In order for cmd/cache.c to link we need to add dummy icache functions
to mirror the dummy dcache functions as well as another dcache flush
function.

Separate setjmp.h into an architecture independent part and an architecture
specific part. This simplifies moving from using struct jmp_buf_data
directly to using type jmp_buf in our code which is the C compliant way.

This returns a devicetree and updates a parameter with an error code.
Swap it, since this fits better with the way U-Boot normally works. It
also (more easily) allows leaving the existing pointer unchanged.

No yaks were harmed in this change, but there is a very small code-size
reduction.

For sifive, the OF_BOARD option must be set for the function to be
called, so there is no point in checking it again. Also OF_SEPARATE is
defined always.

This is mostly hidden in the background, but it is sometimes useful to
look at it. Add a function to allow this.

An address may be mapped twice and unmapped twice. Delete the mapping
only when the last user unmaps it.

Fix a missing comment while here.

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.

Use log_debug() instead of including the function name in the string.
Add one more debug for PCI.

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
which depends on dm/cmdc-working
