The section header address is a VMA whereas the address found in
the program header is a physical one. With this change it is
possible to load and start a vx7 intel generic based image.
$ readelf -l /tmp/vx7
Elf file type is EXEC (Executable file)
Entry point 0x408000
There are 2 program headers, starting at offset 52

Thanks for the patch. Did you verify booting a VxWorks 6.x kernel?
Last time I tested 'bootvx' was on Intel Galileo board with VxWorks 7.
I will find some time to test this patch.
