Tracepoints would be preferable to more DPRINTF macros for
new devices, ideally.

PERIPH_CLK2_SEL is a 2-bit field, right? Since there's
nothing that prevents the guest from writing 0b11 to it,
we need a case 3: here. (The guest should never be able
to trigger a QEMU assertion failure.)

You don't need a 'break' here, as execution never returns
from g_assert_not_reached(). The comment I think also
can be dropped -- it just tells you what you can already
determine from the g_assert_not_reached().

It looks like the index is forced to be in range by the size
of this MemoryRegion. An assertion here will help to convince
static analysis tools that this really can't overflow the array.
(Similarly in the write fn below.)

Please don't define ad-hoc extract macros. Either just use
extract32() directly, or use the macros that include/hw/registerfields.h
provides.

thanks
