davinci: Move IO device mapping macros from io.h to hardware.h
This patch takes out IO mapping macros from mach/io.h and puts them in mach/hardware.h avoiding need to include mach/io.h in various files such as serial.h, vmalloc.h etc. The main reason to avoid inclusion of mach/io.h is, when default in/out macros are overridden by machine specific functions (e.g., in case of PCI I/O), they result into linker error. An example snippet and error snapshot is listed below. Following code in mach/io.h: #define inl(p) my_inl() static inline unsigned int my_inl(unsigned int addr) { if (IS_PCI_IO(addr)) return pci_inl (); else return le32_to_cpu(__raw_readl(__typesafe_io(addr))); } leads to error: LD arch/arm/boot/compressed/vmlinux arch/arm/boot/compressed/misc.o: In function `my_inl': misc.c:(.text+0x2744): undefined reference to `pci_inl' make[2]: *** [arch/arm/boot/compressed/vmlinux] Error 1 This is because mach/io.h gets included in arch/arm/boot/compressed/misc.c through mach/serial.h but pci.c file, which defines 'pci_inl' doesn't get built into compressed vmlinux.
