1 sibling, 0 replies; 3+ messages in thread
From: Beniamino Galvani @ 2013-12-15 17:17 UTC (permalink / raw)
To: barebox
The OpenCores 10/100 Mbps ethernet MAC is often available on
OpenRISC-based SoCs and is supported by the OpenRISC architectural
simulator (or1ksim) as well.
The patch enables the driver on the 'generic' openrisc board.
