-gerrit commit 13953087baa0032722a55216e02ddb568e3821a0 Author: Kyösti Mälkki <[email protected]> Date: Tue Nov 22 19:44:45 2011 +0200 Bootblock does not need a unique boot_cpu() Detection of a CPU being a BSP CPU is not dependent of the existence of northbridge and/or southbridge init code in the bootblock. Even if CONFIG_LOGICAL_CPUS==0, boot_cpu() can get executed on an AP CPU of a hyper-threading CPU and needs to return actual BSP bit from MSR.
