This series contains fixes for the esp-pci device (am53c974 or dc390) for a
few issues spotted whilst testing the previous ESP series.
Patches 1-3 are fixes for issues found by Helge/Guenter whilst testing the
hppa C3700 machine with the amd53c974/dc390 devices under Linux, whilst patch
4 fixes an issue that was exposed by testing MS-DOS and Windows drivers.
With this series applied on top of the reworked ESP device, it is possible to
boot Linux under qemu-system-hppa without any errors and also boot and install
Win98SE from a DC390 PCI SCSI controller (no IDE!) using an MS-DOS boot floppy.

Mark Cave-Ayland (4):
esp-pci.c: use correct address register for PCI DMA transfers
esp-pci.c: generate PCI interrupt from separate ESP and PCI sources
esp-pci.c: synchronise setting of DMA_STAT_DONE with ESP completion
interrupt
esp-pci.c: set DMA_STAT_BCMBLT when BLAST command issued
Is it worth to pick up for stable? Especially the first one.
It's interesting this bug is here for a very long time.. :)
Good question! I did my comprehensive boot tests with this series on top of the core
ESP series so I can't say that I've tested this series on its own. Then again other
than the DMA_STAT_DONE patch which is a timing change, the rest of the patches are
fixing specific edge cases which were already broken so I would be surprised if
anything broke.
ATB,
Mark.
