1. All Makefiles that use ARM_APCS_FLAGS add -marm unconditionally and
bsd.own.mk also adds it for gcc only (so we end up with 2 -marm for gcc).
Just add -marm unconditionally in bsd.own.mk in ARM_APCS_FLAGS and remove
it from everywhere else.
2. gcc-8 now warns about thumb internetwork in APCS mode. This does not make
sense because the documentation says that this flag does not make a
difference in apcs mode, but might produce larger code in non-APCS mode.

Fix-up boot32 to work on A7000+

Logically the previous code should have worked but didn't. It appeared to
fail when reading the relocation table from physical memory.

To work-around this issue we now compact the relocation table (it shrinks
from ~800 entries to ~15 on a 2.5MB kernel) The compacted table is small
enough to copy into the page of memory we use to do the relocations. The
relocation code can now find the table, and carry out the relocations.

To help with debugging the screen border will change colour:
Red: Running without the MMU turned on (IE 1-1 physical mapping)
Note that the border will stay red a while as we're copying the
kernel over at this point.
Green: We've finished copying the kernel over (unless the code breaks
this will be rarely seen)
Blue: We're running on the bootstrap L1 table, and just about to call
the kernel.

Other tweaks include:
* copy the kernel 32bits at a time, rather than 8 bits at a time.
* assert that the relocations are 32bit aligned (so the above works)
* flush the cache and write buffers before turning off the MMU.

Tested by myself on an A7000+. Tested by skrll@ on Risc-PC and A7000.

Fix support for kinetic in the bootloader.

With these changes the kinetic dram blocks are correctly identified and

Note that I've a pending kernel change to understand the kinetic blocks

Zero out the whole of the structure, not just the first 4 bytes. IE use
sizeof(*bconfig) not sizeof(bconfig)

Now a small kernel will boot up on my RISC-PC, an install kernel won't

Don't rely on first_mapped_PODRAM_page_index being zero on systems without
PODRAM, especially since it's initialised to -1. Instead, use
(podram_blocks != 0) to decide when to use it. This still doesn't make
my Risc PC boot, but it generates a believable relocation table now.

When looking for somewhere to put the relocation table, reset the counter of
contingous pages to zero when we find a non-contiguous one. This way, we'll
actually find a contiguous block of the correct size (assuming there is one).
The updated version still boots my NC correctly, and fails slightly more
pleasantly on mr Risc PC.

Use normal array subscripting syntax in place of addition and dereferencing.
No binary code change.

Ah yes, _that's_ why we don't use field widths in printf() here: libsa's
printf() doesn't support them. Revert to using print0() while I ponder the
matter.

Use slightly more advanced printf() formats to replace the horrid print0()
function.

Fix miscelanious small errors that arose from having non Mb aligned memory

Small fixes that showed up during boot-testing of a Pace DSL4000 running

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

In the case there is just one SIMM and one memory bank from the SIMM things
got wrong when no VRAM was there.

Placing the video DRAM in front of the kernel is OK when its 1Mb since the
kernel wants to be on a Mb boundary. Placing the video DRAM in the last
SIMM bank at the front is also OK unless there is just one SIMM and just one
bank; then it got in the way again!

Solution is to put the DRAM at the end of the SIMM instead of the beginning!
This however can result in the non 16 kb alignment of the top of physical
RAM where the temporary L1 page tables are situated. If its not 16 kb aligned
then move the L1 page table address down and down until it is 16 kb aligned.
This memory will be reused later on anyway.

What to do when we really support changing screensizes... see it as a max?
or use a different sceme alltogether? It might not even be a bootloader
problem then allthough its memory is not showing up in the DRAM/VRAM
block counts wich needs to be fixed one day.

Since we dont support switching screenmodes (yet) we might as well claim
just enough for the screenmemory to be in instead of the maximum of 1Mb.
Small machines like my 8Mb NC get a 700 kb back and thats really noticeable.

If we don't have VRAM then at least account the screensize correctly :) it goes
pretty wierd if it is set wrongly.

If we nick memory from the DRAM for video then please account it correctly!

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.

Silly error: xos_cli() should call XOS_CLI, not OS_CLI.

Pass the argument to OSModule_Free in the correct register. This stops
NBFS leaking memory.

Add some definitions necessary for the latest NBFS, plus a couple of
functions that my boot32 hacks are likely to require.

Add code to support access to RISC OS disk devices from libsa. This is
sufficient to allow a small wrapper program to access files on the NetBSD
partition of a shared disk. NetBSD-only disks don't work (FileCore objects
to the lack of a boot block), and there's no code to actually use this
facility yet.

Don't reset devices if booting an Iyonix. It's fine for acorn32 devices
because we know how to configure all of the hardware, but as we don't know
how to configure the Iyonix graphics card we must rely on RISC OS to do
it for us.

While we're here, space separate the kernel arguments. It's a bit hard

Retire varargs.h support. Move machine/stdarg.h logic into MI
