[oe] Problems building a kernelmodule for OE

[Henk Geraads]

Hi Stanislav,

Found the problem with __LINUX_ARM_ARCH__!
the "-march=armv5t"  in the makefie compiler line did mess up things!!
the include of the "pxa-regs.h" and "gpio.h" solved the other problem.

Now I've got strange error's from the linker;
	make[2]: *** [/home/henk/SystemDev/module/cfi-ktst/cfi-mod.ko] Error 1
	make[1]: *** [modules] Error 2
	make: *** [default] Error 2
	arm-angstrom-linux-gnueabi-ld: unrecognized option '-Wl,-rpath-link,/home/armcore/oe/build/tmp/angstrom/staging/arm-angstrom-linux-gnueabi/lib'
	arm-angstrom-linux-gnueabi-ld: use the --help option for usage information
	make[2]: *** [/home/henk/SystemDev/module/cfi-ktst/cfi-mod.ko] Error 1
	make[1]: *** [modules] Error 2
	make: *** [default] Error 2

I thought linker option's are very common?

Henk
