hexdumpmem
==========

[About]:
hexdumpmem is hexdump-like tool to dump memory and write memory. When 
developing a system on a SoC, I usually need to dump or write 
memory-map registers of the SoC for debugging. I write this program
to do it on my developing Android phone. 

[Usage]:
1. Dump a memory region:
        % hexdumpmem -a 0x1000
        Memory region 0x00001000 ~ 0x0000116f
        addr              0        4        8        C
