There are two communication scheme that have been enabled to communicate
with Secure Proxy in TI.
a) A full fledged prioritized communication scheme, which involves upto
5 threads from the perspective of the host software
b) A much simpler "lite" version which is just a two thread scheme
involving just a transmit and receive thread scheme.
The (a) system is specifically useful when the SoC is massive
involving multiple processor systems and where the potential for
priority inversion is clearly a system usecase killer. However, this
comes with the baggage of significant die area for larger number of
instances of secure proxy, ring accelerator and backing memories
for queued messages. Example SoCs using this scheme would be:
AM654[1], J721E[2], J7200[3] etc.
The (b) scheme(aka the lite scheme) is introduced on smaller SoCs
where memory and area concerns are paramount. The tradeoff of
priority loss is acceptable given the reduced number of processors
communicating with the central system controller. This brings about
a very significant area and memory usage savings while the loss of
communication priority has no demonstrable impact. Example SoC using
this scheme would be: AM642[4]
While we can detect using JTAG ID and conceptually handle things
dynamically, adding such a scheme involves a lot of unused data (cost
of ATF memory footprint), pointer lookups (performance cost) and still
due to follow on patches, does'nt negate the need for a different
build configuration. However, (a) and (b) family of SoCs share the
same scheme and addresses etc, this helps minimize our churn quite a
bit
Instead of introducing a complex data structure lookup scheme, lets
keep things simple by first introducing the pieces necessary for an
alternate communication scheme, then introduce a second platform
representing the "lite" family of K3 processors.
NOTE: This is only possible since ATF uses just two (secure) threads
for actual communication with the central system controller. This is
sufficient for the function that ATF uses.
The (a) scheme and the (b) scheme also varies w.r.t the base addresses
used, even though the memory window assigned for them have remained
consistent. We introduce the delta as part of this change as well.
This is expected to remain consistent as a standard in TI SoCs.

commit 65f7b81728 ("ti: k3: common: Use coherent memory for shared data")
introduced WARMBOOT_ENABLE_DCACHE_EARLY and USE_COHERENT_MEM to handle
multiple clusters across L3 cache systems. This is represented by
"generic" board in k3 platform.
On "lite" platforms, however, system level coherency is lacking since
we don't have a global monitor or an L3 cache controller. Though, at
a cluster level, ARM CPU level coherency is very much possible since
the max number of clusters permitted in lite platform configuration is
"1".
However, we need to be able to disable USE_COHERENT_MEM for the lite
configuration due to the lack of system level coherency.
See docs/getting_started/build-options.rst for further information.

Sec proxy data buffer is 60 bytes with the last of the registers
indicating transmission completion. This however poses a bit
of a challenge.
The backing memory for sec_proxy is regular memory, and all sec proxy
does is to trigger a burst of all 60 bytes of data over to the target
thread backing ring accelerator. It doesn't do a memory scrub when
it moves data out in the burst. When we transmit multiple messages,
remnants of previous message is also transmitted which results in
some random data being set in TISCI fields of messages that have been
expanded forward.
The entire concept of backward compatibility hinges on the fact that
the unused message fields remain 0x0 allowing for 0x0 value to be
specially considered when backward compatibility of message extension
is done.
So, instead of just writing the completion register, we continue
to fill the message buffer up with 0x0 (note: for partial message
involving completion, we already do this).
This allows us to scale and introduce ABI changes back into TF-A only
as needed.

ARM's generic timer[1] picks up it's graycode from GTC. However, the
frequency of the GTC is supposed to be programmed in CNTFID0[2]
register.
In K3, architecture, GTC provides a central time to many parts of the
SoC including graycode to the generic timer in the ARMv8 subsystem.
However, due to the central nature and the need to enable the counter
early in the boot process, the R5 based bootloader enables GTC and
programs it's frequency based on central needs of the system. This
may not be a constant 200MHz based on the system. The bootloader is
supposed to program the FID0 register with the correct frequency it
has sourced for GTC from the central system controller, and TF-A is
supposed to use that as the frequency for it's local timer.
A mismatch in programmed frequency and what we program for generic
timer will, as we can imagine, all kind of weird mayhem.
So, check the CNTFID0 register, if it is 0, warn and use the default
frequency to continue the boot process.
While at it, we can also check CNTCR register to provide some basic
diagnostics to make sure that we don't have OS folks scratch their
heads. Even though this is used during cpu online operations, the cost
of this additional check is minimal enough for us not to use #ifdeffery
with DEBUG flags.

Current implementation doesn't support change of div1 value if clk
has 2 divisor because div1 clk is the parent of the div2 clk and div2
clk does not have SET_RATE_PARENT flag.
This causes div1 value to be fixed and only value of div2 will be
adjusted according to required clock rate.
Example:
Consider a case of nand_ref clock which has 2 divisor and 1 mux.
The frequency of mux clock is 1500MHz and default value of div1 and
div2 is 15 and 1 respectively. So the final clock will be of 100MHz.
When driver requests 80MHz for nand_ref clock, clock framework will
adjust the div2 value to 1 (setting div2 value 2 results final clock
to 50MHz which is more inaccurate compare to 100Mhz) which results
final clock to 100MHz.
Ideally the value of div1 and div2 should be updated to 19 and 1
respectively so that final clock goes to around 78MHz.
This patch fixes above problem by allowing change in div1 value.
