2024-10-28hexagon: simplify asm/io.h for !HAS_IOPORTArnd Bergmann
Hexagon fails to build after the final patch that makes CONFIG_HAS_IOPORT optional: In file included from arch/hexagon/include/asm/io.h:328: include/asm-generic/io.h:854:18: error: static declaration of 'ioread8' follows non-static declaration 854 | static inline u8 ioread8(const volatile void __iomem *addr) | ^ include/asm-generic/io.h:853:17: note: expanded from macro 'ioread8' 853 | #define ioread8 ioread8 | ^ include/asm-generic/iomap.h:29:21: note: previous declaration is here 29 | extern unsigned int ioread8(const void __iomem *); | ^ As it turns out, most of its asm/io.h and lib/io.c files is redundant now, and just removing all that makes it build again. As with the other architectures, defining the __raw_readl()/__raw_writel() type functions instead of the non-__raw ones is better here for consistency. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
