CONFIG_SYS_FSL_DSP_CCSRBAR_DEFAULT
This value denotes start offset of DSP CCSR space.
- CONFIG_SYS_FSL_DDR_EMU
- Specify emulator support for DDR. Some DDR features such as
- deskew training are not available.
-
- Generic CPU options:
CONFIG_SYS_BIG_ENDIAN, CONFIG_SYS_LITTLE_ENDIAN
Defines the endianess of the CPU. Implementation of those
values is arch specific.
+ CONFIG_SYS_FSL_DDR
+ Freescale DDR driver in use. This type of DDR controller is
+ found in mpc83xx, mpc85xx, mpc86xx as well as some ARM core
+ SoCs.
+
+ CONFIG_SYS_FSL_DDR_ADDR
+ Freescale DDR memory-mapped register base.
+
+ CONFIG_SYS_FSL_DDR_EMU
+ Specify emulator support for DDR. Some DDR features such as
+ deskew training are not available.
+
+ CONFIG_SYS_FSL_DDRC_GEN1
+ Freescale DDR1 controller.
+
+ CONFIG_SYS_FSL_DDRC_GEN2
+ Freescale DDR2 controller.
+
+ CONFIG_SYS_FSL_DDRC_GEN3
+ Freescale DDR3 controller.
+
+ CONFIG_SYS_FSL_DDRC_ARM_GEN3
+ Freescale DDR3 controller for ARM-based SoCs.
+
+ CONFIG_SYS_FSL_DDR1
+ Board config to use DDR1. It can be enabled for SoCs with
+ Freescale DDR1 or DDR2 controllers, depending on the board
+ implemetation.
+
+ CONFIG_SYS_FSL_DDR2
+ Board config to use DDR2. It can be eanbeld for SoCs with
+ Freescale DDR2 or DDR3 controllers, depending on the board
+ implementation.
+
+ CONFIG_SYS_FSL_DDR3
+ Board config to use DDR3. It can be enabled for SoCs with
+ Freescale DDR3 controllers.
+
- Intel Monahans options:
CONFIG_SYS_MONAHANS_RUN_MODE_OSC_RATIO
as a convenience, when switching between booting from
RAM and NFS.
+- Bootcount:
+ CONFIG_BOOTCOUNT_LIMIT
+ Implements a mechanism for detecting a repeating reboot
+ cycle, see:
+ http://www.denx.de/wiki/view/DULG/UBootBootCountLimit
+
+ 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
kernel). Defining CONFIG_STATUS_LED enables this
feature in U-Boot.
+ Additional options:
+
+ CONFIG_GPIO_LED
+ The status LED can be connected to a GPIO pin.
+ In such cases, the gpio_led driver can be used as a
+ status LED backend implementation. Define CONFIG_GPIO_LED
+ to include the gpio_led driver in the U-Boot binary.
+
+ CONFIG_GPIO_LED_INVERTED_TABLE
+ Some GPIO connected LEDs may have inverted polarity in which
+ case the GPIO high value corresponds to LED off state and
+ GPIO low value corresponds to LED on state.
+ In such cases CONFIG_GPIO_LED_INVERTED_TABLE may be defined
+ with a list of GPIO LEDs that have inverted polarity.
+
- CAN Support: CONFIG_CAN_DRIVER
Defining CONFIG_CAN_DRIVER enables CAN driver support
- CONFIG_SYS_OMAP24_I2C_SPEED4 speed channel 4
- CONFIG_SYS_OMAP24_I2C_SLAVE4 slave addr channel 4
+ - drivers/i2c/zynq_i2c.c
+ - activate this driver with CONFIG_SYS_I2C_ZYNQ
+ - set CONFIG_SYS_I2C_ZYNQ_SPEED for speed setting
+ - set CONFIG_SYS_I2C_ZYNQ_SLAVE for slave addr
+
+ - drivers/i2c/s3c24x0_i2c.c:
+ - activate this driver with CONFIG_SYS_I2C_S3C24X0
+ - This driver adds i2c buses (11 for Exynos5250, Exynos5420
+ 9 i2c buses for Exynos4 and 1 for S3C24X0 SoCs from Samsung)
+ with a fix speed from 100000 and the slave addr 0!
+
additional defines:
CONFIG_SYS_NUM_I2C_BUSES
CONFIG_SPL_MPC8XXX_INIT_DDR_SUPPORT
Set for the SPL on PPC mpc8xxx targets, support for
- arch/powerpc/cpu/mpc8xxx/ddr/libddr.o in SPL binary.
+ drivers/ddr/fsl/libddr.o in SPL binary.
CONFIG_SPL_COMMON_INIT_DDR
Set for common ddr init with serial presence detect in
NOTE : currently only supported on AM335x platforms.
+- CONFIG_SPL_AM33XX_ENABLE_RTC32K_OSC:
+ Enables the RTC32K OSC on AM33xx based plattforms
+
Freescale QE/FMAN Firmware Support:
