[Qemu-devel] [PATCH v2 2/2] hw/xtensa/xtfpga: treat uImage load address as virtual

[Max Filippov <jcmvbkbc@gmail.com>]

U-boot for xtensa always treats uImage load address as virtual address.
This is important when booting uImage on xtensa core with MMUv2, because
MMUv2 has fixed non-identity virtual-to-physical mapping after reset.

Always do virtual-to-physical translation of uImage load address and
load uImage at the translated address. This fixes booting uImage kernels
on dc232b and other MMUv2 cores.

- use translate_phys_addr with the new load_uimage interface.
