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

Posted by Jim Shu 2 years, 4 months ago

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

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
