Hi John,

it is currently emulating mbvanilla to the minimimal extent to run to
the prompt - its strange the the console works with no UART
interrupts! I would not have believed that!
but it does. Maybe because the emulated uartlite TX is never busy so
all data is sent out instantly always and TX buffer never filled.

it is planned to have the simulator to parse
.MHS file and load peripheral support modules using module handler
mapping file.

at the moment I am stuck with systemACE support, I enabled it in
kernel, then I had to enable DOS partition as well after that the
system is initialized, but after first read sector commands there
comes IRQ what is handled correctly - sysace irq reset, re-enabled
INTC IAR reset, then there is one read to sysace status register, and
thats where booting hangs!

so I am not sure where the problem is, as I have not had uClinux with
sysace working so far. :(
