This function was needed at the time where we didn't have the
compiler_rt lib. An AArch32-specific variant was provided to handle
the 64-bit shift operation in 32-bit. This is no longer needed.

Imported from the LLVM compiler_rt library on master branch as of
30 Oct 2018 (SVN revision: r345645).
This is to get the __aeabi_llsr() builtin, which is required by a
subsequent patch that uses a logical right shift operator in AArch32.

Version 1.4.7 introduces a big performance hit to functions that access
the FDT. Downgrade the library to version 1.4.6-9, before the changes
that introduce the problem. Version 1.4.6 isn't used because one of the
libfdt files (fdt_overlay.c) is missing the license header. This
problem is also fixed in 1.4.6-9.
This version corresponds to commit <aadd0b65c987> checks: centralize
printing of property names in failure messages.

plat/arm files should only be used by Arm platforms. If other platforms
use them, they create dependencies that can introduce problems when
updating Arm platforms.
This patch copies the needed code from Arm platforms so that poplar can
be independent from them.

This patch enabled PIE for FVP when RESET_TO_BL31=1. The references
to BL31_BASE are replaced by BL31_START as being a symbol exported by
the linker, will create a dynamic relocation entry in .rela.dyn and
hence will be fixed up by dynamic linker at runtime. Also, we disable
RECLAIM_INIT_CODE when PIE is enabled as the init section overlay
creates some static relocations which cannot be handled by the
dynamic linker currently.

This patch introduces Position Independant Executable(PIE) support
in TF-A. As a initial prototype, only BL31 can support PIE. A trivial
dynamic linker is implemented which supports fixing up Global Offset
Table(GOT) and Dynamic relocations(.rela.dyn). The fixup_gdt_reloc()
helper function implements this linker and this needs to be called
early in the boot sequence prior to invoking C functions. The GOT is
placed in the RO section of BL31 binary for improved security and the
BL31 linker script is modified to export the appropriate symbols
required for the dynamic linker.
The C compiler always generates PC relative addresses to linker symbols
and hence referencing symbols exporting constants are a problem when
relocating the binary. Hence the reference to the
`__PERCPU_TIMESTAMP_SIZE__` symbol in PMF is removed and is now calculated
at runtime based on start and end addresses.

Previously the errata reporting was optional for CPU operation
files and this was achieved by making use of weak reference to
resolve to 0 if the symbol is not defined. This is error prone
when adding new CPU operation files and weak references are
problematic when fixing up dynamic relocations. Hence this patch
removes the weak reference and makes it mandatory for the CPU
operation files to define the errata reporting function.

This patch fixes up the AArch64 assembly code to use
adrp/adr instructions instead of ldr instruction for
reference to symbols. This allows these assembly
sequences to be Position Independant. Note that the
the reference to sizes have been replaced with
calculation of size at runtime. This is because size
is a constant value and does not depend on execution
address and using PC relative instructions for loading
them makes them relative to execution address. Also
we cannot use `ldr` instruction to load size as it
generates a dynamic relocation entry which must *not*
be fixed up and it is difficult for a dynamic loader
to differentiate which entries need to be skipped.
