◆ image_elf32_read_headers()

static int image_elf32_read_headers ( struct image * image )

static

some ELF linkers produce binaries with all the program header p_paddr fields zero (there can be however one loadable segment that has valid physical address 0x0). If we have such a binary with more than one PT_LOAD header, then use p_vaddr instead of p_paddr (ARM ELF standard demands p_paddr = 0 anyway, and BFD library uses this approach to workaround zero-initialized p_paddrs when obtaining lma - look at elf.c of BDF)
