Void pointers have been used to access linker symbols, by declaring an
extern pointer, then taking the address of it. This limits symbols
values to aligned pointer values. To remove this restriction an
IMPORT_SYM macro has been introduced, which declares it as a char
pointer and casts it to the required type.

Don't make build results depend on dependency files

Change PLATFORM_ROOT to TF_PLATFORM_ROOT

Rename 'smcc' to 'smccc'

tegra: Use SPDX license identifier

When the source code says 'SMCC' it is talking about the SMC Calling
Convention. The correct acronym is SMCCC. This affects a few definitions
and file names.

Some files have been renamed (smcc.h, smcc_helpers.h and smcc_macros.S)
but the old files have been kept for compatibility, they include the
new ones with an ERROR_DEPRECATED guard.

x3 will be assigned by the folloing instructions.
So the first instruction is not needed any more.

old method:
  (ClusterId * FVP_MAX_CPUS_PER_CLUSTER)
+ (CPUId * FVP_MAX_PE_PER_CPU)
+ ThreadId

it should be
  (ClusterId * FVP_MAX_CPUS_PER_CLUSTER) * FVP_MAX_PE_PER_CPU
+ (CPUId * FVP_MAX_PE_PER_CPU)
+ ThreadId

which can be simplified as:
(ClusterId * FVP_MAX_CPUS_PER_CLUSTER + CPUId) * FVP_MAX_PE_PER_CPU + ThreadId

FVP AArch32: Fix flash access in BL32 for mem_protect

The FVP platform port for SP_MIN (BL32) didn't map the flash memory
in BL32 for stroring the mem_protect enable state information leading
to synchronous exception. The patch fixes it by adding the region to
the BL32 mmap tables.

Implement support for v1.2 of firmware interfaces spec (ARM DEN 0070A)

When querying `SMCCC_ARCH_WORKAROUND_1` through `SMCCC_ARCH_FEATURES`,
return either:
  * -1 to indicate the PE on which `SMCCC_ARCH_FEATURES` is called
    requires firmware mitigation for CVE-2017-5715 but the mitigation
    is not compiled in.
  * 0 to indicate that firmware mitigation is required, or
  * 1 to indicate that no firmware mitigation is required.

This patch complies with v1.2 of the firmware interfaces
specification (ARM DEN 0070A).

Juno: Fixes for firmware update

hikey: migrate to BL2_EL3

Previously, Juno used to depend on the SSC_GPRETN register to inform
about the reset syndrome. This method was removed when SCP migrated
to the SDS framework. But even the SDS framework doesn't report the
reset syndrome correctly and hence Juno failed to enter Firmware
update mode if BL2 authentication failed.

In addition to that, the error code populated in V2M_SYS_NVFLAGS register
does not seem to be retained any more on Juno across resets. This could
be down to the motherboard firmware not doing the necessary to preserve
the value.

Hence this patch modifies the Juno platform to use the same mechanism to
trigger firmware update as FVP which is to corrupt the FIP TOC on
authentication failure. The implementation in `fvp_err.c` is made common
for ARM platforms and is moved to the new `arm_err.c` file in
plat/arm/common folder. The BL1 and BL2 mmap table entries for Juno
are modified to allow write to the Flash memory address.

Fix build with clang on hikey

This issue was detected when testing FWU on Juno. The Timer
`timer_ops` was not being initialized before being used by
the SDS driver on Juno. This patch adds the call to
`generic_delay_timer_init()` during bl2u_early_platform_setup().
This is done generically for all ARM platforms because the
cost involved is minimal.
