Commit 270f8710f9 ("crc32: Add crc32 implementation using
__builtin_aarch64_crc32b") enabled the usage of ARMv8 CRC instructions
by default, for all arm64 builds. And indeed all Arm Ltd. v8 Cortex-A
cores support the instructions, and they are mandatory starting with
architecture revision v8.1, so realistically every known hardware
implementation should support them.
The Arm Fastmodel however defaults to the bare minimum ARMv8 feature set
by default, which means v8.0 without the CRC instructions, so U-Boot
hangs very early at the moment, without any output (the boot-wrapper or
TF-A printing the last visible lines).
Support for those instructions can be enabled on the model command line
by either:
-C cluster0.cpu0.enable_crc32=1 (for each core)
or by using a higher architecture revision by default:
-C cluster0.has_arm_v8-1=1 (for each cluster)
Of course any arch revision higher than v8.1 would work as well.
But for the sake of a smooth out-of-the-box experience, let's just
disable the usage of those instructions in the defconfig, to avoid
random hangs without any clues.
