2019-07-19csky: Fixup abiv1 memset errorGuo Ren1-3/+0
Current memset implementation in abiv1 is wrong and it'll cause unalign access. Just remove it and use the generic one. This patch will cause performance degradation and we will improve it with a new design in next patchset. Signed-off-by: Guo Ren <ren_guo@c-sky.com> Cc: Arnd Bergmann <arnd@arndb.de>
