* 85xx: Introduce determine_mp_bootpg() helper.Kumar Gala2009-04-011-2/+2
| | | | | | | | | | | | Match determine_mp_bootpg() that was added for 86xx. We 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. Also added a comment about how cpu_reset() is dealing w/an errata on early 85xx MP HW. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* 85xx: Add cpu_mp_lmb_reserve helper to reserve boot pageKumar Gala2008-03-261-0/+1
| | | | | | | Provide a board_lmb_reserve helper function to ensure we reserve the page of memory we are using for the boot page translation code. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* 85xx: Update multicore boot mechanism to ePAPR v0.81 specKumar Gala2008-03-261-0/+11
| | | | | | | | | | | | The following changes are needed to be inline with ePAPR v0.81: * r4, r5 and now always set to 0 on boot release * r7 is used to pass the size of the initial map area (IMA) * EPAPR_MAGIC value changed for book-e processors * changes in the spin table layout * spin table supports a 64-bit physical release address Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* 85xx: Added support for multicore boot mechanismKumar Gala2008-03-261-0/+8
Added the cpu command that provides a generic mechanism to get status, reset, and release secondary cores in multicore processors. Added support for using the ePAPR defined spin-table mechanism on 85xx. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
