Add support to disable cpu's in multicore processors 2010-01-27T05:17:49+00:00 Kumar Gala galak@kernel.crashing.org 2010-01-12T17:42:43+00:00 4194b3668a93eee18dd1f7eb1309ca7b05003aa7 Add a disable sub-command to the cpu command that allows for disabling cores in multicore processors. This can be useful for systems that are using multicore chips but aren't utilizing all the cores as a way to reduce power and possibly improve performance. Also updated an added missing copyright.

86xx: Cleanup MP support 2009-04-01T20:29:44+00:00 Kumar Gala galak@kernel.crashing.org 2009-04-01T04:02:38+00:00 7649a590b53ee548f41428bf20780f74ce9fc099 * 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>

powerpc: change 86xx SMP boot method 2008-11-04T16:58:50+00:00 Becky Bruce becky.bruce@freescale.com 2008-11-03T21:44:01+00:00 1266df887781c779deaf6d05eea2ef90a470cb34 We put the bootpg for the secondary cpus into memory and use BPTR to get to it. This is a step towards converting to the ePAPR boot methodology. Also, the code is written to deal properly with more than 4GB of RAM. Signed-off-by: Becky Bruce <becky.bruce@freescale.com>
