The SMCCC, part 3 indicates that only the bottom
32-bits of a 32-bit SMC call are valid. The upper
bits must be zero. Lets enforce that so standard
service code can assume its been called that way.

Added support for HW computed CRC using Arm ACLE intrinsics.
These are built-in intrinsics available for ARMv8.1-A, and
onwards.
These intrinsics are enabled via '-march=armv8-a+crc' compile
switch for ARMv8-A (supports CRC instructions optionally).

HW CRC support is enabled unconditionally in BL2 for all Arm
platforms.

HW CRC calculation is verified offline to ensure a similar
result as its respective ZLib utility function.

HW CRC calculation support will be used in the upcoming
firmware update patches.

* changes:
  docs(prerequisites): add `--no-save` to `npm install`
  fix(hooks): downgrade `package-lock.json` version

To avoid the mistake fixed by the previous commit, ensure users install
the Node.js dependencies without polluting the lock file by passing
`--no-save` to the `npm install` line.

The NPM lock file was accidentally updated using a later version of
Node.js than required by the prerequisites. This upgraded the lock file
to the v2 format, which causes a warning on Node.js 14 (the
prerequisites version). This moves the lock file back to v1 by
installing the dependencies with Node.js 14.

An indirect dependency of Commitizen (`merge`) is currently failing the
NPM.js auditor due to vulnerability CVE-2020-28499. This commit moves
the minimum version of Commitizen to 4.2.4, which has resolved this
vulnerability.

In the comment in the ARM FPGA DT we promise a generous 100 MB initrd,
but actually describe only a size of 20 MB.

As initrds are the most common and easy userland option for the boards,
let's increase the maximum size to the advertised 100 MB, to avoid
unpacking errors when an initrd exceeds the current limit of 20 MB.

on i.MX8MP A1 silicon, the OCRAM space is extended to 512K + 64K,
currently, OCRAM @0x960000-0x980000 is reserved for BL31, it will
leave the last 64KB in non-continuous space. To provide a continuous
384KB + 64KB space for generic use, so move the BL31 space to
0x970000-0x990000 range.

To compare the "okay" string of a property, strncmp is used but with the
length given by fdt_getprop. This len value is reported as tainted by
Coverity [1]. We just can use strlen("okay") which is a known value
to compare the 2 strings.
