2189d5f1e8 Move strtomhz() to vsprintf.h
At present this function sits in its own file but it does not really
justify it. There are similar string functions in vsprintf.h, so move it
there. Also add the missing function comment.

Use the vsprintf.h include file explicitly where needed.

1b1d8c19f5 spl: fix linker size check off-by-one errors
This fixes SPL linker script size checks for 3 lds files where the size
checks were implemented as "x < YYY_MAX_SIZE".

Fix the size checks to be "x <= YYY_MAX_SIZE" instead.

2f41ade79e linker: Modify linker scripts to be more generic
Make use of "IMAGE_MAX_SIZE" and "IMAGE_TEXT_BASE" rather than
CONFIG_SPL_MAX_SIZE and CONFIG_SPL_TEXT_BASE.  This lets us re-use the
same script for both SPL and TPL.  Add logic to scripts/Makefile.spl to
pass in the right value when preprocessing the script.

93b283d49f ARM: CPU: arm926ejs: Consolidate cache routines to common file
Four different boards had different options for enabling cache
that were virtually all the same.  This consolidates these
common functions into arch/arm/cpu/arm926ejs/cache.c

This also has the positive side-effect of enabling cache on
the Davinci (da850) boards.

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.

3a649407a4 arm: Migrate SYS_THUMB_BUILD to Kconfig, introduce SPL_SYS_THUMB_BUILD
Today, we have cases where we wish to build all of U-Boot in Thumb2 mode for
various reasons.  We also have cases where we only build SPL in Thumb2 mode due
to size constraints and wish to build the rest of the system in ARM mode.  So
in this migration we introduce a new symbol as well, SPL_SYS_THUMB_BUILD to
control if we build everything or just SPL (or in theory, just U-Boot) in
Thumb2 mode.

f8a4826383 spl: arm: Make sure to include all of the u_boot_list entries
Starting with 96e5b03 we use a linker list for partition table
information.  However since we use this in SPL we need to make sure that
the SPL linker scripts include these as well.  While doing this, it's
best to simply include all linker lists to future proof ourselves.
