qemu_v8: tfa: set ENABLE_FEAT_HCX=2 #697

Closed jforissier closed 8 months ago

Build Trusted Firmware-A with ENABLE_FEAT_HCX=2. This is needed to use SPMC_AT_EL=2 with kernel v6.5 or later (any version that has commit "KVM: arm64: initialize HCRX_EL2" [1]). The symptom is a PANIC message in the platform secure console (out/bin/serial1.log):

I/TC: Primary CPU switching to normal world boot PANIC at PC : 0x000000000e0a13c4

Note that this PR should fix all the CI failures we are seeing in optee_os pull requests (the make check (QEMUv8, Hafnium) job).
