From a2663ea4fc9d18cb8000c97ed92c3c668eda8e04 Mon Sep 17 00:00:00 2001 From: wdenk Date: Sun, 7 Dec 2003 18:32:37 +0000 Subject: * Patches by David Müller, 14 Nov 2003: - board/mpl/common/common_util.c * implement support for BZIP2 compressed images * various cleanups (printf -> puts, ...) - board/mpl/common/flash.c * report correct errors to upper layers * check the erase fail and VPP low bits in status reg - board/mpl/vcma9/cmd_vcma9.c - board/mpl/vcma9/flash.c * various cleanups (printf -> puts, ...) - common/cmd_usb.c * fix typo in comment - cpu/arm920t/usb_ohci.c * support for S3C2410 is missing in #if line - drivers/cs8900.c * reinit some registers in case of error (cable missing, ...) - fs/fat/fat.c * support for USB/MMC devices is missing in #if line - include/configs/MIP405.h - include/configs/PIP405.h * enable BZIP2 support * enlarge malloc space to 1MiB because of BZIP2 support - include/configs/VCMA9.h * enable BZIP2 support * enlarge malloc space to 1MiB because of BZIP2 support * enable USB support - lib_arm/armlinux.c * change calling convention of ARM Linux kernel as described on http://www.arm.linux.org.uk/developer/booting.php MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * Patch by Thomas Lange, 14 Nov 2003: Split dbau1x00 into dbau1000, dbau1100 and dbau1500 configs to support all these AMD boards. * Patch by Thomas Lange, 14 Nov 2003: Workaround for mips au1x00 physical memory accesses (the au1x00 uses a 36 bit bus internally and cannot access physical memory directly. Use the uncached SDRAM address instead of the physical one.) --- include/asm-mips/addrspace.h | 12 ++++++++++++ 1 file changed, 12 insertions(+) (limited to 'include/asm-mips') diff --git a/include/asm-mips/addrspace.h b/include/asm-mips/addrspace.h index 0d1bf3246d..1fd00ccba9 100644 --- a/include/asm-mips/addrspace.h +++ b/include/asm-mips/addrspace.h @@ -40,6 +40,18 @@ #define PHYSADDR(a) ((a) & 0x1fffffff) #endif +/* + * Returns the uncached address of a sdram address + */ +#ifndef __ASSEMBLY__ +#ifdef CONFIG_AU1X00 +/* We use a 36 bit physical address map here and + cannot access physical memory directly from core */ +#define UNCACHED_SDRAM(a) (((unsigned long)(a)) | 0x20000000) +#else /* !CONFIG_AU1X00 */ +#define UNCACHED_SDRAM(a) PHYSADDR(a) +#endif /* CONFIG_AU1X00 */ +#endif /* __ASSEMBLY__ */ /* * Map an address to a certain kernel segment */ -- cgit
