[PATCH v3 00/12] riscv: Add support for P8700 platform on Boston board

[Uros Stajic]

This patch series adds platform support for the P8700 processor
running on the Boston board.

P8700-F is a high-performance RV64GC SoC that supports hardware
multithreading and optional multi-cluster configurations.

----
Changes in v3:
- 01/12 - Split original patch into CPU/Board parts
- 02/12 - New patch: extracted board-specific logic from original 01/12
- 01/12 - Relocated object rule for p8700 into p8700-specific Makefile
- 01/12 - Explained .word usage for mcache instruction and replaced it
          with symbolic macro
- 01/12 - Replaced inline assembly lw instruction with readl()
- 01/12 - Removed p8700 code from start.S, moved to harts_early_init()
- 02/12 - Fixed operand spacing in assembly
- 02/12 - Replaced hardcoded address with properly macros
- 02/12 - Switched from riscv,isa to riscv,isa-extensions
- 02/12 - Sorted DT properties properly

Changes in v2:
- 03/11 - Remove redundant pcie_xilinx_probe() and update commit
	  message accordingly.
