2. Dev setup via variable
set fpga [dev]

4. Dev and address setup via variables

Before this patch only cases 1 and 3 are working but the part of code
was trying to support also cases 2 and 4.
This patch is adding support for cases 2 and 4 to have all of

tools: mkimage: Ensure munmap unmaps the same length that was mapped

The set_header call in kwbimage.c adds a checksum to the end of the
image in addition to setting up the header. It 'helpfully' updates the
st_size to match the fact that the file is now longer. However, mkimage
uses this length in the munmap call. This can lead to unmapping an extra
page, of perhaps required data. When this happens, a SEGV can occur.

To prevent this from happening, the munmap call now uses the same length
that was passed to mmap. This could also have been fixed by not changing
the length in kwbimage.c, however changing it in the main file means
that other plugins will also not fall for the same trap.
