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.
