This is excellent news; I looked what could be done about updating the
ecos orc platform based on the OpenRISC fork about a year ago after the
excellent OpenRISC talk at FOSDEM, but was not able to find out who the
real authors were so that the copyright re-assignment could be done.

I am not a maintainer, but since these are two different architectures,
my inkling would be toward renaming the current architecture to
something like 'hal/openrisk1k' so that later on you can add
'hal/openrisk2k'.
