[U-Boot] [PATCH 0/3] common, menu: enhancements

- add possibility to read a line with defining a timeout - add possibility to define a statusline in the menu, which is printed for every menu - show menu instead starting the u-boot shell
Heiko Schocher (3): common: add possibility for readline_into_buffer timeout common, menu: add statusline support common, menu: show menu on startup if CONFIG_MENU_SHOW is defined

Yep, fixed.

seconds, similiar to bootdelay.
of the API (add comments to the relevant funcs), and drop the CONFIG_SYS_HZ usage.
Fix this (Do it like bootdelay is done, using endticks())
Thanks for the review.

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. -mike
