[Qemu-devel] [PATCH 0/3] target-xtensa: fix loading uImage kernels on MMUv2 cores

[Max Filippov <jcmvbkbc@gmail.com>]

Hi,

this series fixes loading uImage kernels on MMUv2 xtensa cores.

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.

I add two new functions: load_uboot_image_header that loads uImage header
and load_uimage_at that loads uImage at the specified address, and use them
to query uImage load address and load uImage at the correctly translated
address.

Max Filippov (3):
  hw/core/loader: implement load_uboot_image_header
  hw/core/loader: implement load_uimage_at
  target-xtensa: treat uImage load address as virtual
