[PATCH 0/4] esp-pci: fixes for Linux and MS-DOS

[Mark Cave-Ayland]

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.
