From 46d1d5dd43e4d7c78f1fd6a5ee958d7b8a8626eb Mon Sep 17 00:00:00 2001 From: Wolfgang Denk Date: Sat, 5 Jan 2013 09:45:48 +0000 Subject: common/lcd.c: cleanup use of global variables lcd_color_fg and lcd_color_bg had to be declared in board specific code, but were not actually used there; in addition, we have getter / setter functions for these, which were not used either. Get rid of the global variables, and use the getter function where needed (so far no setter calls are needed).

This patch consolidates them into a single header file include/linux/types.h, using stdbool.h introduced in C99. All other #define, typedef and enum are removed. They are all consistent with true = 1, false = 0. Replace FALSE, False with false. Replace TRUE, True with true. Skip *.py, *.php, lib/* files.

The wait_ticks function depends on the registers r0, r6 and r7 being preserved however that is not guaranteed, e.g. if the reset function is a C function this will probably overwrite r0 and cause an endless loop. The following patch changes to using r14+r15 instead of r6+r7 (to resemble what would have been generated by a C compiler) and saves all necessary registers on the stack. The patch has been tested on a custom MPC5125 based machine using the 512x powerpc architecture.
