[U-Boot] [PATCH 06/15] Moved generic (triple fault) reset code

[Graeme Russ]

Moved from interrupts.c to cpu.c and made into a weak function to allow
vendor specific override

Signed-off-by: Graeme Russ <graeme.russ at gmail.com>

Vendor specific CPU reset (like the AMD SC520 MMCR reset) can now be
added to the vendor specific code without the need to remember to #undef
usage of the generic method and if you forget to include your custom
reset method, you will always get the default
