[Qemu-devel] [PATCH 3/3] Basic implementation of Sharp Zaurus SL-5500 collie PDA |
Date: |
Thu, 24 Mar 2011 13:22:59 +0300 |
Add very basic implementation of collie PDA emulation. The system lacks
LoCoMo and graphics/sound emulation. Linux kernel boots up to mounting
rootfs (theoretically it can be provided in pflash images).
