[Qemu-devel] [PATCH arm-devs v3 8/9] arm/xilinx_zynq: Implement CBAR initialisation |
Date: |
Mon, 2 Dec 2013 23:03:31 -0800 |
Fix the CBAR initialisation by using the newly defined static property.
Zynq will now correctly init the CBAR to the SCU base address.
Needed to boot Linux on the xilinx_zynq machine model.
Signed-off-by: Peter Crosthwaite <address@hidden>

changed since v1:
use error report rather than fprintf(stderr
rename SCU_BASE_ADDR to MPCORE_PERIPHBASE
