I have two questions regarding this patchset: - considering that BMIPS4350 has a shared TLB, is it still working fine? I must say that I have not yet tested on e.g: BCM6358 - there a couple of places in the code where we have: #if defined (CONFIG_BMIPS_4350) || defined (CONFIG_BMIPS_4380) ... do something #elif defined(CONFIG_BMIPS_4380) can we turn this into a #if BMIPS43xx case .. #endif #if BMIPS5000 ... #endif to allow a single image supporting both BMIPS43xx and BMIPS5000? By the time we are initializing the CPUs for SMP, we should be able to use runtime checks on the BMIPS CPU variant. Thanks. -- Florian
