the "silent" environment variable. See
doc/README.silent for more information.
+ 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
as a convenience, when switching between booting from
RAM and NFS.
+- Bootcount:
+ CONFIG_BOOTCOUNT_LIMIT
+ Implements a mechanism for detecting a repeating reboot
+ cycle, see:
+ http://www.denx.de/wiki/view/DULG/UBootBootCountLimit
+
+ CONFIG_BOOTCOUNT_ENV
+ If no softreset save registers are found on the hardware
+ "bootcount" is stored in the environment. To prevent a
+ saveenv on all reboots, the environment variable
+ "upgrade_available" is used. If "upgrade_available" is
+ 0, "bootcount" is always 0, if "upgrade_available" is
+ 1 "bootcount" is incremented in the environment.
+ So the Userspace Applikation must set the "upgrade_available"
+ and "bootcount" variable to 0, if a boot was successfully.

- Pre-Boot Commands:
CONFIG_PREBOOT
CONFIG_CMD_ELF * bootelf, bootvx
CONFIG_CMD_ENV_CALLBACK * display details about env callbacks
CONFIG_CMD_ENV_FLAGS * display details about env flags
+ CONFIG_CMD_ENV_EXISTS * check existence of env variable
CONFIG_CMD_EXPORTENV * export the environment
CONFIG_CMD_EXT2 * ext2 command support
CONFIG_CMD_EXT4 * ext4 command support
- GPIO Support:
CONFIG_PCA953X - use NXP's PCA953X series I2C GPIO
- CONFIG_PCA953X_INFO - enable pca953x info command
The CONFIG_SYS_I2C_PCA953X_WIDTH option specifies a list of
chip-ngpio pairs that tell the PCA953X driver the number of
for your device
- CONFIG_USBD_PRODUCTID 0xFFFF
+ Some USB device drivers may need to check USB cable attachment.
+ In this case you can enable following config in BoardName.h:
+ CONFIG_USB_CABLE_CHECK
+ This enables function definition:
+ - usb_cable_connected() in include/usb.h
+ Implementation of this function is board-specific.
+
- ULPI Layer Support:
The ULPI (UTMI Low Pin (count) Interface) PHYs are supported via
the generic ULPI layer. The generic layer accesses the ULPI PHY
NOTE : currently only supported on AM335x platforms.
+- CONFIG_SPL_AM33XX_ENABLE_RTC32K_OSC:
+ Enables the RTC32K OSC on AM33xx based plattforms
+
