7 menu "Platform options"
10 default PLATFORM_MICROBLAZE_AUTO
12 Choose which hardware board/platform you are targeting.
14 config PLATFORM_GENERIC
17 Choose this option for the Generic platform.
22 bool "Use self modified code for intc/timer"
23 depends on EXPERIMENTAL && NO_MMU
26 This choice enables self-modified code for interrupt controller
30 bool "Use self modified code for intc"
34 This choice enables self-modified code for interrupt controller.
37 bool "Use self modified code for timer"
41 This choice enables self-modified code for timer.
43 config OPT_LIB_FUNCTION
44 bool "Optimalized lib function"
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.
55 bool "Optimalized lib function ASM"
56 depends on OPT_LIB_FUNCTION && (XILINX_MICROBLAZE0_USE_BARREL = 1)
59 Allows turn on optimalized library function (memcpy and memmove).
60 Function are written in asm code.
