2024-02-11hw/pci-host/astro: Implement Hard Fail and Soft Fail modeHelge Deller
The Astro/Elroy chip can work in either Hard-Fail or Soft-Fail mode. Hard fail means the system bus will send an HPMC (=crash) to the processor, soft fail means the system bus will ignore timeouts of MMIO-reads or MMIO-writes and return -1ULL. The HF mode is controlled by a bit in the status register and is usually programmed by the OS. Return the corresponing values based on the current value of that bit.
