* CRISv32: Add arch optimized strcmp.Jesper Nilsson2009-06-10
| | | | | | | | Add an optimized strcmp for CRISv32. This improves strcmp performance with about 25% when comparing a 55 character string with itself. Signed-off-by: Edgar Iglesias <edgar@axis.com> Acked-by: Jesper Nilsson <jesper.nilsson@axis.com>
* [CRIS] Move header files from include to arch/cris/include.Jesper Nilsson2008-10-29
| | | | | | | Change all users of header files to correct path. Remove some unneeded headers for arch-v32. Signed-off-by: Jesper Nilsson <jesper.nilsson@axis.com>
* cris: correct usage of __user for copy to and from user space in ↵Jesper Nilsson2008-03-04
| | | | | | | | | | | | | | | | | lib/usercopy and uaccess.h Function __copy_user_zeroing in arch/lib/usercopy.c had the wrong parameter set as __user, and in include/asm-cris/uaccess.h, it was not set at all for some of the calling functions. This will cut the number of warnings quite dramatically when using sparse. While we're here, remove useless CVS log and correct confusing typo.

* CRIS: Import string.c (memcpy) from newlib: fixes compile error with gcc 4Jesper Nilsson2008-03-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adrian Bunk reported another compile error with a SVN head GCC: ... CC arch/cris/arch-v10/lib/string.o /home/bunk/linux/kernel-2.6/git/linux-2.6/arch/cris/arch-v10/lib/string.c:138: error: lvalue required as increment operand /home/bunk/linux/kernel-2.6/git/linux-2.6/arch/cris/arch-v10/lib/string.c:138: error: lvalue required as increment operand /home/bunk/linux/kernel-2.6/git/linux-2.6/arch/cris/arch-v10/lib/string.c:139: error: lvalue required as increment operand ... This is due to the use of the construct: *((long*)dst)++ = lc; Which isn't legal since casts don't return an lvalue. The solution is to import the implementation from newlib, which is continually autotested together with GCC mainline, and uses the construct: *(long *) dst = lc; dst += 4; Since this is an import of a file from newlib, I'm not touching the formatting or correcting any checkpatch errors. As for the earlier fix for memset.c, even if the two files for CRIS v10 and CRIS v32 are identical at the moment, it might be possible to tweak the CRIS v32 version. Thus, I'm not yet folding them into the same file, at least not until we've done some research on it.

The solution is to import the implementation from newlib, which is continually autotested together with GCC mainline, and uses the construct: *(long *) dst = lc; dst += 4; With this change, the generated code actually shrinks 76 bytes since gcc notices that it can use autoincrement for the move instruction in CRIS. text data bss dec hex filename 304 0 0 304 130 memset.old.o text data bss dec hex filename 228 0 0 228 e4 memset.o Since this is an import of a file from newlib, I'm not touching the formatting or correcting any checkpatch errors.

* CRIS v32: Update lib/checksum.S and lib/checksumcopy.SJesper Nilsson2008-02-08
| | | | | | - Slight tweaks, use $acr + addoq to propagate carry across the loop boundary. - Better use of latency cycles. - Remove duplicate folding of carry, it is not needed.

* CRIS v32: Add precise delay loops for ETRAX FS and ARTPEC-3.Jesper Nilsson2008-02-08
| | | | Implements cris_delay10ns.
* CRIS v32: Add new machine dependent files for Etrax-FS and Artpec-3.Jesper Nilsson2008-02-08
| | | | | | | | The two chips are somewhat different, and needs different handling. Adds handing of the dma, dram initialization, hardware settings, io, memory arbiter and pinmux Also moves the dma, dram initialization and io from CRIS v32 common files.
