47 | Allows turn on optimalized library function (memcpy and memmove). | ||
48 | They are optimized by using word alignment. This will work | ||
49 | fine if both source and destination are aligned on the same | ||
50 | boundary. However, if they are aligned on different boundaries | ||
51 | shifts will be necessary. This might result in bad performance | ||

66 | help | ||
67 | Allows the editing of auto-generated platform settings from | ||
68 | the Kconfig.auto file. Obviously this does not change the | ||
69 | underlying hardware, so be very careful if you go editing | ||
70 | these settings. | ||
71 | |||
72 | Also, if you enable this, and edit various Kconfig.auto | ||
73 | settings, YOUR CHANGES WILL BE LOST if you then disable it | ||
