after commit "common: add possibility for readline_into_buffer timeout" (sha1:9c34831) was applied. The Microblaze generic build fails with error below: common/libcommon.o: In function `cread_line': /devel/u-boot/common/main.c:717: undefined reference to `get_ticks' /devel/u-boot/common/main.c:717: undefined reference to `get_tbclk' /devel/u-boot/common/main.c:720: undefined reference to `get_ticks' Signed-off-by: Stephan Linz <linz@li-pro.net> Acked-by: Michal Simek <monstr@monstr.eu>
