* Use CONFIG_MP instead of CONFIG_NUM_CPUS to match 85xx * Introduce determine_mp_bootpg() helper. We'll need this to address a bug introduced in v2009.03 with 86xx MP booting. We have to make sure to reserve the region of memory used for the MP bootpg() so other u-boot code doesn't use it. * Added dummy versions of cpu_reset(), cpu_status() & cpu_release() to allow cmd_mp.c to build and work. In the future we should look at implementing all these functions. This could be common w/85xx if we use spin tables on 86xx. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
