Stop attempts to boot a kernel that is bigger than the first DRAM block.

At the moment too much stuff assumes that the kernel is contiguous in
physical memory.

While this doesn't make an INSTALL kernel work for me it at least now
indicates what the fault is, and I can swap the memory sticks round.

branches: 1.11.58; 1.11.62; 1.11.68; 1.11.70;
Add support to boot32 for passing a real vsync frequency to NetBSD.
Unfortunately, RISC OS doesn't seem to provide a sensible way to ask what
frame rate it's using so we resort to measuring it ourselves.

branches: 1.10.4; 1.10.8;
merge ktrace-lwp.

branches: 1.9.12;
Adjust the reserved heap space based on memory size. This avoids running out
of heap on machines with large amounts of memory. Tested on 33MB RISC OS 4
and 128MB RISC OS 5 machines. Updated version to 3.40.

Add qsort to libsa (taken from sys/dev/vinum/vinumqsort.c) and use instead of
bubblesort in acorn32 bootloader. Reduces time to sort memory on A710 equipped
RiscPC from over twenty seconds to effectively instantaneous.
Update boot version to 3.30

branches: 1.7.2; 1.7.4;
Cleanup DRAM video memory allocation. This needed to be done anyway and it
also ought to solve bootproblems with the A7000(+) family.

As an extra benefit, the surplus memory of the screen is returned to the
memorypool.

Fixup serious loading problems (together with the former commit of start.S)
major code cleanup esp. types used. Also cleanup up a major BUG that for
some odd reason worked :-/ makes me puzzled. It signifies that there might
be copies around in physical space of the DRAM ??? and thus its function
was motherboard dependent? It must have been old cruft from before the
cleanup of the relocation engine.

Fix miscelanious small errors that arose from having non Mb aligned memory
for the videoscreen.

Small fixes that showed up during boot-testing of a Pace DSL4000 running
the RISC OS-STB 4.0.0 version of RISC OS.

We have version 3.02 now : just a small fix for bootkernel name guessing.

Oeps... forgot the versions file

branches: 1.1.2;
Initial commit of the 3rd generation of bootloaders for the Acorn32
platform. It features far better support for newer architectures and is
fully rewritten in C and compile-able under NetBSD.

Since it shares code with `boot26' for Acorn26 merging the common parts is
likely to be next on the list.
