* microblaze: Fix __muldi3 function for little-endian.Michal Simek2011-01-032-121/+60
| | | | | | | | | __muldi3 was written for big endian platforms. Code contained half word read/write instructions which are not compatible with little endian cpu. Asm __muldi3 implementation is replaced by C version. Signed-off-by: Michal Simek <monstr@monstr.eu>
* arch/microblaze: Remove unnecessary semicolonsJoe Perches2010-11-151-1/+1

* microblaze: Support C optimized lib functions for little-endianMichal Simek2010-10-212-6/+60
| | | | | | | | Optimized C library functions can rapidly speedup the kernel. memset doesn't need to be optimized because there is no difference in behavior on little/big endian cpu. Signed-off-by: Michal Simek <monstr@monstr.eu>
* microblaze: Separate library optimized functionsMichal Simek2010-10-213-15/+46
| | | | | | memcpy/memmove/memset Signed-off-by: Michal Simek <monstr@monstr.eu>
* microblaze: Add libgcc function directly to kernelMichal Simek2010-10-2111-0/+607
| | | | | | Replaced libgcc functions with asm optimized implementation. Signed-off-by: Michal Simek <monstr@monstr.eu>
* microblaze: Support word copying in copy_tofrom_userMichal Simek2010-04-011-14/+25
| | | | | | | | Word copying is used only for aligned addresses. Here is space for improving to use any better copying technique. Look at memcpy implementation. Signed-off-by: Michal Simek <monstr@monstr.eu>
* microblaze: Adding likely macrosMichal Simek2010-04-012-8/+9
| | | | | | | On the base on GCOV analytics is helpful to add likely/unlikely macros. Signed-off-by: Michal Simek <monstr@monstr.eu>
* microblaze: Add .type and .size to ASM functionsMichal Simek2010-04-012-1/+11
| | | | | | Cachegrind analysis need this fix to be able to log asm functions. Signed-off-by: Michal Simek <monstr@monstr.eu>
* microblaze: uaccess: Unify __copy_tofrom_userMichal Simek2010-04-011-1/+1
| | | | | | Move to generic location. Signed-off-by: Michal Simek <monstr@monstr.eu>

* microblaze: Simple __copy_tofrom_user for noMMUJohn Williams2009-12-141-0/+7
| | | | | | | | This is first patch which clear part of uaccess.h. uaccess.h will be clear later. Signed-off-by: John Williams <john.williams@petalogix.com> Signed-off-by: Michal Simek <monstr@monstr.eu>

* microblaze: use the generic lib/checksum.cRemis Lima Baima2009-07-062-173/+1
| | | | | | | | The microblaze checksum code is mostly identical to the asm-generic+lib version, so use that instead. Signed-off-by: Remis Lima Baima <remis.developer@googlemail.com> Signed-off-by: Michal Simek <monstr@monstr.eu>

* microblaze: clean up checksum.cArnd Bergmann2009-05-211-11/+20
| | | | | | | | | | | | | | | | This changes the function prototypes in the checksum code to have the usual prototypes, typically by turning int arguments into __wsum. Also change csum_partial_copy_from_user() to operate on the right address space and export ip_fast_csum, which is used in modular networking code. The new version is now sparse-clean including endianess checks. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Michal Simek <monstr@monstr.eu>
* microblaze: remove cacheable_memcpyArnd Bergmann2009-05-211-5/+0
| | | | | | | | This function is neither declared nor used anywhere outside of ppc32, so remove it from microblaze. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Michal Simek <monstr@monstr.eu>
