system clock. On most PQ3 devices this is 8, on newer QorIQ
devices it can be 16 or 32. The ratio varies from SoC to Soc.
+ CONFIG_SYS_FSL_PCIE_COMPAT
+
+ Defines the string to utilize when trying to match PCIe device
+ tree nodes for the given platform.
+
- Intel Monahans options:
CONFIG_SYS_MONAHANS_RUN_MODE_OSC_RATIO
define this to a list of base addresses for each (supported)
port. See e.g. include/configs/versatile.h
+ CONFIG_PL011_SERIAL_RLCR
+
+ Some vendor versions of PL011 serial ports (e.g. ST-Ericsson U8500)
+ have separate receive and transmit line control registers. Set
+ this variable to initialize the extra register.
+
+ CONFIG_PL011_SERIAL_FLUSH_ON_INIT
+
+ On some platforms (e.g. U8500) U-Boot is loaded by a second stage
+ boot loader that has already initialized the UART. Define this
+ variable to flush the UART at init time.
+
- Console Interface:
Depending on board, define exactly one serial port
(requires CONFIG_CMD_MEMORY)
CONFIG_CMD_SOURCE "source" command Support
CONFIG_CMD_SPI * SPI serial bus support
+ CONFIG_CMD_TFTPSRV * TFTP transfer in server mode
CONFIG_CMD_USB * USB support
CONFIG_CMD_VFD * VFD support (TRAB)
CONFIG_CMD_CDP * Cisco Discover Protocol support
- Watchdog:
CONFIG_WATCHDOG
If this variable is defined, it enables watchdog
- support. There must be support in the platform specific
- code for a watchdog. For the 8xx and 8260 CPUs, the
- SIU Watchdog feature is enabled in the SYPCR
- register.
+ support for the SoC. There must be support in the SoC
+ specific code for a watchdog. For the 8xx and 8260
+ CPUs, the SIU Watchdog feature is enabled in the SYPCR
+ register. When supported for a specific SoC is
+ available, then no further board specific code should
+ be needed to use it.
+
+ CONFIG_HW_WATCHDOG
+ When using a watchdog circuitry external to the used
+ SoC, then define this variable and provide board
+ specific code for the "hw_watchdog_reset" function.
- U-Boot Version:
CONFIG_VERSION_VARIABLE
CONFIG_VIDEO_LOGO
CONFIG_VIDEO_BMP_LOGO
- The DIU driver will look for the 'monitor' environment variable,
- and if defined, enable the DIU as a console during boot. This
- variable should be set to one of these values:
-
- '0' Output video to the DVI connector
- '1' Output video to the LVDS connector
- '2' Output video to the Dual-Link LVDS connector
+ The DIU driver will look for the 'video-mode' environment
+ variable, and if defined, enable the DIU as a console during
+ boot. See the documentation file README.video for a
+ description of this variable.
- Keyboard Support:
CONFIG_KEYBOARD
driver in use must provide a function: mcast() to join/leave a
multicast group.
- CONFIG_BOOTP_RANDOM_DELAY
- BOOTP Recovery Mode:
CONFIG_BOOTP_RANDOM_DELAY
source code. It is used to make hardware dependant
initializations.
+- CONFIG_IDE_AHB:
+ Most IDE controllers were designed to be connected with PCI
+ interface. Only few of them were designed for AHB interface.
+ When software is doing ATA command and data transfer to
+ IDE devices through IDE-AHB controller, some additional
+ registers accessing to these kind of IDE-AHB controller
+ is requierd.
+
- CONFIG_SYS_IMMR: Physical address of the Internal Memory.
