Summary:
========
- Board Type: Define exactly one, e.g. CONFIG_MPC8540ADS.
-- Marvell Family Member
- CONFIG_SYS_MVFS - define it if you want to enable
- multiple fs option at one time
- for marvell soc family
-
- 85xx CPU Options:
CONFIG_SYS_PPC64
as a convenience, when switching between booting from
RAM and NFS.
-- Bootcount:
- 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_AT91_HW_WDT_TIMEOUT
specify the timeout in seconds. default 2 seconds.
-- U-Boot Version:
- CONFIG_VERSION_VARIABLE
- If this variable is defined, an environment variable
- named "ver" is created by U-Boot showing the U-Boot
- version as printed by the "version" command.
- Any change to this variable will be reverted at the
- next reset.
-
- Real-Time Clock:
When CONFIG_CMD_DATE is selected, the type of the RTC
CONFIG_SUPPORT_EMMC_BOOT
Enable some additional features of the eMMC boot partitions.
- CONFIG_SUPPORT_EMMC_RPMB
- Enable the commands for reading, writing and programming the
- key for the Replay Protection Memory Block partition in eMMC.
-
- USB Device Firmware Update (DFU) class support:
CONFIG_DFU_OVER_USB
This enables the USB portion of the DFU USB class
be at least 4MB.
- MII/PHY support:
- CONFIG_PHY_ADDR
-
- The address of PHY on MII bus.
-
CONFIG_PHY_CLOCK_FREQ (ppc4xx)
The clock frequency of the MII bus
the environment like the "source" command or the
boot command first.
- CONFIG_ENV_VARS_UBOOT_RUNTIME_CONFIG
-
- Define this in order to add variables describing certain
- run-time determined information about the hardware to the
- environment. These will be named board_name, board_rev.
-
CONFIG_DELAY_ENVIRONMENT
Normally the environment is loaded when the board is
A better solution is to properly configure the firewall,
but sometimes that is not allowed.
-- bootcount support:
- CONFIG_AT91SAM9XE
- enable special bootcounter support on at91sam9xe based boards.
- CONFIG_BOOTCOUNT_RAM
- enable support for the bootcounter in RAM
- CONFIG_BOOTCOUNT_I2C
- enable support for the bootcounter on an i2c (like RTC) device.
- CONFIG_SYS_I2C_RTC_ADDR = i2c chip address
- CONFIG_SYS_BOOTCOUNT_ADDR = i2c addr which is used for
- the bootcounter.
- CONFIG_BOOTCOUNT_ALEN = address len
- CONFIG_BOOTCOUNT_EXT
- enable support for the bootcounter in EXT filesystem
- CONFIG_SYS_BOOTCOUNT_ADDR = RAM address used for read
- and write.
- CONFIG_SYS_BOOTCOUNT_EXT_INTERFACE = interface
- CONFIG_SYS_BOOTCOUNT_EXT_DEVPART = device and part
- CONFIG_SYS_BOOTCOUNT_EXT_NAME = filename
-
- Show boot progress:
CONFIG_SHOW_BOOT_PROGRESS
-150 common/cmd_nand.c Incorrect FIT image format
151 common/cmd_nand.c FIT image format OK
-- legacy image format:
- CONFIG_IMAGE_FORMAT_LEGACY
- enables the legacy image format support in U-Boot.
-
- Default:
- enabled if CONFIG_FIT_SIGNATURE is not defined.
-
- CONFIG_DISABLE_IMAGE_LEGACY
- disable the legacy image format
-
- This define is introduced, as the legacy image format is
- enabled per default for backward compatibility.
-
- Standalone program support:
CONFIG_STANDALONE_LOAD_ADDR
kernel. Needed for UBI support.
- UBI support
- CONFIG_UBI_SILENCE_MSG
-
- Make the verbose messages from UBI stop printing. This leaves
- warnings and errors enabled.
-
-
CONFIG_MTD_UBI_WL_THRESHOLD
This parameter defines the maximum difference between the highest
erase counter value and the lowest erase counter value of eraseblocks
Enable UBI fastmap debug
default: 0
-- UBIFS support
- CONFIG_UBIFS_SILENCE_MSG
-
- Make the verbose messages from UBIFS stop printing. This leaves
- warnings and errors enabled.
-
- SPL framework
CONFIG_SPL
Enable building of SPL globally.
CONFIG_SPL_NAND_DRIVERS
SPL uses normal NAND drivers, not minimal drivers.
+ CONFIG_SPL_NAND_IDENT
+ SPL uses the chip ID list to identify the NAND flash.
+ Requires CONFIG_SPL_NAND_BASE.
+
CONFIG_SPL_NAND_ECC
Include standard software ECC in the SPL
use an arch-specific makefile fragment instead, for
example if more than one image needs to be produced.
- CONFIG_FIT_SPL_PRINT
+ CONFIG_SPL_FIT_PRINT
Printing information about a FIT image adds quite a bit of
code to SPL. So this is normally disabled in SPL. Use this
option to re-enable it. This will affect the output of the
Begin and End addresses of the area used by the
simple memory test.
-- CONFIG_SYS_ALT_MEMTEST:
- Enable an alternate, more extensive memory test.
-
- CONFIG_SYS_MEMTEST_SCRATCH:
Scratch address used by the alternate memory test
You only need to set this if address zero isn't writeable
If defined, the x86 reset vector code is included. This is not
needed when U-Boot is running from Coreboot.
-- CONFIG_SPL_AM33XX_ENABLE_RTC32K_OSC:
- Enables the RTC32K OSC on AM33xx based plattforms
-
- CONFIG_SYS_NAND_NO_SUBPAGE_WRITE
Option to disable subpage write in NAND driver
driver that uses this:
projects / u-boot / blobdiff
