SDEI: Make dispatches synchronous
SDEI event dispatches currently only sets up the Non-secure context
before returning to the caller. The actual dispatch only happens upon
exiting EL3 next time.
However, for various error handling scenarios, it's beneficial to have
the dispatch happen synchronously. I.e. when receiving SDEI interrupt,
or for a successful sdei_dispatch_event() call, the event handler is
executed; and upon the event completion, dispatcher execution resumes
after the point of dispatch. The jump primitives introduced in the
earlier patch facilitates this feature.
With this patch:
- SDEI interrupts and calls to sdei_dispatch_event prepares the NS
context for event dispatch, then sets a jump point, and immediately
exits EL3. This results in the client handler executing in
Non-secure.
- When the SDEI client completes the dispatched event, the SDEI
dispatcher does a longjmp to the jump pointer created earlier. For
the caller of the sdei_dispatch_event() in particular, this would
appear as if call returned successfully.
The dynamic workaround for CVE_2018_3639 is slightly shifted around as
part of related minor refactoring. It doesn't affect the workaround
functionality.
Documentation updated.
NOTE: This breaks the semantics of the explicit dispatch API, and any
exiting usages should be carefully reviewed.

BL31: Introduce jump primitives
This patch introduces setjmp() and ongjmp() primitives to enable
standard setjmp/longjmp style execution. Both APIs parameters take a
pointer to struct jmpbuf type, which hosts CPU registers saved/restored

As per the standard usage:
- setjmp() return 0 when a jump is setup; and a non-zero value when
returning from jump.
- The caller of setjmp() must not return, or otherwise update stack
pointer since.

SDEI: Determine client EL from NS context's SCR_EL3
Currently, the dispatcher reads from SCR_EL3 register directly to
determine the EL of SDEI client. This is with the assumption that
SCR_EL3 is not modified throughout. However, with RAS work flows, it's
possible that SCR_EL3 register contains values corresponding to Secure
world, and therefore EL determination can go wrong. To mitigate this,
always read the register from the saved Non-secure context.

ARM Platforms: Update CNTFRQ register in CNTCTLBase frame
Currently TF-A doesn't initialise CNTFRQ register in CNTCTLBase
frame of the system timer. ARM ARM states that "The instance of
the register in the CNTCTLBase frame must be programmed with this
value as part of system initialization."
The psci_arch_setup() updates the CNTFRQ system register but
according to the ARM ARM, this instance of the register is
independent of the memory mapped instance. This is only an issue
for Normal world software which relies on the memory mapped
instance rather than the system register one.
This patch resolves the issue for ARM platforms.
The patch also solves a related issue on Juno, wherein
CNTBaseN.CNTFRQ can be written and does not reflect the value of
the register in CNTCTLBase frame. Hence this patch additionally
updates CNTFRQ register in the Non Secure frame of the CNTBaseN.

plat/arm: Migrate AArch64 port to the multi console driver
The old API is deprecated and will eventually be removed.
Arm platforms now use the multi console driver for boot and runtime
consoles. However, the crash console uses the direct console API because
it doesn't need any memory access to work. This makes it more robust
during crashes.
The AArch32 port of the Trusted Firmware doesn't support this new API
yet, so it is only enabled in AArch64 builds. Because of this, the
common code must maintain compatibility with both systems. SP_MIN
doesn't have to be updated because it's only used in AArch32 builds.
The TSP is only used in AArch64, so it only needs to support the new
API without keeping support for the old one.
Special care must be taken because of PSCI_SYSTEM_SUSPEND. In Juno, this
causes the UARTs to reset (except for the one used by the TSP). This
means that they must be unregistered when suspending and re-registered
when resuming. This wasn't a problem with the old driver because it just
restarted the UART, and there were no problems associated with
registering and unregistering consoles.
The size reserved for BL2 has been increased.

Panic in BL1 when TB_FW_CONFIG is invalid
In Arm platforms, when using dynamic configuration, the necessary
parameters are made available as a DTB. The DTB is loaded by BL1 and,
later on, is parsed by BL1, BL2 or even both, depending on when
information from the DTB is needed.
When the DTB is going to be parsed, it must be validated first, to
ensure that it is properly structured. If an invalid DTB is detected
then:
- BL1 prints a diagnostic but allows execution to continue,
- BL2 prints a diagnostic and panics.
Now the behaviour of BL1 is changed so for it also to panic. Thus, the
behaviour of BL1 and BL2 is now similar.
Keep in mind that if BL1 only loads the DTB but it doesn't need to
read/write it, then it doesn't validate it. The validation is done only
when the DTB is actually going to be accessed.

allwinner: Introduce basic platform support
This platform supports Allwinner's SoCs with ARMv8 cores. So far they
all sport a single cluster of Cortex-A53 cores.
"sunxi" is the original code name used for this platform, and since it
appears in the Linux kernel and in U-Boot as well, we use it here as a
short file name prefix and for identifiers.
This port includes BL31 support only. U-Boot's SPL takes the role of the
primary loader, also doing the DRAM initialization. It then loads the
rest of the firmware, namely ATF and U-Boot (BL33), then hands execution
over to ATF.
This commit includes the basic platform code shared across all SoCs.
There is no platform.mk yet.

SPM: Treat SP xlat tables the same as others
The translation tables allocated for the Secure Partition do not need
to be treated as a special case. They can be put amongst the other
tables mapping BL31's general purpose memory. They will be mapped with
the same attributes as them, which is fine.
The explicit alignment constraint in BL31's linker script to pad the
last page of memory allocated to the Secure Partition's translation
tables is useless too, as page tables are per se pages, thus their
end address is naturally aligned on a page-boundary.
In fact, this patch does not change the existing behaviour. Since
patch
22282bb68a31 ("SPM: Move all SP-related info to SP context
struct"), the secure_partition.c file has been renamed into sp_xlat.c
but the linker script has not been properly updated. As a result, the
SP translation tables are not specifically put at the start of the
xlat_table linker section, the __SP_IMAGE_XLAT_TABLES_START__/_END__
symbols have the same value, the size of the resulting mmap_region
covering these xlat tables is 0 and so it is ignored.
