From f1d205a19cc89ae5a840cd45115201847dd5b73a Mon Sep 17 00:00:00 2001 From: Jeroen Hofstee Date: Tue, 22 Jan 2013 10:44:11 +0000 Subject: [PATCH] common/lcd.c: cleanup use of global variables console_col, console_row, lcd_line_length, lcd_console_address had to be declared in board / driver specific code, but were not actually used there on many boards. Get rid of the global variables. for completeness, the ack of Bo Shen is for the atmel part Cc: Alessandro Rubini Cc: Anatolij Gustschin Cc: Bo Shen Cc: Kyungmin Park Cc: Marek Vasut Cc: Minkyu Kang Cc: Nikita Kiryanov Cc: Simon Glass Cc: Stelian Pop Cc: Tom Warren Acked-by: Bo Shen Signed-off-by: Jeroen Hofstee [agust: rebased and fixed cm_t35 board] Signed-off-by: Anatolij Gustschin --- board/cm_t35/display.c | 4 ---- board/mcc200/lcd.c | 6 ------ common/lcd.c | 6 ++++++ drivers/video/atmel_hlcdfb.c | 6 ------ drivers/video/atmel_lcdfb.c | 6 ------ drivers/video/exynos_fb.c | 6 ------ drivers/video/mpc8xx_lcd.c | 6 ------ drivers/video/pxa_lcd.c | 6 ------ drivers/video/tegra.c | 6 ------ include/lcd.h | 3 --- 10 files changed, 6 insertions(+), 49 deletions(-) diff --git a/board/cm_t35/display.c b/board/cm_t35/display.c index 885c484..d4487f3 100644 --- a/board/cm_t35/display.c +++ b/board/cm_t35/display.c @@ -381,11 +381,7 @@ static enum display_type env_parse_displaytype(char *displaytype) return NONE;
