171 This special driver allows you to temporary use NMI debugger port
172 as a normal console (assuming that the port is attached to KGDB).
174 Unlike KDB's disable_nmi command, with this driver you are always
175 able to go back to the debugger using KGDB escape sequence ($3#33).
176 This is because this console driver processes the input in NMI
177 context, and thus is able to intercept the magic sequence.
179 Note that since the console interprets input and uses polling
180 communication methods, for things like PPP you still must fully
181 detach debugger port from the KGDB NMI (i.e. disable_nmi), and
182 use raw console.

1243 This driver is for PCH(Platform controller Hub) UART of Intel EG20T
1244 which is an IOH(Input/Output Hub) for x86 embedded processor.
1245 Enabling PCH_DMA, this PCH UART works as DMA mode.
1247 This driver also can be used for LAPIS Semiconductor IOH(Input/
1248 Output Hub), ML7213, ML7223 and ML7831.
1249 ML7213 IOH is for IVI(In-Vehicle Infotainment) use, ML7223 IOH is
1250 for MP(Media Phone) use and ML7831 IOH is for general purpose use.
1251 ML7213/ML7223/ML7831 is companion chip for Intel Atom E6xx series.
