commit 62367091b42a97eb70cef062d5bbbf85ede6abc0 Author: Stefan Reinauer reinauer@chromium.org Date: Mon Jan 7 13:21:22 2013 -0800
qemu-x86: Implement more features
This patch switches the Qemu target to use (pseudo) Cache As RAM and enables some ACPI code. This allows to use the CBMEM console and timestamp code with coreboot in Qemu. Right now, the ACPI code is commented out because leaving it in breaks IDE.
