  hw/riscv: Extend the kernel loading support (2019-06-27 02:47:06 -0700)

----------------------------------------------------------------
RISC-V Patches for the 4.1 Soft Freeze, Part 2 v3

This pull request contains a handful of patches that I'd like to target
for the 4.1 soft freeze.  There are a handful of new features:

* Support for the 1.11.0, the latest privileged specification.
* Support for reading and writing the PRCI registers.
* Better control over the ISA of the target machine.
* Support for the cpu-topology device tree node.

Additionally, there are a handful of bug fixes including:

* Load reservations are now broken by both store conditional and by
  scheduling, which fixes issues with parallel applications.
* Various fixes to the PMP implementation.
* Fixes to the 32-bit linux-user syscall ABI.
* Various fixes for instruction decodeing.
* A fix to the PCI device tree "bus-range" property.

This boots 32-bit and 64-bit OpenEmbedded.

Changes since v2 [riscv-for-master-4.1-sf1-v2]:

* Dropped OpenSBI.

Changes since v1 [riscv-for-master-4.1-sf1]:

* Contains a fix to the sifive_u OpenSBI integration.
