Michael Nolan [Mon, 4 May 2020 17:07:07 +0000 (13:07 -0400)]
Flatten the output of RecordObject.ports()
If a record contains records, calling ports on it will give a result
that cannot be passed to the nmigen simulation backend. This flattens
it, so that ports() will just return signals

sigh, rename of signals needed for nmigen compatibility with FIFOInterface
Luke Kenneth Casson Leighton [Wed, 18 Mar 2020 11:27:47 +0000 (11:27 +0000)]
realised that the enable lines will act just as well as port-enable lines
from MultiPriorityPicker, so make the binary-indices optional but
the enable-outputs mandatory
Luke Kenneth Casson Leighton [Tue, 17 Mar 2020 22:21:02 +0000 (22:21 +0000)]
realised that the MultiPriorityPicker only needs a 1D array of inputs
not a 2D array of input bits. input is chain-cascaded from previous
PriorityPicker after masking

create MultiPriorityPicker which can mutually-exclusively select M outputs from
Mx N-way inputs
to be used for example to ensure that M "things" seeking access to M
"other things" do not conflict: that only one "thing" at a time gets access
to the
other "things"
