Peter Maydell 3add3f7edc RISC-V: QEMU 2.13 Privileged ISA emulation updates
Several code cleanups, minor specification conformance changes,
 fixes to make ROM read-only and add device-tree size checks.
 
 * Honour privileged ISA v1.10 counter enable CSRs.
 * Implements WARL behavior for CSRs that don't support writes
   * Past behavior of raising traps was non-conformant
     with the RISC-V Privileged ISA Specification v1.10.
 * Allow S-mode access to sstatus.MXR when priv ISA >= v1.10
 * Sets mtval/stval to zero on exceptions without addresses
   * Past behavior of leaving the last value was non-conformant
     with the RISC-V Privileged ISA Specition v1.10. mtval/stval
     must be set on all exceptions; to zero if not supported.
 * Make ROMs read-only and implement device-tree size checks
   * Uses memory_region_init_rom and rom_add_blob_fixed_as
 * Adds hexidecimal instruction bytes to disassembly output.
 * Fixes missing break statement for rv128 disassembly.
 * Several code cleanups
   * Replacing hard-coded constants with enums
   * Dead-code elimination
 
 This is an incremental pull that contains 20 reviewed changes out
 of 38 changes currently queued in the qemu-2.13-for-upstream branch.
