[U-Boot] [PATCH V2 0/4] common/lcd cleanup

[Nikita Kiryanov]

This patch series attempts to simplify #ifdef complexity in common/lcd.c.

It was compile tested on Arm and PowerPC using MAKEALL

checkpatch reports warnings on some of the patches:
0003: WARNING: use of volatile is usually wrong
	Since 'volatile' was in the original code I left it in the patch as
	well.

Changes in V2:
	- Rebased on u-boot-video
	- patches 2 and 3 of original patchset dropped because I'm not sure
	what to do about them
	- simplify lcd_logo: used bitmap_display() to further simplify code
	- simplify lcd_display_bitmap: fixed pointer increment error
	- simplify lcd_display_bitmap: change to simplify lcd_logo breaks
	MCC200 board because it does not #define CONFIG_CMD_BMP. Added a local
	implementation of bitmap_display().

Nikita Kiryanov (4):
  common lcd: simplify lcd_logo
  common lcd: simplify lcd_display
  common lcd: simplify core functions
  common lcd: simplify lcd_display_bitmap
