firmware: ti_sci: Add processor shutdown API method
Add and expose a new processor shutdown API that wraps the two TISCI
messages involved in initiating a core shutdown. The API will first
queue a message to have the DMSC wait for a certain processor boot
status to happen followed by a message to trigger the actual shutdown-
with both messages being sent without waiting or requesting for a
response. Note that the processor shutdown API call will need to be
followed up by user software placing the respective core into either
WFE or WFI mode.

firmware: ti_sci: Allow for device shared and exclusive requests
Sysfw provides an option for requesting exclusive access for a
device using the flags MSG_FLAG_DEVICE_EXCLUSIVE. If this flag is
not used, the device is meant to be shared across hosts. Once a device
is requested from a host with this flag set, any request to this
device from a different host will be nacked by sysfw. Current tisci
driver enables this flag for every device requests. But this may not
be true for all the devices. So provide a separate commands in driver

binman: Convert Image to a subclass of Entry
When support for sections (and thus hierarchical images) was added to
binman, the decision was made to create a new Section class which could
be used by both Image and an Entry_section class. The decision between
using inheritance and composition was tricky to make, but in the end it
was decided that Image was different enough from Entry that it made sense
to put the implementation of sections in an entirely separate class. It
also has the advantage that core Image code does have to rely on an entry
class in the etype directory.
This work was mostly completed in commit:
8f1da50ccc "binman: Refactor much of the image code into 'section'
As a result of this, the Section class has its own version of things like
offset and size and these must be kept in sync with the parent
Entry_section class in some cases.
In the last year it has become apparent that the cost of keeping things in
sync is larger than expected, since more and more code wants to access
these properties.
An alternative approach, previously considered and rejected, now seems
better.
Adjust Image to be a subclass of Entry_section. Move the code from Section
(in bsection.py) to Entry_section and delete Section. Update all tests
accordingly.
This requires substantial changes to Image. Overall the changes reduce
code size by about 240 lines. While much of that is just boilerplate from
Section, there are quite a few functions in Entry_section which now do not
need to be overiden from Entry. This suggests the change is beneficial
even without further functionality being added.
A side benefit is that the properties of sections are now consistent with
other entries. This fixes a problem in testListCmd() where some properties
are missing for sections.
Unfortunately this is a very large commit since it is not feasible to do
the migration piecemeal. Given the substantial tests available and the

remoteproc: Fix potential build issues with SPL remoteproc
The rproc uclass driver can either be built with SPL_REMOTEPROC
or REMOTEPROC, but the function prototypes in remoteproc.h are
defined only when CONFIG_REMOTEPROC is defined. This can cause
build issues in SPL if CONFIG_REMOTEPROC is not selected.
Fix this by replacing the existing precompiler macro usage with
CONFIG_IS_ENABLED.

doc: Cope with Sphinx logging deprecations
Recent versions of sphinx will emit messages like:
doc/sphinx/kerneldoc.py:103:
RemovedInSphinx20Warning: app.warning() is now deprecated.
Use sphinx.util.logging instead.
Switch to sphinx.util.logging to make this unsightly message go away.
Alas, that interface was only added in version 1.6, so we have to add a
version check to keep things working with older sphinxes.

'ab_select' command is used to decide which slot should be used for
booting up. A/B metadata resides in 'misc' partition.
To activate the A/B boot process, the following config options must be
set:
CONFIG_ANDROID_AB=y
CONFIG_CMD_AB_SELECT=y
For successful A/B boot, the corresponding A/B infrastructure must be
involved on Android side [1] (including mounting system as root), and
disk must be partitioned accordingly.
When A/B boot is enabled, there are some known limitations currently
exist (not related to A/B patches, need to be implemented later):
1. The 'Verified Boot' sequence is not supported
2. dev path to system partition (system_a or system_b) is passed via
'bootargs' as 'root=' argument like 'root=/dev/mmcblk1p12', but
further we'll need to rework it with respect to dm-verity
requirements [2]
In case when A/B partitions are not present in system (and A/B boot is
enabled), boot up process will be terminated and next message will be
shown:
