* [PATCH 12/15] [POWERPC] Add mpc52xx_restart(), mpc52xx_halt(), mpc52xx_power_off().

You should not include this file. And you actually don't use any of the

Not sure about this - if you want to find the root node, then you should
probably do that explicitly.

Can you explain (a) further -- I'm assuming the BAT mapping is 1:1
for that region?
For (b) it looks like:
* 40x, 44x, fsl-booke compare against TASK_SIZE in their software
handlers.
* 8xx still tests 0x80000000
* 6xx (603) compares against KERNELBASE
It would seem like we should set the default on 8xx & PReP to
0x80000000 and not allow it to be modified since that will break the
world and for everything else move it to match KERNELBASE. Any
issues with that?

For as much as this has been discussed in the past,
I don't know why the 8xx doesn't check KERNEL_BASE
and work properly with the options. There is no reason
this can't work. The history is I wrote the tlb handlers
to test the MS bit due to a hardcoded address, not that
the address is hardcoded because I wanted to just
test a bit. Unlike PReP, there is no reason to
disallow modification, if this test was changed.
Thanks.

How about

The proper value is neither :-)
It should be compared against PAGE_OFFSET.

In theory, yes -- but in practice the odds of this particular heuristic
choosing an unsuitable address seem slim.

Sorry, I was being a bit too pendantic with respect to the distinction
between link and load address.

No, the "hoops" (which I don't think are sufficiently complicated to
warrant such a name) are to address a generic issue with the bootwrapper
-- it wants to put the kernel at zero. It'd be really nice if, in the
absense of a vmlinux_alloc method, the generic code would do an ordinary
malloc() if there's not enough room at zero.

I think this heuristic would work in most situations, so if we do add a
manual override it should be an override, and not something that
everybody has to put up with.

It's a source of potential issues, but I think "asking for trouble" is
exaggerating somewhat.

dtc now supports the syntax "fsl,cm5200", "generic-mpc5200" so you
don't need the ugly inline \0.

First, this is the old flash binding, please use the new one.
Second, is the flash really part of the SoC?

Surely there must be some sort of bus controller above these devices..?

* Re: Where are inb/outb macros?

inb/outb could be used from the usr space on x86 class PC-computer to access
to io ports this is what i assume that you are trying
You need to compile the program with -O option (expantion of Inline function
)
To perform io operation on ports ioprem/iopl system call must be used (To
get permissio to perform io operation)
Program must run as root
on non 86 platform try using /dev/port device file in the application

Hmmm....
Both this patch and the CM5200 support patch (#6 in your series) are
pretty much clones of lite5200.c. I don't think this is the right
approach. Don't duplicate code in this way. Determine the common
bits and put them in a common place to be usable by any 5200 board
port.
It might even be better just to add a platform that matches on
compatible='mpc5200-generic' which is usable for mpc5200 boards that
don't need any custom setup by the kernel at platform setup time.
(which will probably be most 5200 boards).
More comments below. (And, yes, I realize that all these comments
also apply to lite5200.c).

Hmmm; it's looking like every 52xx board is adding this boilerplate
"depends" line... That's probably sub-optimal. (More a general
thought than a comment on your patch)

Are you *sure* you want this? You should only be touching port_config
if firmware fails to set it up correctly. Don't blindly copy what was
done for the lite5200.
Lite5200 touches it because firmware does *not* do the right thing at
the moment.

Unnecessary cast, and add 'const' to 'fp' declaration.

Use NULL instead of 0 for pointer tests. 'if (fp)' is also good style here.

Drop all this ROOT_DEV code. It's brain damaged.

Drop the pr_debug line and the setting of 'model' above. The platform
setup call prints out the name of the platform regardless.
