lcd: make lcd_drawchars() independant of lcd_base
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.
