoid using
the typedef so that we don't have to include the global_data header file.

Also tidy up the function style in comments while we are here.

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.

5c928d0204 m68k: code reformatting for all start.S files
This patch is style-related only, to reformat all the start.S code,
actually not following a coherent style inside single files and
between different cpu start.S files.

Linux format has been respected, as
  - max line width at 80 columns
  - one 8 cols tab between asm instructions and operands
  - inline comments, where any, fixed at col 41

5044c9cc6c m68k: add malloc memory for early malloc

So CONFIG_SYS_GENERIC_GLOBAL_DATA has been undefined and
call to board_init_f_mem() is added for all cpu's.

09c2e90c11 unify version_string

version_string where possible. Some architectures use a special place
and therefore we provide U_BOOT_VERSION_STRING definition and a common
weak symbol version_string.

25ddd1fb0a Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated value
CONFIG_SYS_GBL_DATA_SIZE has always been just a bad workarond for not
being able to use "sizeof(struct global_data)" in assembler files.
Recent experience has shown that manual synchronization is not
reliable enough.  This patch renames CONFIG_SYS_GBL_DATA_SIZE into
GENERATED_GBL_DATA_SIZE which gets automatically generated by the
asm-offsets tool.  In the result, all definitions of this value can be
deleted from the board config files.  We have to make sure that all
files that reference such data include the new <asm-offsets.h> file.

No other changes have been done yet, but it is obvious that similar
changes / simplifications can be done for other, related macro
definitions as well.
