2023-06-07soc/amd/common/block/cpu/noncar: add get_usable_physical_address_bits()Felix Held
In case the secure memory encryption is enabled, some of the upper usable address bits of the host can't be used any more. Bits 11..6 in CPUID_EBX_MEM_ENCRYPT indicate how many of the address bits are taken away from the usable address bits in the case the secure memory encryption is enabled.
