* microblaze: Change libgcc-style functions from lib-y to obj-yDavid Holsgrove2014-07-181-11/+3
| | | | | | | | | | | | Following precedence set by MIPs: "[MIPS] Change libgcc-style functions from lib-y to obj-y" (sha1: f7c2778151f32581ea9ec567d01d5d85209fcfe6), switch the goal definition for kbuild to obj-y to ensure object files linked in vmlinux if only modules were users of these functions.

* microblaze: Fix strncpy_from_user macroMichal Simek2013-02-121-5/+4
| | | | | | | | | | | Problem happens when len in strncpy_from_user is setup and passing string has len-1 chars + \0 terminated character. In this case was returned incorrect length of the string. It should always retunrs the length of the string (not including the trailing NULL). Signed-off-by: Michal Simek <michal.simek@xilinx.com>

* microblaze: Fix ASM optimized code for LEMichal Simek2011-01-281-0/+4
| | | | | | | | | | Microblaze little-endian doesn't support ASM optimized library functions(memcpy/memmove). Kconfig doens't contain any information about endian that's why it is necessary to check it in the source code. The code is used with barrel shifter is used.

* 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>
