121 | help | |
122 | MPC860 CPUs, prior to Rev C have some bugs in the silicon, which | |
123 | require workarounds for Linux (and most other OSes to work). If you | |
124 | get a BUG() very early in boot, this might fix the problem. For | |
125 | more details read the document entitled "MPC860 Family Device Errata | |
c8a55f3d | 126 | Reference" on Freescale's website. This option also incurs a |

135 | help | |
136 | This enables a workaround for erratum CPU15 on MPC8xx chips. | |
137 | This bug can cause incorrect code execution under certain | |
138 | circumstances. This workaround adds some overhead (a TLB miss | |
139 | every time execution crosses a page boundary), and you may wish | |
140 | to disable it if you have worked around the bug in the compiler | |
141 | (by not placing conditional branches or branches to LR or CTR | |
142 | in the last word of a page, with a target of the last cache | |
143 | line in the next page), or if you have used some other | |
144 | workaround. | |
