Zhou, Wu b394777908 HV: Add implements of 32bit and 64bit elf loader ... This is a simply implement for the 32bit and 64bit elf loader. The loading function first reads the image header, and finds the program entries that are marked as PT_LOAD, then loads segments from elf file to guest ram. After that, it finds the bss section in the elf section entries, and clear the ram area it points to. Limitations: 1. The e_type of the elf image must be ET_EXEC(executable). Relocatable or dynamic code is not supported. 2. The loader only copies program segments that has a p_type of PT_LOAD(loadable segment). Other segments are ignored. 3. The loader doesn’t support Sections that are relocatable (sh_type is SHT_REL or SHT_RELA) 4. The 64bit elf’s entry address must below 4G. 5. The elf is assumed to be able to put segments to valid guest memory.
