Directory Hierarchy:
port routines must be defined elsewhere
(i.e. serial_init(), serial_getc(), ...)
- CONFIG_CFB_CONSOLE
- Enables console device for a color framebuffer. Needs following
- defines (cf. smiLynxEM, i8042)
- VIDEO_FB_LITTLE_ENDIAN graphic memory organisation
- (default big endian)
- VIDEO_HW_RECTFILL graphic chip supports
- rectangle fill
- (cf. smiLynxEM)
- VIDEO_HW_BITBLT graphic chip supports
- bit-blit (cf. smiLynxEM)
- VIDEO_VISIBLE_COLS visible pixel columns
- (cols=pitch)
- VIDEO_VISIBLE_ROWS visible pixel rows
- VIDEO_PIXEL_SIZE bytes per pixel
- VIDEO_DATA_FORMAT graphic data format
- (0-5, cf. cfb_console.c)
- VIDEO_FB_ADRS framebuffer address
- VIDEO_KBD_INIT_FCT keyboard int fct
- (i.e. rx51_kp_init())
- VIDEO_TSTC_FCT test char fct
- (i.e. rx51_kp_tstc)
- VIDEO_GETC_FCT get char fct
- (i.e. rx51_kp_getc)
- CONFIG_VIDEO_LOGO display Linux logo in
- upper left corner
- CONFIG_VIDEO_BMP_LOGO use bmp_logo.h instead of
- linux_logo.h for logo.
- Requires CONFIG_VIDEO_LOGO
- CONFIG_CONSOLE_EXTRA_INFO
- additional board info beside
- the logo
- CONFIG_HIDE_LOGO_VERSION
- do not display bootloader
- version string
-
- When CONFIG_CFB_CONSOLE_ANSI is defined, console will support
- a limited number of ANSI escape sequences (cursor control,
- erase functions and limited graphics rendition control).
-
- When CONFIG_CFB_CONSOLE is defined, video console is
- default i/o. Serial console can be forced with
- environment 'console=serial'.
-
- CONFIG_SYS_CONSOLE_BG_COL: define the backgroundcolor, default
- is 0x00.
- CONFIG_SYS_CONSOLE_FG_COL: define the foregroundcolor, default
- is 0xa0.
-
- Console Baudrate:
CONFIG_BAUDRATE - in bps
Select one of the baudrates listed in
This will also enable the command "fatwrite" enabling the
user to write files to FAT.
-CBFS (Coreboot Filesystem) support
+- CBFS (Coreboot Filesystem) support:
CONFIG_CMD_CBFS
Define this to enable support for reading from a Coreboot
instead.
- Video support:
- CONFIG_VIDEO_CT69000
-
- Enable Chips & Technologies 69000 Video chip
-
- CONFIG_VIDEO_SMI_LYNXEM
- Enable Silicon Motion SMI 712/710/810 Video chip. The
- video output is selected via environment 'videoout'
- (1 = LCD and 2 = CRT). If videoout is undefined, CRT is
- assumed.
-
- For the CT69000 and SMI_LYNXEM drivers, videomode is
- selected via environment 'videomode'. Two different ways
- are possible:
- - "videomode=num" 'num' is a standard LiLo mode numbers.
- Following standard modes are supported (* is default):
-
- Colors 640x480 800x600 1024x768 1152x864 1280x1024
- -------------+---------------------------------------------
- 8 bits | 0x301* 0x303 0x305 0x161 0x307
- 15 bits | 0x310 0x313 0x316 0x162 0x319
- 16 bits | 0x311 0x314 0x317 0x163 0x31A
- 24 bits | 0x312 0x315 0x318 ? 0x31B
- -------------+---------------------------------------------
- (i.e. setenv videomode 317; saveenv; reset;)
-
- - "videomode=bootargs" all the video parameters are parsed
- from the bootargs. (See drivers/video/videomodes.c)
-
-
- CONFIG_VIDEO_SED13806
- Enable Epson SED13806 driver. This driver supports 8bpp
- and 16bpp modes defined by CONFIG_VIDEO_SED13806_8BPP
- or CONFIG_VIDEO_SED13806_16BPP
-
CONFIG_FSL_DIU_FB
Enable the Freescale DIU video driver. Reference boards for
SOCs that have a DIU should define this macro to enable DIU
here, since it is cheaper to change data cache settings on
a per-section basis.
- CONFIG_CONSOLE_SCROLL_LINES
-
- When the console need to be scrolled, this is the number of
- lines to scroll by. It defaults to 1. Increasing this makes
- the console jump but can help speed up operation when scrolling
- is slow.
CONFIG_LCD_ROTATION
- CONFIG_SYS_BAUDRATE_TABLE:
List of legal baudrate settings for this board.
-- CONFIG_SYS_CONSOLE_INFO_QUIET
- Suppress display of console information at boot.
-
-- CONFIG_SYS_CONSOLE_IS_IN_ENV
- If the board specific function
- extern int overwrite_console (void);
- returns 1, the stdin, stderr and stdout are switched to the
- serial port, else the settings in the environment are used.
-
-- CONFIG_SYS_CONSOLE_OVERWRITE_ROUTINE
- Enable the call to overwrite_console().
-
-- CONFIG_SYS_CONSOLE_ENV_OVERWRITE
- Enable overwrite of previous console environment settings.
-
- CONFIG_SYS_MEMTEST_START, CONFIG_SYS_MEMTEST_END:
Begin and End addresses of the area used by the
simple memory test.
