pointer. This is needed for the temporary stack before
relocation.
- CONFIG_SYS_MIPS_CACHE_MODE
-
- Cache operation mode for the MIPS CPU.
- See also arch/mips/include/asm/mipsregs.h.
- Possible values are:
- CONF_CM_CACHABLE_NO_WA
- CONF_CM_CACHABLE_WA
- CONF_CM_UNCACHED
- CONF_CM_CACHABLE_NONCOHERENT
- CONF_CM_CACHABLE_CE
- CONF_CM_CACHABLE_COW
- CONF_CM_CACHABLE_CUW
- CONF_CM_CACHABLE_ACCELERATED
-
- CONFIG_SYS_XWAY_EBU_BOOTCFG
-
- Special option for Lantiq XWAY SoCs for booting from NOR flash.
- See also arch/mips/cpu/mips32/start.S.
-
CONFIG_XWAY_SWAP_BYTES
Enable compilation of tools/xway-swap-bytes needed for Lantiq
Define this to use i/o functions instead of macros
(some hardware wont work with macros)
- CONFIG_DRIVER_TI_EMAC
- Support for davinci emac
-
CONFIG_SYS_DAVINCI_EMAC_PHY_COUNT
Define this if you have more then 3 PHYs.
CONFIG_DFU_OVER_USB
This enables the USB portion of the DFU USB class
- CONFIG_DFU_MMC
- This enables support for exposing (e)MMC devices via DFU.
-
CONFIG_DFU_NAND
This enables support for exposing NAND devices via DFU.
forwarded through a router.
(Environment variable "netmask")
-- Multicast TFTP Mode:
- CONFIG_MCAST_TFTP
-
- Defines whether you want to support multicast TFTP as per
- rfc-2090; for example to work with atftp. Lets lots of targets
- tftp down the same boot image concurrently. Note: the Ethernet
- driver in use must provide a function: mcast() to join/leave a
- multicast group.
-
- BOOTP Recovery Mode:
CONFIG_BOOTP_RANDOM_DELAY
SPI configuration items (port pins to use, etc). For
an example, see include/configs/sacsng.h.
- CONFIG_HARD_SPI
-
- Enables a hardware SPI driver for general-purpose reads
- and writes. As with CONFIG_SOFT_SPI, the board configuration
- must define a list of chip-select function pointers.
- Currently supported on some MPC8xxx processors. For an
- example, see include/configs/mpc8349emds.h.
-
CONFIG_SYS_SPI_MXC_WAIT
Timeout for waiting until spi transfer completed.
default: (CONFIG_SYS_HZ/100) /* 10 ms */
200 ms.
- Configuration Management:
- CONFIG_BUILD_TARGET
-
- Some SoCs need special image types (e.g. U-Boot binary
- with a special header) as build targets. By defining
- CONFIG_BUILD_TARGET in the SoC / board header, this
- special image will be automatically built upon calling
- make / buildman.
CONFIG_IDENT_STRING
If defined, don't allow the -f switch to env set override variable
access flags.
-- CONFIG_USE_STDINT
- If stdint.h is available with your toolchain you can define this
- option to enable it. You can provide option 'USE_STDINT=1' when
- building U-Boot to enable this.
-
The following definitions that deal with the placement and management
of environment data (variable area); in general, we support the
following configurations:
a 16 bit bus.
Not all NAND drivers use this symbol.
Example of drivers that use it:
- - drivers/mtd/nand/ndfc.c
- - drivers/mtd/nand/mxc_nand.c
+ - drivers/mtd/nand/raw/ndfc.c
+ - drivers/mtd/nand/raw/mxc_nand.c
- CONFIG_SYS_NDFC_EBC0_CFG
Sets the EBC0_CFG register for the NDFC. If not defined
- CONFIG_SYS_NAND_NO_SUBPAGE_WRITE
Option to disable subpage write in NAND driver
driver that uses this:
- drivers/mtd/nand/davinci_nand.c
+ drivers/mtd/nand/raw/davinci_nand.c
