Improve MULTI_CONSOLE_API deprecation warnings

For platforms that have not migrated to MULTI_CONSOLE_API == 1, there
are a lot of confusing deprecated declaration warnings relating to
use of console_init() and console_uninit(). Some of these relate to use
by the generic code, not the platform code. These functions are not really
deprecated but *removed* when MULTI_CONSOLE_API == 1.

This patch consolidates these warnings into a single preprocessor warning.
The __deprecated attribute is removed from the console_init() and
console_uninit() declarations.

For preprocessor warnings like this to not cause fatal build errors,
this patch adds -Wno-error=cpp to the build flags when
ERROR_DEPRECATED == 0.
This option (and -Wno-error=deprecated-declarations) is now added to
CPPFLAGS instead of TF_CFLAGS to ensure the build flags are used in the
assembler as well as the compiler.

This patch also disentangles the MULTI_CONSOLE_API and ERROR_DEPRECATED
build flags by defaulting MULTI_CONSOLE_API to 0 instead of
ERROR_DEPRECATED. This allows platforms that have not migrated to
MULTI_CONSOLE_API to use ERROR_DEPRECATED == 1 to emit a more meaningful
build error.

Finally, this patch bans use of MULTI_CONSOLE_API == 1 and AARCH32, since
the AArch32 console implementation does not support
MULTI_CONSOLE_API == 1.

Invalidate TLB entries during warm boot

During the warm boot sequence:

1. The MMU is enabled with the data cache disabled. The MMU table walker
   is set up to access the translation tables as in cacheable memory,
   but its accesses are non-cacheable because SCTLR_EL3.C controls them

2. The interconnect is set up and the CPU enters coherency with the
   rest of the system.
3. The data cache is enabled.

If the support for dynamic translation tables is enabled and another CPU
makes changes to a region, the changes may only be present in the data
cache, not in RAM. The CPU that is booting isn't in coherency with the
rest of the system, so the table walker of that CPU isn't either. This
means that it may read old entries from RAM and it may have invalid TLB
entries corresponding to the dynamic mappings.

This is not a problem for the boot code because the mapping is 1:1 and
the regions are static. However, the code that runs after the boot
sequence may need to access the dynamically mapped regions.

This patch invalidates all TLBs during warm boot when the dynamic
translation tables support is enabled to prevent this problem.

EHF: Introduce preempted return code parameter to ehf_allow_ns_preemption()

When a Yielding SMC is preempted, it's possible that Non-secure world is
resumed afterwards. In this case, Non-secure execution would find itself
in a state where the SMC has returned. However, the dispatcher might not
get an opportunity to populate the corrected return code for having
been preempted, and therefore the caller of the Yielding SMC cannot
reliably determine whether the SMC had successfully completed or had
been preempted.

To solve this, this patch introduces a new parameter to the
ehf_allow_ns_preemption() API. An SPD, through this parameter, would
provide the expected error code when a Yielding SMC is preempted. EHF
can then populate the specified value in x0 of the Non-secure context so
that the caller of the Yielding SMC correctly identifies the SMC return
as a preemption.

Documentation updates to follow.

When the MMU is enabled and the translation tables are mapped, data

specified in the translation tables themselves. However, the MMU
performs table walks with the attributes specified in TCR_ELx. They are
completely independent, so special care has to be taken to make sure

This has to be done manually because it is not practical to have a test
in the code. Such a test would need to know the virtual memory region
that contains the translation tables and check that for all of the
tables the attributes match the ones in TCR_ELx. As the tables may not

drivers:ufs: fix hynix ufs bug with quirk on hi36xx SoC

Hynix ufs has deviations on hi36xx platform which will result
in ufs bursts transfer failures at a very low probability.

To fix the problem, the Hynix device must set the register
VS_DebugSaveConfigTime to 0x10, which will set time reference
for SaveConfigTime is 250 ns. The time reference for SaveConfigTime
is 40 ns by default.

Redefine SMC_UNK as -1 instead of 0xFFFFFFFF

    The Unknown SMC Function Identifier is a sign-extended value of
    (-1) that is returned in R0, W0 or X0 register.

The value wasn't sign-extended because it was defined as a 32-bit
unsigned value (0xFFFFFFFF).

SMC_PREEMPT has been redefined as -2 for the same reason.

NOTE: This might be a compatibility break for some AArch64 platforms
that don't follow the previous version of the SMCCC (ARM DEN0028A)
correctly. That document specifies that only the bottom 32 bits of the
returned value must be checked. If a platform relies on the top 32 bits
of the result being 0 (so that SMC_UNK is 0x00000000FFFFFFFF), it will
have to fix its code to comply with the SMCCC.
