[U-Boot] [PATCH V3 00/12] cleanup and refactor lcd.c

[U-Boot] [PATCH V3 00/12] cleanup and refactor lcd.c

[Nikita Kiryanov]

This series is a first step towards an end goal of merging all CONFIG_LCD
related functionality into CONFIG_VIDEO code. My plan is to start by refactoring
lcd.c into something cleaner (less ifdefs) and more modular (split code into
multiple files), then possibly refactor CONFIG_VIDEO code if needed, and then
finally: move CONFIG_LCD related functionality over to CONFIG_VIDEO code,
replacing as much CONFIG_LCD related code with CONFIG_VIDEO related code as
possible.

This specific step eliminates some unused code and refactors lcd console stuff
into its own file.

The patches ("lcd: rename console_(row|col)" to
"lcd: make lcd_drawchars() independant of lcd_base") are preparatory patches
meant to illustrate exactly what changed and where in the transition from lcd.c
to lcd_console.c, and are not necesserily code improvements when viewed out of
context.

Changes in V3:
	- Function documentation
	- Cache values of lcd_get(bg|fg)color() instead of calling the functions
	  multiple times.

The whole series was rebased over current mainline, and compile tested for arm
and powerpc.

[U-Boot] [PATCH V3 07/12] lcd: expand console api

[Nikita Kiryanov]

Introduce set_console_row(), set_console_col(), and lcd_init_console().
Use these functions in lcd functions: lcd_init(), lcd_clear(), lcd_logo().

This is a preparatory step for extracting lcd console code into its own
file.

Changes in V3:
	- Instead of invoking lcd_get(bg|fg)color() each time, do it only once
	  and cache the value. This is done in console_scrollup(),

[U-Boot] [PATCH V3 10/12] lcd: make lcd_drawchars() independant of lcd_base

[Nikita Kiryanov]

lcd_logo() has the following return value:

 #if defined(CONFIG_LCD_LOGO) && !defined(CONFIG_LCD_INFO_BELOW_LOGO)
	return (void *)((ulong)lcd_base + BMP_LOGO_HEIGHT * lcd_line_length);
 #else
	return (void *)lcd_base;
 #endif

This return value gets assigned to lcd_console_address.
lcd_console_address is not assigned or modified anywhere else.
Thus:

 #if defined(CONFIG_LCD_LOGO) && !defined(CONFIG_LCD_INFO_BELOW_LOGO):
	y' = BMP_LOGO_HEIGHT + y;
	lcd_base + y' * lcd_line_length ==
	lcd_base + (BMP_LOGO_HEIGHT + y) * lcd_line_length ==
	lcd_base + BMP_LOGO_HEIGHT * lcd_line_length + y * lcd_line_length ==
	lcd_console_address + y * lcd_line_length
 #else
	lcd_base + y * lcd_line_length == lcd_console_address + y * lcd_line_length
 #endif

This is a preparatory step for extracting lcd console code into its own
file.
