Enables an 'i2c edid' command which can read EDID
information over I2C from an attached LCD display.
- Splash Screen Support: CONFIG_SPLASH_SCREEN
If this option is set, the environment is checked for
a variable "splashimage". If found, the usual display
of logo, copyright and system information on the LCD
is suppressed and the BMP image at the address
specified in "splashimage" is loaded instead. The
console is redirected to the "nulldev", too. This
allows for a "silent" boot where a splash screen is
loaded very quickly after power-on.
CONFIG_SPLASHIMAGE_GUARD
If this option is set, then U-Boot will prevent the environment
variable "splashimage" from being set to a problematic address
(see doc/README.displaying-bmps).
This option is useful for targets where, due to alignment
restrictions, an improperly aligned BMP image will cause a data
abort. If you think you will not have problems with unaligned
accesses (for example because your toolchain prevents them)
there is no need to set this option.
CONFIG_SPLASH_SCREEN_ALIGN
If this option is set the splash image can be freely positioned
on the screen. Environment variable "splashpos" specifies the
position as "x,y". If a positive number is given it is used as
number of pixel from left/top. If a negative number is given it
is used as number of pixel from right/bottom. You can also
specify 'm' for centering the image.
Example:
setenv splashpos m,m
=> image at center of screen
setenv splashpos 30,20
=> image at x = 30 and y = 20
setenv splashpos -10,m
=> vertically centered image
at x = dspWidth - bmpWidth - 9
- Gzip compressed BMP image support: CONFIG_VIDEO_BMP_GZIP
If this option is set, additionally to standard BMP
