ed94fc2fd4 nand-part: Avoid Linux-only ioctl() on other platforms 
The nand-part.c code tries to re-read the partition tables
by issuing an ioctl(fd, BLKRRPART, NULL). This isn't available
on non-Linux platforms, e.g. Mac OS X.

Add preprocessor conditionals to prevent this from breaking
the build.

5d0ee5037b nand-part: create one nand-part program to handle both A10 and A20 
Build one nand-part program to handle both A10 and A20 mbr header formats.
Changed -f option to take an "a10" or "a20" argument to specify which mbr
format to force.

c20d395d59 set MBR_MAGIC to "softw411" and MBR_VERSION to 0x200 in nand-part-a20.h 
A20 boot1 checks the MBR magic string but not the version, but let's
check it anyway (can always force now with the -f option if the version
isn't 0x200 on the system)

653ae97b0c display partition numbers starting at "1" instead of "0"; corresponds to 
command usage and partition numbering in linux nand driver

606c0688d3 added backwards compatibility with older version of nand-part: if the starting 
offset of partition 1 isn't specified, switch to old argument syntax that retains
partition 1 values

dd94a2f117 build both A10 and A20 nand-part executables 
allow setting of partition 1 size/offset
if -f option is used, force writing of MBR header, even if CRC or
header magic/version are incorrect (for recovery only)
