From e0e784a456c4d64e5e88ce578371fe6c538db559 Mon Sep 17 00:00:00 2001 From: "Ronald G. Minnich" Date: Wed, 26 Nov 2014 19:25:47 +0000 Subject: Add UCB RISCV support for architecture, soc, and emulation mainboard.. Works in the RISCV version of QEMU. Note that the lzmadecode is so unclean that it needs a lot of work. A cleanup is in progress. We decided in Prague to do this as one thing, because it forms a nice case study of the bare minimum you need to add to get a new architecture going in qemu.
