In this mode, a single differential clock is used to supply
clocks to the sysclock, ddrclock and usbclock.
+ CONFIG_SYS_CPC_REINIT_F
+ This CONFIG is defined when the CPC is configured as SRAM at the
+ time of U-boot entry and is required to be re-initialized.
+
+ CONFIG_DEEP_SLEEP
+ Inidcates this SoC supports deep sleep feature. If deep sleep is
+ supported, core will start to execute uboot when wakes up.
+
- Generic CPU options:
CONFIG_SYS_BIG_ENDIAN, CONFIG_SYS_LITTLE_ENDIAN
CONFIG_SYS_FSL_DDRC_GEN3
Freescale DDR3 controller.
+ CONFIG_SYS_FSL_DDRC_GEN4
+ Freescale DDR4 controller.
+
CONFIG_SYS_FSL_DDRC_ARM_GEN3
Freescale DDR3 controller for ARM-based SoCs.
CONFIG_SYS_FSL_DDR3
Board config to use DDR3. It can be enabled for SoCs with
- Freescale DDR3 controllers.
+ Freescale DDR3 or DDR3L controllers.
+
+ CONFIG_SYS_FSL_DDR3L
+ Board config to use DDR3L. It can be enabled for SoCs with
+ DDR3L controllers.
+
+ CONFIG_SYS_FSL_DDR4
+ Board config to use DDR4. It can be enabled for SoCs with
+ DDR4 controllers.
CONFIG_SYS_FSL_IFC_BE
Defines the IFC controller register space as Big Endian
PBI commands can be used to configure SoC before it starts the execution.
Please refer doc/README.pblimage for more details
+ CONFIG_SPL_FSL_PBL
+ It adds a target to create boot binary having SPL binary in PBI format
+ concatenated with u-boot binary.
+
CONFIG_SYS_FSL_DDR_BE
Defines the DDR controller register space as Big Endian

If set, the workarounds for these ARM errata are applied early
during U-Boot startup. Note that these options force the
The default command configuration includes all commands
except those marked below with a "*".
+ CONFIG_CMD_AES AES 128 CBC encrypt/decrypt
CONFIG_CMD_ASKENV * ask for env variable
CONFIG_CMD_BDI bdinfo
CONFIG_CMD_BEDBUG * Include BedBug Debugger
CONFIG_CMD_CDP * Cisco Discover Protocol support
CONFIG_CMD_MFSL * Microblaze FSL support
CONFIG_CMD_XIMG Load part of Multi Image
-
+ CONFIG_CMD_UUID * Generate random UUID or GUID string
EXAMPLE: If you want all functions except of network
support you can write:
for your device
- CONFIG_USBD_PRODUCTID 0xFFFF
- Some USB device drivers may need to check USB cable attachment.
- In this case you can enable following config in BoardName.h:
- CONFIG_USB_CABLE_CHECK
- This enables function definition:
- - usb_cable_connected() in include/usb.h
- Implementation of this function is board-specific.
-
- ULPI Layer Support:
The ULPI (UTMI Low Pin (count) Interface) PHYs are supported via
the generic ULPI layer. The generic layer accesses the ULPI PHY
this to the maximum filesize (in bytes) for the buffer.
Default is 4 MiB if undefined.
+ DFU_DEFAULT_POLL_TIMEOUT
+ Poll timeout [ms], is the timeout a device can send to the
+ host. The host must wait for this timeout before sending
+ a subsequent DFU_GET_STATUS request to the device.
+
+ DFU_MANIFEST_POLL_TIMEOUT
+ Poll timeout [ms], which the device sends to the host when
+ entering dfuMANIFEST state. Host waits this timeout, before
+ sending again an USB request to the device.
+
+- USB Device Android Fastboot support:
+ CONFIG_CMD_FASTBOOT
+ This enables the command "fastboot" which enables the Android
+ fastboot mode for the platform's USB device. Fastboot is a USB
+ protocol for downloading images, flashing and device control
+ used on Android devices.
+ See doc/README.android-fastboot for more information.
+
+ CONFIG_ANDROID_BOOT_IMAGE
+ This enables support for booting images which use the Android
+ image format header.
+
+ CONFIG_USB_FASTBOOT_BUF_ADDR
+ The fastboot protocol requires a large memory buffer for
+ downloads. Define this to the starting RAM address to use for
+ downloaded images.
+
+ CONFIG_USB_FASTBOOT_BUF_SIZE
+ The fastboot protocol requires a large memory buffer for
+ downloads. This buffer should be as large as possible for a
+ platform. Define this to the size available RAM for fastboot.
+
- Journaling Flash filesystem support:
CONFIG_JFFS2_NAND, CONFIG_JFFS2_NAND_OFF, CONFIG_JFFS2_NAND_SIZE,
CONFIG_JFFS2_NAND_DEV
continuing (the hardware starts execution after just
loading the first page rather than the full 4K).
+ CONFIG_SPL_SKIP_RELOCATE
+ Avoid SPL relocation
+
CONFIG_SPL_NAND_BASE
Include nand_base.c in the SPL. Requires
CONFIG_SPL_NAND_DRIVERS.
are used to identify the storage device (NOR flash, SPI, etc) and the address
within that device.
-- CONFIG_SYS_QE_FMAN_FW_ADDR
- The address in the storage device where the firmware is located. The
+- CONFIG_SYS_FMAN_FW_ADDR
+ The address in the storage device where the FMAN microcode is located. The
+ meaning of this address depends on which CONFIG_SYS_QE_FW_IN_xxx macro
+ is also specified.
+
+- CONFIG_SYS_QE_FW_ADDR
+ The address in the storage device where the QE microcode is located. The
meaning of this address depends on which CONFIG_SYS_QE_FW_IN_xxx macro
is also specified.
