This PR lets the LVBS platform (i.e., HEKI/HVCI) use physical pointer
abstraction to access VTL0 memory. This is equivalent to the OP-TEE
shim's normal-world memory access such that it is not only safer than
the legacy VTL0 memory copy functions (i.e.,
`copy_(slice_)(from|to)_vtl0_phys`) but also supporting virtually
contiguous access of non-contiguous physical page frames.

This PR lets the LVBS platform (i.e., HEKI/HVCI) use physical pointer
abstraction to access VTL0 memory. This is equivalent to the OP-TEE
shim's normal-world memory access such that it is not only safer than
the legacy VTL0 memory copy functions (i.e.,
`copy_(slice_)(from|to)_vtl0_phys`) but also supporting virtually
contiguous access of non-contiguous physical page frames.

No description provided.

This PR lets the LVBS platform (i.e., HEKI/HVCI) use physical pointer
abstraction to access VTL0 memory. This is equivalent to the OP-TEE
shim's normal-world memory access such that it is not only safer than
the legacy VTL0 memory copy functions (i.e.,
`copy_(slice_)(from|to)_vtl0_phys`) but also supporting virtually
contiguous access of non-contiguous physical page frames.

No description provided.

This PR lets the LVBS platform (i.e., HEKI/HVCI) use physical pointer
abstraction to access VTL0 memory. This is equivalent to the OP-TEE
shim's normal-world memory access such that it is not only safer than
the legacy VTL0 memory copy functions (i.e.,
`copy_(slice_)(from|to)_vtl0_phys`) but also supporting virtually
contiguous access of non-contiguous physical page frames.
