Hi, I found some definitions of static inline functions in directory inside asm-/include and asm-generic/include. I am able to find them inside the asm/include of linux kernel, gcc as well u-boot. What is the significance of them ? If given a circumstance of porting a bootloader such as u-boot to OpenRISC platform, is it required to define the functions contained in files such as types.h, bitops.h, byteorder.h, string.h, posix_types.h, etc of order platforms. The common code files seem to include them. Are these definitions dependent on the compiler ? Or these an arch dependent interface level definitions. Any pointers would be helpful. Thanks and Regards, Ram
