[Skyeye-developer] Patch for load address of elf file

[kang shuo]

Problem description:
 we can not directly execute linux elf image that run on platform with
MMU on SkyEye and  we need to modify linux source file to fit its
virtual address.. For the entry point of these elf image is always set
to a virtual address such as 0xc000xxxxx. In fact probabely they need
to be loaded to 0xa000xxxx.

Solvement:
Now I add an option "l" in skyeye. We  can  load elf file to another
address not the entry point of this elf file by this option. Thus some
kernel of elf format can run on SkyEye correctly without any
modification of linux source.

Now we can run pxa testcase by the following command :
binary/skyeye -e vmlinux -l 0xa0000000,0x0fffffff

The patch is in the attachment. If no any issues on it, I will commit it soon.

- Thanks
