Sometimes we do not want redirect u-boot's console to screen but anyway we want write out some status information out of a u-boot script to the display. So we cannot use the normal "echo ....", instead we write explicitly using "lcdputs ..." for writing to the actual cursor position on LCD. Signed-off-by: Hannes Petermaier <oe5hpm@oevsv.at> --- Changes for v2: - better understandable commit-message - rename "puts" into "lcdputs" - move code from lcd.c to lcd_console.c --- common/lcd_console.c | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+)
