Similar to bl31_warm_entrypoint, sp_min-based platforms may need
that for special resume handling.
Therefore move it from the private header to the sp_min platform header.

Rockchip re-uses the ti uart console driver and for aarch32 needs a
specific variant, so add it.
There are also aarch32 ti socs, so it may be useful for them as well
at some point.

When we get a sequence ID that does not match what we expect then the we
are looking at is not the one we are expecting and so we error out. We
can also assume this message is a stale message left in the queue, in
this case we can read in the next message and check again for our
message. Switch to doing that here. We only retry a set number of times
so we don't lock the system if our message is actually lost and will
never show up.

The sequence ID can be set with a message to identify it when it is
responded to in the response queue. We assign each message a number and
check for this same number to detect response mismatches.
Start this at 0 and increase it by one for each message sent, even ones
that do not request or wait for a response as one may still be delivered
in some cases and we want to detect this.

Support booting OP-TEE as BL32 boot stage and secure runtime
service.
OP-TEE executes in internal RAM and uses a secure DDR area to store
the pager pagestore. Memory mapping and TZC are configured accordingly
prior OP-TEE boot. OP-TEE image is expected in OP-TEE v2 format where
a header file describes the effective boot images. This change
post processes header file content to get OP-TEE load addresses
and set OP-TEE boot arguments.

The BL1 stage setup code for ARM platforms sets up the SP805 watchdog
controller as the secure watchdog. But not all ARM platforms use SP805
as the secure watchdog controller.
So introduce two new ARM platform code specific wrapper functions to
start and stop the secure watchdog. These functions then replace the
calls to SP805 driver in common BL1 setup code. All the ARM platforms
implement these wrapper functions by either calling into SP805 driver
or the SBSA watchdog driver.

On Cortex A9 an errata can cause the processor to violate the rules for
speculative fetches when the MMU is off but branch prediction has not
been disabled. The workaround for this is to execute an Invalidate
Entire Branch Prediction Array (BPIALL) followed by a DSB.

mention that a platform must have a platform_oid.h header file
in order to successfully build the cert_create tool when
USE_TBBR_DEFS is 0.

This file is used when building the cert_create tool without using
the 'standard' set of Arm OID values as defined in the TBBR
specification (see tbbr_oid.h). This configuration is enabled by
setting USE_TBBR_DEFS to 0 during build.
At the moment this will fail because the header file included by
this file was removed in commit bb41eb7a9d ("cert: move
platform_oid.h to include/tools_share for all platforms"). For
the SGM platform this means that there is no current use for
this file.
