This change allows platforms to provide more than one linker script to

In its place, additional linker scripts may be added to the

Adds a pre-commit git hook to keep track of copyright year.
Checks staged files for Arm copyright header and suggests a change if
the year is outdated. Works with both single-year format and

The tos_fw_config is currently loaded into memory by BL2 and
consumed by SPMD (part of BL31) and BL32 firmwares. This does
not work in RME-enabled systems as BL31 uses the root PAS memory
and does not trust secure PAS memory.
A first attempt was made to map the TOS_FW_CONFIG region as root PAS,
and then to remap to secure PAS after SPMD consumption, but this was
not suitable for RME systems where memory encryption is enabled.
This can be solved by copying the TOS FW config (SPMC manifest) from
the Root PAS region to the Secure PAS region so that BL32 can consume
it.

some of them having issues.
Export a generic implementation of that function in fdt_wrappers.h, as
a "static inline" function to not increase code size.
Also replace the existing implementation in Arm's fconf code, which had
a tiny bug in needlessly using the property length:
"status = [6f 6b 61 79 20];" would pass the check, where it should not.
The proper solution is also simpler: status must be a string, and
strings must be NUL-terminated in a DT. strcmp() would terminate on the
first NUL in *either* of the two strings it compares, so it would never
walk beyond the property boundary in the DTB.
