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
parsing them in the kernel when they're all run together.

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.

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.

chris | Fix support for kinetic in the bootloader.
With these changes the kinetic dram blocks are correctly identified and
passed into the kernel.
Note that I've a pending kernel change to understand the kinetic blocks
and do something useful with them.
|
| 1.31 |
| 21-Jan-2008 |
chris | 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
though, it hangs at the switch from RISC-OS to NetBSD.

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.

bjh21 | branches: 1.27.4;
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.
|
| 1.26 |
| 25-Mar-2006 |
bjh21 | 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.
|
| 1.25 |
| 23-Mar-2006 |
bjh21 | Use normal array subscripting syntax in place of addition and dereferencing.
No binary code change.
|
| 1.24 |
| 23-Mar-2006 |
bjh21 | 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.
|
| 1.23 |

function.

RiscPC from over twenty seconds to effectively instantaneous.

meaningless.

reinoud | 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.
|

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

reinoud | Small fixes that showed up during boot-testing of a Pace DSL4000 running
the RISC OS-STB 4.0.0 version of RISC OS.
|
| 1.7 |
| 06-Jan-2003 |
reinoud | We have version 3.02 now : just a small fix for bootkernel name guessing.
|
| 1.6 |
| 30-Dec-2002 |
reinoud | 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.
|
| 1.5 |
| 30-Dec-2002 |
reinoud | 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.
|
| 1.4 |
| 30-Dec-2002 |
reinoud | If we don't have VRAM then at least account the screensize correctly :) it goes
pretty wierd if it is set wrongly.
|
| 1.3 |

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

The unique machine ID is used in some networking stuff to generate a
unique-ish number, so better add it again!
|

| 28-Dec-2002 |
reinoud | 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.
