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.

f40ad66fa0 arch/sh: don't bring common/env_embedded.o into the link
The linker script for SuperH brings the .ppcenv and .ppcenvr section
of common/env_embedded.o into the .text section. However, the .ppcenv
section is only ever filled in by env_embedded.o when
CONFIG_SYS_USE_PPCENV is defined, but no platforms in mainline U-Boot
use this.

In addition, common/env_embedded.o is not always built (when you use
CONFIG_ENV_IS_NOWHERE for example), which causes the following build
failure:

Fixes:

  LD      u-boot
/home/thomas/sh4aeb-linux-musl/bin/sh4aeb-linux-ld.bfd: cannot find common/env_embedded.o

We fix this by no longer adding the .ppcenv and .ppcenvr sections from
common/env_embedded.o into the .text section.

90340c87e5 arch/sh: allow building in big-endian mode
The SuperH architecture allows to be run in either little or big
endian mode. Some SuperH SoCs get the little vs. big endian decision
through mode pins sampled at reset, so if big endian has been choosen
by HW designers, it cannot be easily changed.

Therefore, it makes sense to allow building U-Boot for SuperH in big
endian mode. To allow this, the only change needed is to adjust the
OUTPUT_FORMAT() in the linker script.

c1c3fe2307 env: Convert CONFIG_ENV_IS_IN... to a choice
At present we support multiple environment drivers but there is not way to
select between them at run time. Also settings related to the position and
size of the environment area are global (i.e. apply to all locations).

Until these limitations are removed we cannot really support more than one
environment location. Adjust the location to be a choice so that only one
can be selected. By default the environment is 'nowhere', meaning that the
environment exists only in memory and cannot be saved.

Also expand the help for the 'nowhere' option and move it to the top since
it is the default.

Finally add fpic compilation option to produce relocatable code.
Note that this requires to define CONFIG_NEEDS_MANUAL_RELOC for all
board files, also relocation support still has some limitations
(e.g. a developer should care not to overwrite the executing code or
memset() with zeroes not yet relocated data on malloc init etc.),
which may be fixed while switching to PIE.

Due to short investigation the architecture code is not ready for PIE
linking, this will require some manipulations with .dyn* sections.

9c141b2bd7 sh4: fix start.S by calling board_init_f() after first code relocation
Like on ARM platform keep the first code relocation from a U-boot
image storage to RAM at CONFIG_SYS_TEXT_BASE, then pass execution to a
generic board_init_f() with empty GD flags. If CONFIG_SYS_TEXT_BASE is
equal to a calculated by board_init_f() relocation address there will
be no more code and data copy, however it's worth to mention that the
first copy happens even if $pc on _start is the same as
CONFIG_SYS_TEXT_BASE, on practice this works without a problem.

Also note that _sh_start is renamed back to _start to correct
gd->mon_len calculation by setup_mon_len(), the opposite rename was
done in pre-generic board commit 2024b968ee ("sh: Fix build in start.S").

cdbb0cf8ec sh: add common dram_init() function for all boards
Generic board support assumes a different method of specifying
DRAM size on board, also it can be shared among all boards, notably
only sh7763rdp board has a custom legacy dram_init(), however
the difference is only in printing some additional information,
this feature can be removed.

b26d25072f sh: define entry point and reloc_dst inside a linker script
No functional change, concentrate linker script commands in one
place for convenience. Entry point is set to CONFIG_SYS_TEXT_BASE by
default on build, so this option can be omitted from being added to
the linker script.
