As powerpc can actually perform\nnon-identity mapping between physical & virtual addresses we can't\nsimply make use of the generic phys_to_virt() & virt_to_phys()\nfunctions. However since map_physmem() already effectively implemented\nthe same thing as virt_to_phys() we can simply implement virt_to_phys()\ninstead of map_physmem() & use the generic map_physmem(). We also drop\nthe no-op unmap_physmem().\n\nThis has only been build-tested, feedback from architecture maintainers\nis welcome.\n\nSigned-off-by: Paul Burton <paul.burton@imgtec.com>\nCc: Wolfgang Denk <wd@denx.de>\n---\n\n arch/powerpc/include/asm/io.h | 25 +++++--------------------\n 1 file changed, 5 insertions(+), 20 deletions(-)", "diff": "diff --git a/arch/powerpc/include/asm/io.h b/arch/powerpc/include/asm/io.h\nindex a54fc46..34fbfdf 100644\n--- a/arch/powerpc/include/asm/io.h\n+++ b/arch/powerpc/include/asm/io.h\n@@ -282,18 +282,7 @@ static inline void out_be32(volatile unsigned __iomem *addr, u32 val)\n #define setbits_8(addr, set) setbits(8, addr, set)\n #define clrsetbits_8(addr, clear, set) clrsetbits(8, addr, clear, set)\n \n-/*\n- * Given a physical address and a length, return a virtual address\n- * that can be used to access the memory range with the caching\n- * properties specified by \"flags\".\n- */\n-#define MAP_NOCACHE\t(0)\n-#define MAP_WRCOMBINE\t(0)\n-#define MAP_WRBACK\t(0)\n-#define MAP_WRTHROUGH\t(0)\n-\n-static inline void *\n-map_physmem(phys_addr_t paddr, unsigned long len, unsigned long flags)\n+static inline void *phys_to_virt(phys_addr_t paddr)\n {\n #ifdef CONFIG_ADDR_MAP\n \treturn addrmap_phys_to_virt(paddr);\n@@ -301,14 +290,7 @@ map_physmem(phys_addr_t paddr, unsigned long len, unsigned long flags)\n \treturn (void *)((unsigned long)paddr);\n #endif\n }\n-\n-/*\n- * Take down a mapping set up by map_physmem().\n- */\n-static inline void unmap_physmem(void *vaddr, unsigned long flags)\n-{\n-\n-}\n+#define phys_to_virt phys_to_virt\n \n static inline phys_addr_t virt_to_phys(void * vaddr)\n {\n@@ -318,5 +300,8 @@ static inline phys_addr_t virt_to_phys(void * vaddr)\n \treturn (phys_addr_t)((unsigned long)vaddr);\n #endif\n }\n+#define virt_to_phys virt_to_phys\n+\n+#include <asm-generic/io.h>\n \n #endif\n", "prefixes": [ "U-Boot", "16/27" ] }
