docs: Update note about plat/arm in Porting Guide

drivers: partition: Add simple MBR partition entries support

plat: intel: Fix faulty DDR calibration value

hikey960: enable IOMCU DMAC

Platforms are not allowed to use any file inside include/plat/arm or
plat/arm to prevent dependencies between Arm platforms and non-Arm
platforms.

imx: warp7: Migrate to MULTI_CONSOLE_API

TI-SCI asynchronous power down sequencing

A DDR calibration value is missing write mask, causing ECC DDR calibration
to fail. This patch addresses the issue. ECC should also be scrubbed before
MMU initializes, thus the scrubbing is moved to ddr intialization phase.

This is to add simple MBR partition entry support. This will read all four
MBR partition into the partition list, and the partition type will be saved
in the list.name[0] entry.

Fix CPU headers' definitions

Sanitize SPD include paths

doc: Fix broken external links

Commit 09d40e0e

 ("Sanitise includes across codebase") modified the
include paths of the TSP includes but it didn't remove the include path
from the makefile or did the same for TLK. This patch does the remaining
work.

This commit migrates to MULTI_CONSOLE_API for IMX Warp7 board.
We also rename the functions in imx_uart driver to more specific one.

ATF should be the only host needing to control a processor that it has
started. ATF will need this control to stop the core later. Do not
relinquish control of a core after starting the core.

Now that we have non-blocking TI-SCI functions we can initiate the shutdown
sequence from the PSCI handler without needing the ti_sci_proc_shutdown
helper function, which is removed. This gives us the greater control and
flexibility that will be needed when cluster power down sequences are added.

Most TI-SCI functions request an ACK and wait until it is received. For
some power sequence tasks we cannot wait but instead queue messages
asynchronously. Three messages have been identified that will need to
be used in this way. Add non-waiting versions of these functions.

Currently almost all TI-SCI messages request and check for an ACK from
the system firmware. Move this into a common place to remove the same
from each function.

When a device is requested with TI-SCI its control can be made exclusive
to the requesting host. This was currently the default but is not what
is needed most of the time. Add _exclusive versions of the request
functions and remove the exclusive flag from the default version.

The raw get and set state functions for both devices and clocks
are only meant for use internal to the TI-SCI driver, the same
functionality is available from the other API that call into
these. Remove them from the external interface and make them
static scope to the driver.

There exists a third DMA controller on the hi3660
SoC called the IOMCU DMAC. This controller is used by
peripherals like SPI2 and UART3. Initialize channels 4-7
as non-secure, while 0-3 remain reserved and secure.

There are some incorrect casts and some missing casts in the headers.
This patch fixes the ones that were 64-bit or 32-bit wide wrongly and
adds casts where they were missing.

Note that none of the changes of the patch actually changes the values
of the definitions. This patch is just for correctness.

There are some values that should be 64-bit immediates but that resolve
to 0 because the type of the value is 32-bit wide. This patch casts the
expressions to 64-bit before the shift so that the definition has the
correct value.

The definitions are only used in assembly so far, so the code is not
actually affected by this bug. The assembler treats all values as 64-bit
values, so there are no overflows.

Make setjmp/longjmp compliant with the C standard and move them to libc

maintainers: Fix broken links to some Github accounts

Miscellaneous documentation fixes

Using Sphinx linkcheck on the TF-A docs revealed some broken
or permanently-redirected links. These have been updated where
possible.

Now that setjmp() and longjmp() are compliant with the standard they can

Instead of having a custom implementation of setjmp() and longjmp() it
is better to follow the C standard.

The comments in setjmp.h are no longer needed as there are no deviations
from the expected one, so they have been removed.

All SDEI code that relied on them has been fixed to use the new function
prototypes and structs.

The armclang compiler can warn if a variable is declared but
is never referenced. The '__attribute__((unused))' attribute
informs the compiler to expect an unused variable, and tells
it not to issue a warning.

This patch marks the 'xlat_clean_dcache_range' function as
"unused" to fix this armclang compiler warning.

This patch introduces explicit linker variables to mark the start and
end of the per-cpu bakery lock section to help bakery_lock_normal.c
calculate the size of the section. This patch removes the previously
used '__PERCPU_BAKERY_LOCK_SIZE__' linker variable to make the code
uniform across GNU linker and ARM linker.
