This causes ft_system_setup() to be called before booting
the kernel.
- CONFIG_OF_BOOT_CPU
-
- This define fills in the correct boot CPU in the boot
- param header, the default value is zero if undefined.
-
CONFIG_OF_IDE_FIXUP
U-Boot can detect if an IDE device is present or not.
default i/o. Serial console can be forced with
environment 'console=serial'.
- When CONFIG_SILENT_CONSOLE is defined, all console
- messages (by U-Boot and Linux!) can be silenced with
- 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
must be defined, to setup the maximum idle timeout for
the SMC.
-- Pre-Console Buffer:
- Prior to the console being initialised (i.e. serial UART
- initialised etc) all console output is silently discarded.
- Defining CONFIG_PRE_CONSOLE_BUFFER will cause U-Boot to
- buffer any console messages prior to the console being
- initialised to a buffer of size CONFIG_PRE_CON_BUF_SZ
- bytes located at CONFIG_PRE_CON_BUF_ADDR. The buffer is
- a circular buffer, so if more than CONFIG_PRE_CON_BUF_SZ
- bytes are output before the console is initialised, the
- earlier bytes are discarded.
-
- Note that when printing the buffer a copy is made on the
- stack so CONFIG_PRE_CON_BUF_SZ must fit on the stack.
-
- 'Sane' compilers will generate smaller code if
- CONFIG_PRE_CON_BUF_SZ is a power of 2
-
- Autoboot Command:
CONFIG_BOOTCOMMAND
Only needed when CONFIG_BOOTDELAY is enabled;
CONFIG_LAN91C96
Support for SMSC's LAN91C96 chips.
- CONFIG_LAN91C96_BASE
- Define this to hold the physical address
- of the LAN91C96's I/O space
-
CONFIG_LAN91C96_USE_32_BIT
Define this to enable 32 bit addressing
- PWM Support:
CONFIG_PWM_IMX
- Support for PWM modul on the imx6.
+ Support for PWM module on the imx6.
- TPM Support:
CONFIG_TPM
Derive USB clock from external clock "blah"
- CONFIG_SYS_USB_EXTC_CLK 0x02
- CONFIG_SYS_USB_BRG_CLK 0xBLAH
- Derive USB clock from brgclk
- - CONFIG_SYS_USB_BRG_CLK 0x04

If you have a USB-IF assigned VendorID then you may wish to
define your own vendor specific values either in BoardName.h
or directly in usbd_vendor_info.h. If you don't define
instead.
- Video support:
- CONFIG_VIDEO
-
- Define this to enable video support (for output to
- video).
-
CONFIG_VIDEO_CT69000
Enable Chips & Technologies 69000 Video chip
- CONFIG_SYS_I2C_SH_SPEED3 for for the speed channel 3
- CONFIG_SYS_I2C_SH_BASE4 for setting the register channel 4
- CONFIG_SYS_I2C_SH_SPEED4 for for the speed channel 4
- - CONFIG_SYS_I2C_SH_BASE5 for setting the register channel 5
- - CONFIG_SYS_I2C_SH_SPEED5 for for the speed channel 5
- CONFIG_SYS_I2C_SH_NUM_CONTROLLERS for number of i2c buses
- drivers/i2c/omap24xx_i2c.c
additional defines:
CONFIG_SYS_NUM_I2C_BUSES
- Hold the number of i2c buses you want to use. If you
- don't use/have i2c muxes on your i2c bus, this
- is equal to CONFIG_SYS_NUM_I2C_ADAPTERS, and you can
- omit this define.
+ Hold the number of i2c buses you want to use.
CONFIG_SYS_I2C_DIRECT_BUS
define this, if you don't use i2c muxes on your hardware.
will skip addresses 0x50 and 0x68 on a board with one I2C bus
#define CONFIG_I2C_MULTI_BUS
- #define CONFIG_SYS_I2C_MULTI_NOPROBES {{0,0x50},{0,0x68},{1,0x54}}
+ #define CONFIG_SYS_I2C_NOPROBES {{0,0x50},{0,0x68},{1,0x54}}
will skip addresses 0x50 and 0x68 on bus 0 and address 0x54 on bus 1
CONFIG_SYS_GBL_DATA_OFFSET is chosen such that the initial
data is located at the end of the available space
(sometimes written as (CONFIG_SYS_INIT_RAM_SIZE -
- CONFIG_SYS_INIT_DATA_SIZE), and the initial stack is just
+ GENERATED_GBL_DATA_SIZE), and the initial stack is just
below that area (growing from (CONFIG_SYS_INIT_RAM_ADDR +
CONFIG_SYS_GBL_DATA_OFFSET) downward.
enable SPI microcode relocation patch (MPC8xx);
define relocation offset in DPRAM [SCC4]
-- CONFIG_SYS_USE_OSCCLK:
- Use OSCM clock mode on MBX8xx board. Be careful,
- wrong setting might damage your board. Read
- doc/README.MBX before setting this variable!
-
- CONFIG_SYS_CPM_POST_WORD_ADDR: (MPC8xx, MPC8260 only)
Offset of the bootmode word in DPRAM used by post
