The comment suggests checking version numbers and
a checksum but there doesn't seem to be any usable
data for either of these.
For example, fip_toc_header_t doesn't contain any
version information and neither does fip_toc_entry_t.
As the function name "is_valid_header" suggests, this
function is not concerned with checksumming any of
the table of contents entries.

It is quite unlikely that this number will ever change and, if it
does need to change, we should have a good reason to do so. It
seems that this comment is now redundant.

The SCTLR.DSSBS bit is zero by default thus disabling speculative loads.
However, we also explicitly set it to zero for BL2 and TSP images when
each image initialises its context. This is done to ensure that the
image environment is initialised in a safe state, regardless of the
reset value of the bit.

There are some issues with synopsys MMC driver:
- CMD8 should not expect data (for SD)
- ACMD51 should expect data (Send SCR for SD)
- dw_prepare should not dictate size to be MMC_BLOCK_SIZE, block size is
now handled in the dw_prepare function
- after the CMD completes, when doing dw_read, we need to invalidate cache
and wait for the data transfer to complete
- Need to set FIFO threshold, otherwise DMA might never get the interrupt
to read or write

So far the DT node describing the AXP803 PMIC used in many Allwinner A64
boards had only one subnode, so our code just entering the first subnode
to find all regulators worked fine.
However recent DT updates in the Linux kernel add more subnodes *before*
that, so we need to make sure to explicitly enter the "regulators"
subnode to find the information we are after.
Improve some DT node parsing error handling on the way.

The BL handover interface stores the bootloader arguments in
registers r9-r12, so when the reset_handler stores the lr pointer
in r10 it clobers one of the arguments.
Adapt to use r8 and adapt the comment about registers allowed
to clober.
I've checked aarch32 reset_handlers and none seem to use higher
registers as far as I can tell.

In the current Pointer Authentication support added in
commit b86048c40c
PAuth gets enabled in BL31 cold boot entrypoint only,
(see bl31_entrypoint() in bl31\aarch64\bl31_entrypoint.S)
but not in bl31_warm_entrypoint().
This results in EnIA bit [31] in SCTLR_EL3 not being set
and pointer authentication disabled after CPU wake-up event.

Some bugs in MMC stack needs to be fixed:
- scr cannot be local as this will cause cache issue when invalidating
after the read DMA transfer is completed
- ACMD41 needs to send voltage information in initialization, otherwise the
command is a query, thus will not initialize the controller
- when checking device state, retry until the retries counter goes to zero
before failing
