Cortex A77 erratum 1508412 is a Cat B Errata present in r0p0 and r1p0.
The workaround is a write sequence to several implementation defined
registers based on A77 revision.

This errata is explained in this SDEN:

According to [1] and in context of FF-A v1.0 a secure partition must
have either one EC (migratable UP) or a number of ECs equal to the
number of PEs (pinned MP). Adjust the SPMC manifest such that the
number of ECs is equal to the number of PEs.

Implemented a parser which populates the properties of
the CoT descriptors as per the binding document [1].
'COT_DESC_IN_DTB' build option is disabled by default and can
be enabled in future for all Arm platforms by making necessary
changes in the memory map.
Currently, this parser is tested only for FVP platform.

Currently the feature test for the SPE extension requires the feature
bits in the ID_AA64DFR0 register to read exactly 0b0001.
However the architecture guarantees that any values greater than 0
indicate the presence of a feature, which is what we are after in
our spe_supported() function.

Change the comparison to include all values greater than 0.

This fixes SPE support in non-secure world on implementations which
include the Scalable Vector Extension (SVE), for instance on Zeus cores.

Although support for building fiptool on a Windows host was present,
the binary was not built when the top level makefile was invoked.

This patch makes the necessary changes to the to support building of
fiptool on a Windows host PC from the main makefile.

Windows does not have a standard getopt implementation. To address
this an equivalent implementation has been provided in win_posix.c
However, the implementation has an issue with option processing as
described below.

Long option names may be abbreviated if the abbreviation is unique
or an exact match for some defined option.
Since some options can be substring of other options e.g. "scp-fw"
option is a substring of "scp-fwu-cfg", we need to identify if an
option is abbreviated and also check for uniqueness. Otherwise if
a user passes --scp-fw as an option, the "scp-fwu-cfg" option may
get selected, resulting in an incorrectly packaged FIP.

This issue has been be fixed by:
  - First searching for an exact match.
  - If exact match was not found search for a abbreviated match.
By doing this an incorrect option selection can be avoided.

Neoverse N1 erratum 1868343 is a Cat B erratum, present in older
revisions of the Neoverse N1 processor core.  The workaround is to
set a bit in the CPUACTLR_EL1 system register, which delays instruction
fetch after branch misprediction. This workaround will have a small
impact on performance.

According to the documentation [1], KEY_SIZE defaults to 2048 when RSA
algorithm is chosen, so set this value on the make's defaults file.
