- CONFIG_LCD_ALIGNMENT
-
- Normally the LCD is page-aligned (typically 4KB). If this is
- defined then the LCD will be aligned to this value instead.
- For ARM it is sometimes useful to use MMU_SECTION_SIZE
- here, since it is cheaper to change data cache settings on
- a per-section basis.
-
-
- CONFIG_LCD_ROTATION
-
- Sometimes, for example if the display is mounted in portrait
- mode or even if it's mounted landscape but rotated by 180degree,
- we need to rotate our content of the display relative to the
- framebuffer, so that user can read the messages which are
- printed out.
- Once CONFIG_LCD_ROTATION is defined, the lcd_console will be
- initialized with a given rotation from "vl_rot" out of
- "vidinfo_t" which is provided by the board specific code.
- The value for vl_rot is coded as following (matching to
- fbcon=rotate:<n> linux-kernel commandline):
- 0 = no rotation respectively 0 degree
- 1 = 90 degree rotation
- 2 = 180 degree rotation
- 3 = 270 degree rotation
-
- If CONFIG_LCD_ROTATION is not defined, the console will be
- initialized with 0degree rotation.
-

write commands.
-- CONFIG_SYS_FLASH_QUIET_TEST

- is useful, if some of the configured banks are only
- optionally available.
-
- CONFIG_FLASH_SHOW_PROGRESS

digits and dots. Recommended value: 45 (9..1) for 80
