Guess I understand the code now - so here is a working version - though
it may be considered slightly hackish

Title:
hw/esp.c does not properly deal with TEST_UNIT_READY in NetBSD/sparc
Status in QEMU:
New
Bug description:
The NetBSD ncr53c9x.c driver does a TEST_UNIT_READY command with
SELATN but dma disabled sometimes (early during bus enumeration). This
is fine, as the command will not produce nor consume any data, and
works on real hardware.
However, the qemu emulation does not allow this (for reasons I don't
understand).
The change below fixes the problem.
