Yeah, or treo-common.c in case you'd want to split it into core file + model
files. But treo.c/palm(smart)phone.c (?) seems more ok. I dont like the idea of
splitting the code into more files (one big, and many small).

on other things, by the api. Are there? I would guess there is
something to do about the '.config' switch and two or three make files.
Or am I wrong here and it's more complicated than it looks to me?

By the way, freescale answered to my request for that "API document=20
MOT-SFS-IAPI-SAS-001 (Version 0.4)":=20

I didn't get why they are doing it, but that might be the reason this
api is not included in the mainline/denx kernel.
Thanks again and I will have a closer look on porting that api :-)

image, reboots and then users get a rescue system trough ssh. From this
point, the user can flash a new kernel and initrd which will ignore the
'root=...' the kernel argument.
All theses steps are done without serial console. Due to this wrong
memory size setting, this can't be done on ss4000e. One has to find a
serial cable (not always easy) and then not forget to every time add
the 'mem=...' stuff. Moreover, it's more fool proof. A rescue with
memory limited to 256M will always work.
I hope this will help you to ack or nack the patch.
Thanks,
Arnaud

Please look at the above and realise that cpu_die() is only ever defined
in case that HOTPLUG_CPU is defined. So there is nothing to discard if
HOTPLUG_CPU equals to n.
And just to repeat myself....
The only correct use of __cpu* annotation is for function/data that is
used with or without HOTPLUG_CPU equals to y.
Which is NOT the case for cpu_die().
The __cpu* annotation is not a replacement for ifdeffed out code that is
not relevant for the non-HOTPLUG_CPU case.
