Fix this (Do it like bootdelay is done, using endticks())

[U-Boot] [PATCH 1/3 v2] common: add possibility for readline_into_buffer timeout

[Stephan Linz]

Hello Heiko,

it seems there is a problem with this patch for some architectures. On
Microblaze I run into linker errors:

common/libcommon.o: In function `cread_line':
u-boot-bref/common/main.c:717: undefined reference to `get_ticks'
u-boot-mbref/common/main.c:717: undefined reference to `get_tbclk'
u-boot-mbref/common/main.c:720: undefined reference to `get_ticks'

AFAICS some architectures lacking these symbols. What is the default
U-Boot design line here. Should we implement the missing symbols for
Microblaze or can you introduce a CONFIG_ option to disable this new
feature?

br,
Stephan

to keep your sanity, you should implement get_{ticks,tbclk}.  look at the 
Blackfin implementation ... i think you should be able to copy & paste those 
into your own.
