From babba4f11379fb3804de802a3d0bc6b96c59d547 Mon Sep 17 00:00:00 2001 From: David Daney Date: Fri, 23 Jul 2010 10:57:51 -0700 Subject: MIPS: Octeon: HOTPLUG_CPU fixes. * Rename camel-case InitTLBStart_addr to octeon_bootloader_entry_addr. * Convert calls to cvmx_read64_uint32(), to simple pointer dereferences. * Set proper ebase. * Don't confuse coreid and cpu numbers. * Try to maintain consistent bootloader coremask. * Update the signature and boot_init_vector of supported bootloaders.
