core: arm: mm: fix core_mmu_xlat_table_alloc() for nexus

core_mmu_xlat_table_alloc() allocates new translation tables from
boot_mem until during early boot and after the MMU has been enabled with
nex_phys_mem_core_alloc() or phys_mem_core_alloc(). However, the logic
selecting which function to call doesn't take the default partition into
account. The default partition has only a nexus physical memory pool so
nex_phys_mem_core_alloc() must be called if that partition is active. So
fix the problem with an extra check for default_partition.

core: arm: ffa: add framework for Logical SPs

Add a framework to register Logical Secure Partitions in parallel with
OP-TEE at S-EL1. This is akin to Pseudo TAs, it provides an ABI but it's
part of the OP-TEE binary. A critical difference is that it's only
available for FF-A and can only use the non-threaded environment, that
is, no mutexes or RPC.

The logical OP-TEE core partition is registered in the framework. The
SPMC is also registered in the framework, but with a nil UUID so it's
not returned by FFA_PARTITION_INFO_GET.

edk2's StandaloneMm will be applied with FF-A v1.2.
while applying, StandaloneMm doesn't create anymore PHIT hob by itself

To make StandaloneMm runs properly, create Hob information and

Also, apply FF-A management protocol to change it [2] to
get/set memory permission instead of using DIRECT_REQ_MSG.

Also, implements some FF-A ABIs to communication StandaloneMm properly.

According to Platform Initialization (PI) Specification [1] and

That's why StandaloneMm in Arm wouldn't produce Hob by itself [3] but
other software stack should pass boot information via PHIT Hob.

Add the macros for Sv57 address translation mode. Add CFG_RISCV_MMU_MODE
into riscv.mk and set it as 39 by default to enable Sv39 virtual address
translation scheme.

Currently, TA virtual memory occupies 1GB space, and TAs page table
should be an entry inside a level 2 (VPN[2]) page table, which is
decided by user_va_idx variable. For Sv39 translation scheme, it starts
from VPN[2], so nothing to do. For Sv48 translation scheme, we need to
allocate entry 0 of level 3 (VPN[3]) page table, and let it point to the
level 2 page table used by TA. For Sv57 translation scheme, we need to
further allocate entry 0 of level 4 (VPN[4]) page table, and let it
point to the level 3 page table.

scheme is not Sv39.

For RV32, there is only two-level VPN. The user VA range would be inside
