A compressed booti image relies on the compression-format's header at
the start to indicate which compression algorithm is used.
We don't support this elsewhere in U-Boot, so assume that a compressed
file is always a booti file. Once it is compressed, a check is made to
make sure that it actually is.
Simplify the implementation by adding a new function which returns the
booti image-type if compression is detected.

At present the booti format is handled separately, in its own command.
Provide a way to boot uncompressed booti images within the bootm code,
so that eventually we can boot these images without CONFIG_CMDLINE
Update bootm_init() to attach the images for all formats which use them.
Add some debugging while we are here.

lmb_reserve() is just calling lmb_reserve_flags() with LMB_NONE.
There's not much we gain from this abstraction.
So let's remove the latter, add the flags argument to lmb_reserve()
and make the code a bit easier to follow.

The current LMB API's for allocating and reserving memory use a
per-caller based memory view. Memory allocated by a caller can then be
overwritten by another caller. Make these allocations and reservations
persistent using the alloced list data structure.
Two alloced lists are declared -- one for the available(free) memory,
and one for the used memory. Once full, the list can then be extended
at runtime.

USB is stopped using driver model now, in dm_remove_devices_flags() in
announce_and_cleanup() at the top of this file.
The usb_stop() call actually unbinds devices.
When a USB device is unbound, it causes any bootflows attached to it to
be removed, via a call to bootdev_clear_bootflows() from
bootdev_pre_unbind(). This obviously makes it impossible to boot the
bootflow.
However, when booting a bootflow that relies on USB, usb_stop() is
called, which unbinds the device. At that point any information
attached to the bootflow is dropped.
This is quite risky since the contents of freed memory are not
guaranteed to remain unchanged. Depending on what other options are
done before boot, a hard-to-find bug may crop up.
Drop the call to this old function.
Leave the netconsole call there, since this needs conversion to
driver model.

commit 97707f12fdab ("tpm: Support boot measurements") moved out code
from the EFI subsystem into the TPM one to support measurements when
booting with !EFI.
Those were moved directly into the TPM subsystem and in the tpm-v2.c
library. In hindsight, it would have been better to move it in new
files since the TCG2 is governed by its own spec, it's overeall cleaner
and also easier to enable certain parts of the TPM functionality.
So let's start moving the headers in a new file containing the TCG
specific bits.

The PC client spec [0], doesn't describe measurements for DTBs. It does
describe what do to for ACPI tables though.
There is a description for ACPI in 3.3.4.1 PCR[0] – SRTM, POST BIOS,
and Embedded Drivers and they explicitly mention ACPI in there. There's
no mention of ACPI in 3.3.4.2 PCR[1] – Host Platform Configuration.
However, in Figure 6 -- PCR Mapping of UEFI Components ACPI is shown
in PCR1. The general description also mentions PCR0 is for code and PCR1
is for data such as ACPI and SMBIOS.
So let's switch over the DTB measurements to PCR1 which seems a better
fit.

Change type of ulong env_get_bootm_low() to phys_addr_t env_get_bootm_low().
The PPC/LS systems already treat env_get_bootm_low() result as phys_addr_t,
while the function itself still returns ulong. This is potentially dangerous
on 64bit systems, where ulong might not be large enough to hold the content
of "bootm_low" environment variable. Fix it by using phys_addr_t, similar to
what env_get_bootm_size() does, which returns phys_size_t .

Sometimes the kernel is built as an EFI application rather than a
binary. We still want to support compression for this case.
For arm64 the entry point is set later in the bootm_load_os() function,
since these images are typically relocated due to the 2MB-alignment
requirement of arm64 images. But since the EFI image is not in the same
format, we need to update the entry point earlier.
Set the entry point always, for kernel_noload to resolve this problem.
It should be harmless to do this always.

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)

Use the bootm_info struct to hold the information required by bootm.
Now that none of the functions called from do_bootm_states() needs an
argv[] list, change the arguments of do_bootm_states() as well. Take
care to use the same value for boot_progress even though it is a little
inconsistent.
For booti make sure it only uses argv[] and argc at the top of the
function, so we can eventually refactor to remove these parameters.
With bootm, some OSes need access to the arguments provided to the
command, so set these up in the bootm_info struct, for bootm only.

The problem is that the arm64 magic is checked before the image is
decompressed. However this is only part of it. The kernel_noload image
type doesn't work with compression, since the kernel is not loaded. So
this series deals with that by using an lmb-allocated buffer for the
uncompressed kernel.
Another issue is that the arm64 handling is done too early, before the
image is loaded. This series moves it to after loading, so that
compression can be handled.
A patch is included to show the kernel load-address, so it is easy to
see what is going on.
One annoying feature of arm64 is that the image is often copied to
another address. It might be possible for U-Boot to figure that out
earlier and decompress it to the right place, but perhaps not.
With all of this it should be possible to boot a compressed kernel on
any of the 990 arm64 boards supported by Linux, although I have only
tested two.

If the image is compressed, then the existing check fails, since the
