I have issues with a custom board with smsc911x. u-boot detects the chip, but the kernel does not.
To help me debugging the issue, I recompiled my kernel to add the smsc911x as a kernel module but now, I want to change the debug level in the file smsc911x.h. In my yocto directory there is a lot of files named smsc911x.h ( I uses the gumstix repo ), all in the build/tmp subdirectory. In which directory we have to change the debug level in the file ?
