[Qemu-devel] [RFC PATCH 12/12] ppc: Add aCube Sam460ex board |
|
Date: |
Sun, 13 Aug 2017 19:04:38 +0200 |
Add emulation of aCube Sam460ex board based on AMCC 460EX embedded SoC.
This is not a full implementation yet with a lot of components still
missing but enough to start a Linux kernel and the U-Boot firmware.
