H A Dsp_min-stm32mp1.mkcd0786c73e536a1d2507d77ce49e2ae2b8ee71a1 Tue Mar 14 10:15:05 UTC 2023 Stephan Gerhold <stephan@gerhold.net> fix(bl32): always include arm_arch_svc in SP_MIN

The PSCI_FEATURES call implementation in TF-A always indicates support
for SMCCC_VERSION, but only BL31 ensures that the corresponding Arm
Architecture Service (arm_arch_svc) is really included in the build.
For SP_MIN only stm32mp1 currently includes it in the platform-specific
make file.

This means that it is easily possible to build configurations that
violate the PSCI/SMCCC specification. On Linux this leads to incorrect
detection of the SMC Calling Convention when using SP_MIN:

[ 0.000000] psci: SMC Calling Convention v65535.65535

Fix this by always including the Arm Architecture Service in SP_MIN
builds. This allows Linux to detect the convention correctly:

[ 0.000000] psci: SMC Calling Convention v1.4
