[PATCH v2 0/2] Align SiFive PDMA behavior to real hardware

[Jim Shu]

HiFive Unmatched PDMA supports high/low 32-bit access of 64-bit
register, but QEMU emulation supports low part access now. Enhance QEMU
emulation to support high 32-bit access. 

Also, permit 4/8-byte valid access in PDMA as we have verified 32/64-bit
accesses of PDMA registers are supported.

Changelog:

v2:
  * Fix high 32-bit write access of 64-bit RO registers
  * Fix commit log

Jim Shu (2):
  hw/dma: sifive_pdma: support high 32-bit access of 64-bit register
  hw/dma: sifive_pdma: permit 4/8-byte access size of PDMA registers
