[PATCH 00/10] Raspberry Pi 2 (BCM2836) SMP support

From: Pavel Pisa The series implements Raspberry Pi 2 (BCM2836) SMP support. The first two patches modify ARM Cortex-A common CP15 support to expose clean by level cache operations to the BSP code. Clean and invalidation of L1 cache is required when the secondary CPU is booted. But the secondary

[PATCH 01/10] bsps/arm: use defines for cache type register format field.

From: Pavel Pisa The change documents meaning of codes and opens well defined way to use cache type format for cache examination/debugging outside of arm-cp15.h file. --- c/src/lib/libcpu/arm/shared/include/arm-cp15.h | 39 -- 1 file changed, 30 insertions(+), 9 deletions

[PATCH 02/10] bsps/arm: remove lock in arm_cp15_set_translation_table_entries().

From: Pavel Pisa Protection by rtems_interrupt_disable() is incompatible with SMP build. Actual page table entries manipulation function does not need locking and disabling cache and can be run concurrently even on multiple CPUs as long as changes do not modify same region. If the function is cal
