- move the helper programs txlt and aout2bb to the topmost directory
- build the few files from libsa in the topmost directory
* while doing this, hunted down mysterious code expansion: It seems
that ld aligns code segments differently when linking .o's directly
than when using an archive consisting of the same files. Abuse this
effect to make the bootblock even smaller. The floppy boot block
"fdboot" is now small enough to build; add it back to the Makefile.
* while being here, remove a file which was committed by mistake.
along with toolchain enhancements.
aout2bb transforms a.out files with reloc information into bootblock format
files with a compressed relocation info.
bbstart.s relocates the bootblock using this compressed info, before jumping
to C code.
txlt changes some more of the absolute references to pc-relative ones (we know
we have a single code + data address space).
If you ever try to change this: don't even dare to change the compiler options;
they were found in weeks of trial and error as the ones producing the smallest
(not necessarily fastests) code.
installboot is just a script around dd, for now.
Some ideas by Michael Hitch, Leo Weppelman and Jason Thorpe; bugs added
by myself.

in a more elegant way, but it works as is, and we need it now.
- Add a README and Makefile for the above. Note that this directory should
NOT be added to ../Makefile's SUBDIRS.
loading into fastmem. This removes the requirement that the kernel fit
into chipmem.
Add a -Z flag to force loading into chip memory.
Add a -s option for compatibility with my bootblock loader.
Move the test exit to just before starting the kernel; this lets the
test mode actually load the kernel and do the version checks.

Now use amiga HW for soft interrupts, non-contig options (2 or many chunks),
interrupt handler lists, 4066 ethernet, 1291 scsi, option to defer level 6
interrupts to level 4 (deal with icky built-in serial port)

- scsi drivers for a2091 and gvp-II controllers in a2k
- working ethernet driver for a2065/ameristar lance-controllers

up on an A3000. There are still (very) few changes required outside the
arch/amiga tree, so you can't recompile the kernel yet. Support for
third party SCSI controllers for the A2000 is on its way. The kernel is
fully functional (except for a missing ethernet-driver ...). This
tree is based on my version #390.
