183 | This special driver allows you to temporary use NMI debugger port | |
184 | as a normal console (assuming that the port is attached to KGDB). | |
185 | ||
186 | Unlike KDB's disable_nmi command, with this driver you are always | |
187 | able to go back to the debugger using KGDB escape sequence ($3#33). | |
188 | This is because this console driver processes the input in NMI | |
189 | context, and thus is able to intercept the magic sequence. | |
190 | ||
191 | Note that since the console interprets input and uses polling | |
192 | communication methods, for things like PPP you still must fully | |
193 | detach debugger port from the KGDB NMI (i.e. disable_nmi), and | |
194 | use raw console. | |

1215 | This driver is for PCH(Platform controller Hub) UART of Intel EG20T | |
1216 | which is an IOH(Input/Output Hub) for x86 embedded processor. | |
1217 | Enabling PCH_DMA, this PCH UART works as DMA mode. | |

8249f743 TM |
1219 | This driver also can be used for LAPIS Semiconductor IOH(Input/ |
1220 | Output Hub), ML7213, ML7223 and ML7831. | |
1221 | ML7213 IOH is for IVI(In-Vehicle Infotainment) use, ML7223 IOH is | |
1222 | for MP(Media Phone) use and ML7831 IOH is for general purpose use. | |
1223 | ML7213/ML7223/ML7831 is companion chip for Intel Atom E6xx series. | |
1224 | ML7213/ML7223/ML7831 is completely compatible for Intel EG20T PCH. | |
