It also changes %p debug statements in various places. I think they get in
the way of diffs when you have log files to compare. I don't want to see the
allocation differences most of the time. I turned most of them into NULL
checks. If they were supposed to be "Where are we in device allocation?"
checks, we could make them into that too.
It's a work-in-progress. Comments welcome.
I think most of the changes are self explanatory, but this one might not be:
If you are reading all the BARs from a device, and you come to a 64-bit BAR.
No matter why you skip it, you should skip it as a 64-bit BAR, and not try to
read the upper half as the next 32-bit BAR.
Because of that, set the 64-bit flag IORESOURCE_PCI64 early, and don't clear
it on return.

workarounds are better than instant reboots, mangle the code so that it
only switches stacks and flushes the cache.
There are two genuine fix in there as well:
We have to switch %esp before CAR is disabled. That way, the stack is
always valid.
And one of the nastier bugs easily happening in C: We had a pointer to a
const struct, but we wanted a const pointer to a struct. This kills the
(correct) warning about that code.
Many thanks to Corey for testing countless iterations of that code.

dev_phase4 will call compute_allocate. This is an early pass at
making the device tree code a little more readable. We have done a
pass on the stage2 code and are comfortable with phases 1-3 and 5-6;
phase 4 is the phase that is really tough to follow. We are working
on cleaning that up today.
This change tested and working on dbe62.
We are well aware that as more complex targets appear this code
may break on them. At the same time, we are determined to untangle the
thicket of code in phase 4, since this code has been a source of
confusion for several years now.
There used to be a recursion: compute_allocate_resource would ALWAYS
call read_resources, which would in turn call compute_allocate_resource.
We are attempting to resolve this in a clearer manner.

have a CAR area outside the usual RAM area. For those processors, we
have to implement a stack copying and switching mechanism. Since gcc
can't be told that the stack just moved, split stage1_main() into
stage1_phase1() and stage1_phase2() and stage1_phase3().
stage1_phase1() is the new entry point in stage1 and will handle
everything up to the point where we want to disable CAR.
Switching the stack, disabling CAR and handling other tasks related to
the stack switch (printk buffer move) is all wrapped in the
stage1_phase2() function.
stage1_phase2() calls disable_car() which then calls stage1_phase3().
stage1_phase3() is the former second half of stage1_main().
Notes about this patch:
- Code flow is almost unchanged for Qemu, K8 and Geode. No extensive new
testing required.
- We can support stack-keeping and stack-relocating architectures at the
same time, so C7 is definitely supportable
- The comment in stage1_phase2 says "some of this is not yet done". That
refers to the nonexisting code for stack switching on C7.
- "Minimal changes, maximum benefit".
