[Qemu-devel] [PATCH v2] use an unsigned long for the max_sz parameter in load_image_targphys

[Mark Langsdorf]

Allow load_image_targphys to load files on systems with more than 2G of
emulated memory by changing the max_sz parameter from an int to an
unsigned long.

The other loaders in hw/loader.h did not look they had a similar issue.

Changes from v1
        changed max_sz from unsigned long to target_phys_addr_t
        returned size to an int to match get_image_size
