3f1d79932a test: Allow saving and restoring the bloblist
Tests which create a new bloblist overwrite the existing one in sandbox.
Provide a flag for tests to declare this behaviour. Save and restore the
bloblist pointer so that other tests remain unaffected.

Note that when sandbox is running normally, the bloblist has been
relocated to high in memory. The existing bloblist tests create a new
bloblist low in memory, so they do not conflict.

Correct a build error on coreboot by using accessors for gd->bloblist:

Simon Glass <sjg@chromium.org> says:

6abd992ada board_f: Add a new struct to hold pre-relocation info
Quite a few of the members of struct global_data are only used before
reloction, or have little meaning afterwards, yet they hang around in
struct global_data for the lifetime of U-Boot. This uses up precious
pre-relocation SRAM on many boards.

To help with this, start a new struct which exists only before
relocation. Move new_fdt into this new struct. Drop the display of it
in the 'bdinfo' command as it is probably not very useful.

Note that the field does not exist in SPL builds.

3d6531803e bloblist: Support initing from multiple places
Typically the bloblist is set up after the devicetree is present. This
makes sense because bloblist may use malloc() to allocate the space it
needs.

However sometimes the devicetree itself may be present in the bloblist.
In that case it is at a known location in memory so we can init the
bloblist very early, before devicetree.

Add a flag to indicate whether the bloblist has been inited. Add a
function to init it only if needed. Use that in the init sequence.

15a23b6f16 dm: core: Allow marking driver model as dead
On x86 devices we use CAR (Cache-As-RAM) to hold the malloc() region in
SPL, since SDRAM is not set up yet. This means that driver model stores
its tables in this region.

When preparing to jump from SPL to U-Boot proper, we must disable CAR, so
that the CPU can uses the caches normally. This means that driver model
tables become inaccessible. From there until we jump to U-Boot proper, we
must avoid using driver model.

This is only a problem on boards which operate this way, for example
chromebook_link64

Add a flag to indicate that driver model is dead and should not be used.
It can be used in SPL to avoid hanging the machine.

50128aeb0f cyclic: get rid of cyclic_init()
Currently, we must call cyclic_init() at some point before
cyclic_register() becomes possible. That turns out to be somewhat
awkward, especially with SPL, and has resulted in a watchdog callback
not being registered, thus causing the board to prematurely reset.

We already rely on gd->cyclic reliably being set to NULL by the asm
code that clears all of gd. Now that the cyclic list is a hlist, and
thus an empty list is represented by a NULL head pointer, and struct
cyclic_drv has no other members, we can just as well drop a level of
indirection and put the hlist_head directly in struct
global_data. This doesn't increase the size of struct global_data,
gets rid of an early malloc(), and generates slightly smaller code.

But primarily, this avoids having to call cyclic_init() early; the cyclic
infrastructure is simply ready to register callbacks as soon as we
enter C code.

We can still end up with schedule() being called from asm very early,
so we still need to check that gd itself has been properly initialized
[*], but once it has, gd->cyclic_list is perfectly fine to access, and
will just be an empty list.

As for cyclic_uninit(), it was never really the opposite of
cyclic_init() since it didn't free the struct cyclic_drv nor set
gd->cyclic to NULL. Rename it to cyclic_unregister_all() and use that
in test/, and also insert a call at the end of the board_init_f
sequence so that gd->cyclic_list is a fresh empty list before we enter
board_init_r().

A small piece of ugliness is that I had to add a cast in
cyclic_get_list() to silence a "discards 'volatile' qualifier"
warning, but that is completely equivalent to the existing handling of
the uclass_root_s list_head member.

[*] I'm not really sure where we guarantee that the register used for
gd contains 0 until it gets explicitly initialized, but that must be
the case, otherwise testing gd for being NULL would not make much sense.
