I'm trying to build minimalistic kernel for OMAP3 EVM based on PSP-02.01.02.09. The goal is to minimize boot time. However kernel fails to build without "Support for hot-pluggable devices" enabled:
MODPOST vmlinux.o
WARNING: modpost: Found 1 section mismatch(es).
To see full details build your kernel with:
'make CONFIG_DEBUG_SECTION_MISMATCH=y'
GEN .version
CHK include/linux/compile.h
UPD include/linux/compile.h
CC init/version.o
LD init/built-in.o
LD vmlinux
`gpio_twl4030_remove' referenced in section `.devinit.text' of drivers/built-in.o: defined in discarded section `.devexit.text' of drivers/built-in.o
`omap2_onenand_remove' referenced in section `.data' of drivers/built-in.o: defined in discarded section `.devexit.text' of drivers/built-in.o
`omap2_onenand_shutdown' referenced in section `.data' of drivers/built-in.o: defined in discarded section `.devexit.text' of drivers/built-in.o
make: *** [vmlinux] Error 1
Is this behavior intentional?
