The ti_sci driver in U-Boot has support for secure_msg as part of it's
do_xfer function. This let's U-boot send secure messages during boot up.
The protocol to send such secure messages is described as part of the
struct ti_sci_secure_msg_hdr. As part of this, there are 2 fields for
checksum and reserved that occupy the first 4 bytes of any secure
message. This is called as the secure_hdr.
As of now, the secure_hdr needs to be 0 init-ed before sending secure
messages. However the existing code was never putting the zero-inited vars
into the secure_buf, leading to possibility of the first 4 bytes of
secure_buf being possibly garbage.
Fix this by initialising the secure_hdr itself to the secure_buf
location, thus when we make secure_hdr members 0, it automatically ensures
the first 4 bytes of secure_buf are 0.

When setting up boot media to load the TIFS binary in legacy boot flow
(followed by J721E), get_timer() is called which calls dm_timer_init()
which then gets the tick-timer: mcu_timer0. mcu_timer0 uses k3_clks
(clock controller) and k3_pds (power controller) from the dmsc node that
forces probe of the ti_sci driver of TIFS that hasn't been loaded yet!
Running ti_sci_cmd_get_revision from the probe leads to panic since no
TIFS and board config binaries have been loaded yet. Resolve this by
moving ti_sci_cmd_get_revision to ti_sci_get_handle_from_sysfw as a
common point of invocation for both legacy and combined boot flows.
Before doing this, it is important to go through whether any sync points
exist where revision is needed before ti_sci_get_handle_from_sysfw is
invoked. Going through the code along with boot tests on both flows
ensures that there are none.

We can check if the message was acknowledged in the common

The inline hint is not needed here, the compiler will do the right thing
based on if we are compiling for speed or for code size. In this case the
inline causes this function to be placed inside each callsite which is
not the right thing to do for either speed nor size. There is no
performance benefit to this due to the larger function size reducing
cache locality, but there is a huge size penalty. Remove inline keyword.

On J721e and J7200, MCU R5 core (boot master) itself would run Device
Manager (DM) Firmware and interact with TI Foundational Security (TIFS)
firmware to enable DMA and such other Resource Management (RM) services.
So, during R5 SPL stage there is no such RM service available and ti_sci
driver will have to directly interact with TIFS using DM to DMSC
channels to request RM resources.
Therefore add DT binding and driver for the same. This driver will
handle Resource Management services at R5 SPL stage.

This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.
Coincidentally it also ensures that every declaration is on one line,

At present dm/device.h includes the linux-compatible features. This
requires including linux/compat.h which in turn includes a lot of headers.
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.
Move the compatibility features into a separate header file.

Any host while requesting for a device can request for its exclusive

responsibility to release the device before the software entity on
the host completes its execution. Else any other host's request for
the device will be nacked. So add a command that releases all the
exclusive devices that is acquired by the current host. This should

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.

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
for exclusive and shared device requests.

An earlier commit converted the TISCI receive timeouts to be specified
in ms rather than us however it failed to take this change into account
when passing the actual timeout to be used when invoking the mailbox
receive API. This leads to the actual timeout to be 1,000 times shorter
than expected and as a result certain TISCI operations would fail.

as expected by the respective API.
