The zipl internal loader adds a variable BOOT_IMAGE= to the commandline
so that it is visible in the operating system which menu entry has been
chosen.
This entry was overwritten by the stage3 parameter page.
Fix by re-arranging the internal memory layout and putting the command
line extra param, which contains the BOOT_IMAGE entry, at 0xe000.
This location is available because less than one page is used for the
stack.
