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
52 on MicroBlaze systems without a barrel shifter.

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
74 again. You have been warned!
