[PATCH 0/4] Parallel message send using SBI MPXY

[Anup Patel <anup.patel@oss.qualcomm.com>]

This series primarily extends mailbox framework and SBI MPXY mailbox
driver to allow sending messages in-parallel from multiple CPUs. It
also serves as perparatory series for the upcoming RISC-V ACPI EINJ
support and RISC-V TEE support.

These patches can also be found in the riscv_mpxy_imp_v1 branch at:
https://github.com/avpatel/linux.git

Amirreza Zarrabi (2):
  RISC-V: Factor-out per-hart MPXY shared-memory acquisition
  mailbox: add direct synchronous send support

Anup Patel (2):
  RISC-V: Move common MPXY helper routines to arch/riscv
  mailbox: riscv-sbi-mpxy: Move to send_data_sync() for sending messages
