From 62facd1ff233a4734e4bc3d616ac22c5c56f926c Mon Sep 17 00:00:00 2001 From: Michael Sevakis Date: Thu, 15 Dec 2011 23:07:11 +0000 Subject: Collect some of the memory frame LCD C code. For this commit: Sansa e200v1, Gigabeat F, Gigabeat S and Mini2440 are changed over. Quite a number of other targets probably can be as well. General LCD code is moved out of the target drivers into drivers/lcd-memframe.c. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@31311 a1c6a512-1295-4272-9138-f99709370657 --- firmware/target/arm/s3c2440/lcd-s3c2440.c | 158 ++---------------------------- 1 file changed, 8 insertions(+), 150 deletions(-) (limited to 'firmware/target/arm/s3c2440/lcd-s3c2440.c') diff --git a/firmware/target/arm/s3c2440/lcd-s3c2440.c b/firmware/target/arm/s3c2440/lcd-s3c2440.c index 77be29f556..cbf4784064 100644 --- a/firmware/target/arm/s3c2440/lcd-s3c2440.c +++ b/firmware/target/arm/s3c2440/lcd-s3c2440.c @@ -19,36 +19,16 @@ * KIND, either express or implied. * ****************************************************************************/ -#include /* off_t */ - #include "config.h" #include "system.h" -#include "cpu.h" -#include "string.h" #include "lcd.h" -#include "kernel.h" #include "lcd-target.h" -#define LCDADDR(x, y) (&lcd_framebuffer[(y)][(x)]) +extern void lcd_set_active(bool active); -static bool lcd_on = true; #if defined(HAVE_LCD_ENABLE) || defined(HAVE_LCD_SLEEP) static bool lcd_powered = true; #endif -static unsigned lcd_yuv_options = 0; - -/* Copies a rectangle from one framebuffer to another.
