The current name is inconsistent with SPL which uses CONFIG_SPL_TEXT_BASE
and this makes it imposible to use CONFIG_VAL().

Move this out of the common header and include it only where needed. In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly. Finally, we have a few
cases where we did not need to include <asm/global_data.h> at all, so
remove that include.

At present this function copies U-Boot from the last 1MB of ROM. This is
not the right way to do it. Instead, the binman symbol should provide the
location.
But in any case the code should live in the caller,
spl_board_load_image(), so that the 64-bit jump function can be used
elsewhere. Move it.

These functions do not use driver model but are fairly widely used in
U-Boot. But it is not clear that they will use driver model anytime soon,
so we don't want to label them as 'legacy'.
Move them to a new irq_func.h header file. Avoid the name 'irq.h' since it
is widely used in U-Boot already.

These functions belong in cpu_func.h. Another option would be cache.h
but that code uses driver model and we have not moved these cache
functions to use driver model. Since they are CPU-related it seems
reasonable to put them here.
Move them over.

At present we call spl_init() before identifying the CPU. This is not a
good idea - e.g. if bootstage is enabled then it will try to set up the
timer which works better if the CPU is identified.
Put explicit code at each entry pointer to identify the CPU.

This image loader works on systems where the flash is directly mapped to
the last part of the 32-bit address space. On recent Intel systems (such
as apollolake) this is not the case.
Reduce the priority of this loader so that another one can override it.
While we are here, rename the loader to BOOT_DEVICE_SPI_MMAP since
BOOT_DEVICE_BOARD is not very descriptive.

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.

Print the banner a little later (after the CPU is ready) to avoid this.
