lib: Add hexdump
Often during debugging session it's very interesting to see what data we were dealing with. For example what we write or read to/from memory or peripherals. This change introduces functions that allow to dump binary data with one simple function invocation like: ------------------->8---------------- print_hex_dump_bytes("", DUMP_PREFIX_OFFSET, buf, len); ------------------->8---------------- which gives us the following: ------------------->8---------------- 00000000: f2 b7 c9 88 62 61 75 64 72 61 74 65 3d 31 31 35 ....baudrate=115 00000010: 32 30 30 00 62 6f 6f 74 61 72 67 73 3d 63 6f 6e 200.bootargs=con 00000020: 73 6f 6c 65 3d 74 74 79 53 33 2c 31 31 35 32 30 sole=ttyS3,11520 00000030: 30 6e 38 00 62 6f 6f 74 64 65 6c 61 79 3d 33 00 0n8.bootdelay=3. 00000040: 62 6f 6f 74 66 69 6c 65 3d 75 49 6d 61 67 65 00 bootfile=uImage. 00000050: 66 64 74 63 6f 6e 74 72 6f 6c 61 64 64 72 3d 39 fdtcontroladdr=9 00000060: 66 66 62 31 62 61 30 00 6c 6f 61 64 61 64 64 72 ffb1ba0.loadaddr 00000070: 3d 30 78 38 32 30 30 30 30 30 30 00 73 74 64 65 =0x82000000.stde 00000080: 72 72 3d 73 65 72 69 61 6c 30 40 65 30 30 32 32 rr=serial0@e0022 00000090: 30 30 30 00 73 74 64 69 6e 3d 73 65 72 69 61 6c 000.stdin=serial 000000a0: 30 40 65 30 30 32 32 30 30 30 00 73 74 64 6f 75 0@e0022000.stdou 000000b0: 74 3d 73 65 72 69 61 6c 30 40 65 30 30 32 32 30 t=serial0@e00220 000000c0: 30 30 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00.............. ... ------------------->8---------------- Source of hexdump.c was copied from Linux kernel v4.7-rc2.
