At present stdio device functions do not get any clue as to which stdio device is being acted on. Some implementations go to great lengths to work around this, such as defining a whole separate set of functions for each possible device. For driver model we need to associate a stdio_dev with a device. It doesn't seem possible to continue with this work-around approach. Instead, add a stdio_dev pointer to each of the stdio member functions. Note: The serial drivers have the same problem, but it is not strictly necessary to fix that to get driver model running. Also, if we convert serial over to driver model the problem will go away. Code size increases by 244 bytes for Thumb2 and 428 for PowerPC. 22: stdio: Pass device pointer to stdio methods arm: (for 2/2 boards) all +244.0 bss -4.0 text +248.0 powerpc: (for 1/1 boards) all +428.0 text +428.0 Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Marek Vasut <marex@denx.de> Reviewed-by: Marek Vasut <marex@denx.de>

*
|
|
* Color Framebuffer Console driver for 8/15/16/24/32 bits per pixel.
|
|
*
|
|
* At the moment only the 8x16 font is tested and the font fore- and
|
|
* background color is limited to black/white/gray colors. The Linux
|
|
* logo can be placed in the upper left corner and additional board
|
|
* information strings (that normally goes to serial port) can be drawn.
|
|
*
|
|
* The console driver can use the standard PC keyboard interface (i8042)
|
|
* for character input. Character output goes to a memory mapped video
|
|
* framebuffer with little or big-endian organisation.
|
|
* With environment setting 'console=serial' the console i/o can be
|
|
* forced to serial port.
|
|
*
|
|
* The driver uses graphic specific defines/parameters/functions:
|
|
*
|
|
* (for SMI LynxE graphic chip)
|
|
*
|
|
* CONFIG_VIDEO_SMI_LYNXEM - use graphic driver for SMI 710,712,810
|
|
* VIDEO_FB_LITTLE_ENDIAN - framebuffer organisation default: big endian
|
|
* VIDEO_HW_RECTFILL - graphic driver supports hardware rectangle fill
|
|
* VIDEO_HW_BITBLT - graphic driver supports hardware bit blt
|
|
*
|
|
* Console Parameters are set by graphic drivers global struct:
|
|
*
|
|
* VIDEO_VISIBLE_COLS - x resolution
|
|
* VIDEO_VISIBLE_ROWS - y resolution
|
|
* VIDEO_PIXEL_SIZE - storage size in byte per pixel
|
|
* VIDEO_DATA_FORMAT - graphical data format GDF
|
|
* VIDEO_FB_ADRS - start of video memory
|
|
*
|
|
* CONFIG_I8042_KBD - AT Keyboard driver for i8042
|
|
* VIDEO_KBD_INIT_FCT - init function for keyboard
|
|
* VIDEO_TSTC_FCT - keyboard_tstc function
|
|
* VIDEO_GETC_FCT - keyboard_getc function
|
|
*
|
|
* CONFIG_CONSOLE_CURSOR - on/off drawing cursor is done with
|
|
* delay loop in VIDEO_TSTC_FCT (i8042)
|
|
*
|
|
* CONFIG_SYS_CONSOLE_BLINK_COUNT - value for delay loop - blink rate
|
|
* CONFIG_CONSOLE_TIME - display time/date in upper right
|
|
* corner, needs CONFIG_CMD_DATE and
|
|
* CONFIG_CONSOLE_CURSOR
|
|
* CONFIG_VIDEO_LOGO - display Linux Logo in upper left corner.
|
|
* Use CONFIG_SPLASH_SCREEN_ALIGN with
|
|
* environment variable "splashpos" to place
|
|
* the logo on other position. In this case
|
|
* no CONSOLE_EXTRA_INFO is possible.
|
|
* CONFIG_VIDEO_BMP_LOGO - use bmp_logo instead of linux_logo
|
|
* CONFIG_CONSOLE_EXTRA_INFO - display additional board information
|
|
* strings that normaly goes to serial
|
|
* port. This define requires a board
|
|
* specific function:
|
|
* video_drawstring (VIDEO_INFO_X,
|
|
* VIDEO_INFO_Y + i*VIDEO_FONT_HEIGHT,
|
|
* info);
|
|
* that fills a info buffer at i=row.
|
|
* s.a: board/eltec/bab7xx.
|
|
* CONFIG_VGA_AS_SINGLE_DEVICE - If set the framebuffer device will be
|
|
* initialized as an output only device.
|
|
* The Keyboard driver will not be
|
|
* set-up. This may be used, if you have
|
|
* no or more than one Keyboard devices
|
|
* (USB Keyboard, AT Keyboard).
|
|
*
|
|
* CONFIG_VIDEO_SW_CURSOR: - Draws a cursor after the last
|
|
* character. No blinking is provided.
|
|
* Uses the macros CURSOR_SET and
|
|
* CURSOR_OFF.
|
|
*
|
|
* CONFIG_VIDEO_HW_CURSOR: - Uses the hardware cursor capability
|
|
* of the graphic chip. Uses the macro
|
|
* CURSOR_SET. ATTENTION: If booting an
|
|
* OS, the display driver must disable
|
|
* the hardware register of the graphic
|
|
* chip. Otherwise a blinking field is
|
|
* displayed.
