What is the intention of CONFIG_CPU_HAS_WB? On an RM7000, am I better
off doing a pipeline flush (the nops in wbflush.h) or a sync
instruction? Also, any guidance on whether I should go out and ensure
writes have completed in PCI host adapters and bridges, or whether
this is excessive paranoia.
Thanks, Kevin -- |
