Hi. Apologies for not getting to this patch earlier -- I've been
busy with a bunch of other work and the QEMU 2.6 release.

In general this patch looks good, but unfortunately it doesn't compile:

hw/display/blizzard.c: In function ‘s1d13745_init’:
hw/display/blizzard.c:948:5: error: expected ‘;’ before ‘s’
     s->line_fn_tab[0] = blizzard_draw_fn_32;
     ^
In file included from hw/display/blizzard.c:929:0:

This is because you're missing a semicolon here.

It's important to at least compile and preferably also test
any patch you send to the list. (Occasionally it's not possible
if the code in question requires an obscure host OS or
library combination or something, in which case you should
note in the patch remarks below the "---" line that you weren't
able to compile test.)

In this case (and since it took me so long to get back to this
patch) I've just fixed up this error and applied the result to
target-arm.next.

There are a couple of nice further cleanups we can do on top
of this to remove blizzard_template.h altogether; I'll post
those patches in a moment.

thanks
