example "env grep" and "setexpr".
- Watchdog:
- CONFIG_WATCHDOG
- If this variable is defined, it enables watchdog
- support for the SoC. There must be support in the SoC
- specific code for a watchdog. For the 8xx
- 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.
-
CONFIG_SYS_WATCHDOG_FREQ
Some platforms automatically call WATCHDOG_RESET()
from the timer interrupt handler every
CONFIG_SCSI) you must configure support for at
least one non-MTD partition type as well.
-- IDE Reset method:
- CONFIG_IDE_RESET - is this is defined, IDE Reset will
- be performed by calling the function
- ide_set_reset(int reset)
- which has to be defined in a board specific file
-
-- ATAPI Support:
- CONFIG_ATAPI
-
- Set this to enable ATAPI support.
-
- LBA48 Support
CONFIG_LBA48
When enabled, makes the IDE subsystem use 64bit sector addresses.
Default is 32bit.
-- SCSI Support:
- CONFIG_SYS_SCSI_MAX_LUN [8], CONFIG_SYS_SCSI_MAX_SCSI_ID [7] and
- CONFIG_SYS_SCSI_MAX_DEVICE [CONFIG_SYS_SCSI_MAX_SCSI_ID *
- CONFIG_SYS_SCSI_MAX_LUN] can be adjusted to define the
- maximum numbers of LUNs, SCSI ID's and target
- devices.
-
- The environment variable 'scsidevs' is set to the number of
- SCSI devices found during the last scan.
-
- NETWORK Support (PCI):
CONFIG_E1000_SPI
Utility code for direct access to the SPI bus on Intel 8257x.
sending again an USB request to the device.
- Journaling Flash filesystem support:
- CONFIG_JFFS2_NAND
- Define these for a default partition on a NAND device
-
CONFIG_SYS_JFFS2_FIRST_SECTOR,
CONFIG_SYS_JFFS2_FIRST_BANK, CONFIG_SYS_JFFS2_NUM_BANKS
Define these for a default partition on a NOR device
CONFIG_CFB_CONSOLE
CONFIG_VIDEO_SW_CURSOR
CONFIG_VGA_AS_SINGLE_DEVICE
- CONFIG_VIDEO_LOGO
CONFIG_VIDEO_BMP_LOGO
The DIU driver will look for the 'video-mode' environment
server to contact when using the "tftboot" command.
(Environment variable "serverip")
- CONFIG_KEEP_SERVERADDR
-
- Keeps the server's MAC address, in the env 'serveraddr'
- for passing to bootargs (like Linux's netconsole option)
-
- Gateway IP address:
CONFIG_GATEWAYIP
CONFIG_BOOTP_VENDOREX
CONFIG_BOOTP_MAY_FAIL
- CONFIG_BOOTP_SERVERIP - TFTP server will be the serverip
- environment variable, not the BOOTP server.
-
CONFIG_BOOTP_MAY_FAIL - If the DHCP server is not found
after the configured retry count, the call will fail
instead of starting over. This can be used to fail over
CONFIG_SPL_INIT_MINIMAL
Arch init code should be built for a very small image
- CONFIG_SYS_MMCSD_RAW_MODE_KERNEL_SECTOR
- Sector to load kernel uImage from when MMC is being
- used in raw mode (for Falcon mode)
-
CONFIG_SYS_MMCSD_RAW_MODE_ARGS_SECTOR,
CONFIG_SYS_MMCSD_RAW_MODE_ARGS_SECTORS
Sector and number of sectors to load kernel argument
Enables allocating and saving a kernel copy of the bd_info in
space between "bootm_low" and "bootm_low" + BOOTMAPSZ.
-- CONFIG_SYS_MAX_FLASH_BANKS:
- Max number of Flash memory banks
-
- CONFIG_SYS_MAX_FLASH_SECT:
Max number of sectors on a Flash chip
If this macro is defined, then CONFIG_SYS_CCSRBAR_PHYS will be
forced to a value that ensures that CCSR is not relocated.
-- 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 required.
-
- CONFIG_SYS_IMMR: Physical address of the Internal Memory.
