So far unmapping has not been implemented. This means that if one test
maps a pointer to an address with map_sysmem(), then a second test can
use that same pointer, by mapping the address back to a pointer with
map_to_sysmem(). This is not really desirable, even if it doesn't
cause any problems at the moment.
Implement unmapping, to clean this up.

Since the removal of OF_HOSTFILE logic in board_fdt_blob_setup(), the
logic for obtaining the DT is handled in the OF_BOARD option. If a
devicetree comes from a bloblist it is immediately overwritten by this
function.
Fix this by skipping the function if a devicetree is already present.
This is sort-of a fix for e7fb7896 ("sandbox: Remove OF_HOSTFILE") but
it has only come to light since bloblist was added, so I have not added
a Fixes tag.
Unfortunately it is not possible to report the correct FDT source with
the current code. It might be best to use an error-return code for
board_fdt_blob_setup() so that an error can be reported if the board
does not provide the DT.

Simon Glass <sjg@chromium.org> says:
This series continues refactoring the bootm code to allow it to be used
with CONFIG_COMMAND disabled. The OS-handling code is refactored and
a new bootm_run() function is created to run through the bootm stages.
This completes the work.
A booti_go() function is created also, in case it proves useful, but at
last for now standard boot does not use this.
This is cmdd (part d of CMDLINE refactoring)
It depends on dm/bootstda-working

With sandbox, U-Boot can be run without a device tree (i.e. no -d or -T

With a recent change this causes an error due to the missing '/binman'

Add this node to avoid the problem, as well as a test that U-Boot can

OF_HOSTFILE is used on sandbox configs only. Although it's pretty
unique and not causing any confusions, we are better of having simpler
config options for the DTB.
So let's replace that with the existing OF_BOARD. U-Boot would then
have only three config options for the DTB origin.
- OF_SEPARATE, build separately from U-Boot
- OF_BOARD, board specific way of providing the DTB
- OF_EMBED embedded in the u-boot binary(should not be used in production

At present dm/device.h includes the linux-compatible features. This

One of these is malloc.h which we thus end up including in every file in

which needs to use the system malloc() in some files.

In sandbox, longjmp returns to itself in an endless loop because
os_longjmp() calls into longjmp() which is provided by U-Boot which
again calls os_longjmp().
Setjmp on the other hand must not return because otherwise the
return freees up stack elements that we need during longjmp().
The only straight forward fix that doesn't involve nasty hacks I
could find is to directly link against the system setjmp/longjmp
implementations. That means we just provide the compiler with
hints that the symbol will be available and actually fill them
out with versions from libc.
This approach should be reasonably platform agnostic

At present map_sysmem() maps an address into the sandbox RAM buffer,
return a pointer, while map_to_sysmem() goes the other way.
The mapping is currently just 1:1 since a case was not found where a more
flexible mapping was needed. PCI does have a separate and more complex
mapping, but uses its own mechanism.
However this arrange cannot handle one important case, which is where a
test declares a stack variable and passes a pointer to it into a U-Boot
function which uses map_to_sysmem() to turn it into a address. Since the
pointer is not inside emulated DRAM, this will fail.
Add a mapping feature which can handle any such pointer, mapping it to a
simple tag value which can be passed around in U-Boot as an address.

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.
