arm: mach-axxia: kexec_reinit to set L3 CACHE shutdown
Shut down to flush L3 cache for KEXEC to avoid the hung issue for capture kernel booting, since for ARM capture kernel just one CPU allowed to boot, and no L3 cache coherency issue existed for SMP situation, so just shut down the flush to L3 CACHE. The function calling relationship like below: kernel_kexec machine_kexec kexec_reinit flush_l3 Signed-off-by: Xulin Sun <xulin.sun@windriver.com> [Quanyang: add a new function shutdown_l3 to shutdown the l3 cache in the kexec routine.] Signed-off-by: Quanyang Wang <quanyang.wang@windriver.com> Signed-off-by: Bruce Ashfield <bruce.ashfield@gmail.com>
