You need to use 1025_enable_CAR_init_cpus_get_apicid_base.diff.
The 1025_enable_CAR.diff missed init_cpus.

YH,
I've applied your patch, and started porting some of the bits over from
the s2895 code, however it looks like I'm missing
"cpu/amd/model_fxx/init_cpus.c" or wherever 'init_cpus()' is defined.
The cleanups look pretty damned good so far though... still trying to
get building to work...
Kudos anyawys ;)

San,
Please check the patch for CAR
1. add cpu_init_detectedx, it is passed from cache_as_ram.inc and
to amd64_main...
2. add init_cpus for CAR ---more readable
3. post_cache_as_ram ---> make cache_as_ram_auto.c shorter....
4. renable get_apicid_base, in case some one still want BSP apid id
=0 but other cpu is lifted.

killing get_apicid_base looks like a bug.
But as far as I can tell everything that is gone is now unnecessary.
Okay... so what replace start_other_cores()?.. In CAR mode, do I make a
call to 'do_k8_init_and_stop_secondaries()'?
That code itself wont build due to the following in
'k8_init_and_stop_secondaries()':
if (init_detected) {
asm volatile ("jmp __cpu_reset");
}
because in CAR configs, arch/i386/lib/cpu_reset.inc is not included. On
this particular issue, I'm happy to wait for YH's fixes.
I just think if we're going to deprecate a core call like that, there
should be some documentation on *why* it was removed, as well as some
indication as to where the behavior got 'moved' to.
It just makes things a lot easier for thoes of us that are either
ramping up, or trying to maintain things..
Thanks Eric ;)
