Added the documentation section of arch/arm32 to not let it dissapear.
Can't say for sure ig the interrupts/majors+minors files are still valid though.

# $NetBSD: bootloader,v 1.1 2001/10/18 00:05:00 reinoud Exp $
|
||||
|
||||
|
||||
The current bootloader (since 2001) is written in BASIC and is RISC OS
|
||||
version independent; it even runs on NC's.
|
||||
|
||||
In contrast to the old bootloader, the (new) bootloader is relocating the
|
||||
kernel itself at 0xf0000000. This address is fixed to support OFW
|
||||
machines which feature this start address.
|
||||
|
||||
The development of a 2nd stage bootloader is a possible extension.

Notes on interrupts.
|
||||
|
||||
Ok since interrupts can be chained the return value from an interrupt
|
||||
handler is important.
|
||||
|
||||
The following return values are defined :
|
||||
|
||||
-1 - interrupt may have been for us but not sure so pass it on
|
||||
0 - interrupt no serviced (not ours)
|
||||
interrupt serviced but pass on down the chain
|
||||
1 - interrupt serviced do not pass on down the chain
|
||||
|
||||
The important bit is whether the interrupt should be passed on down
|
||||
the chain of attached interrupt handlers.
|
||||
|
||||
For some interrupts and drivers where only a single device is
|
||||
ever expected, the interrupt should be claimed if it has been serviced.
|
||||
Passing it on down the chain may result in the stray interrupt handler
|
||||
being called.
|
||||
There are however some interrupt that should *always* be passed on down
|
||||
the chain. These are interrupt which may commonly have multiple drivers
|
||||
attached.
|
||||
|
||||
The following interrupts should always be passed on (return value of 0)
|
||||
|
||||
IRQ_TIMER0
|
||||
IRQ_TIMER1
|
||||
IRQ_VSYNC
|
||||
IRQ_FLYBACK
|
||||
IRQ_PODULE
|
||||
|
||||
IRQ_CLOCK (RC7500)
|
||||
|
||||
The following interrupts are recommended to be passed on
|
||||
|
||||
IRQ_DMACH0
|
||||
IRQ_DMACH1
|
||||
IRQ_DMACH2
|
||||
IRQ_DMACH3
|
||||
IRQ_DMASCH0
|
||||
IRQ_DMASCH1
|
||||
|
||||
IRQ_SDMA (RC7500)
|
||||
|
||||
All other interrupts are not expected to be shared and may be claimed
|
||||
when serviced. Stray IRQ handlers may or may not be attached to the end
|
||||
of these irq chains.
