C)" help MPC860 CPUs, prior to Rev C have some bugs in the silicon, which require workarounds for Linux (and most other OSes to work). If you get a BUG() very early in boot, this might fix the problem. For more details read the document entitled "MPC860 Family Device Errata Reference" on Freescale's website. This option also incurs a performance hit. If in doubt, say N here. config 8xx_CPU15 bool "CPU15 Silicon Errata" default y help This enables a workaround for erratum CPU15 on MPC8xx chips. This bug can cause incorrect code execution under certain circumstances. This workaround adds some overhead (a TLB miss every time execution crosses a page boundary), and you may wish to disable it if you have worked around the bug in the compiler (by not placing conditional branches or branches to LR or CTR in the last word of a page, with a target of the last cache line in the next page), or if you have used some other workaround.
