Change type of ulong env_get_bootm_low() to phys_addr_t env_get_bootm_low(). The PPC/LS systems already treat env_get_bootm_low() result as phys_addr_t, while the function itself still returns ulong. This is potentially dangerous on 64bit systems, where ulong might not be large enough to hold the content of "bootm_low" environment variable. Fix it by using phys_addr_t, similar to what env_get_bootm_size() does, which returns phys_size_t .
