kernel configuration options. The intention is to make it easier to
build a config tool - later.
+- ARM Platform Bus Type(CCI):
+ CoreLink Cache Coherent Interconnect (CCI) is ARM BUS which
+ provides full cache coherency between two clusters of multi-core
+ CPUs and I/O coherency for devices and I/O masters
+
+ CONFIG_SYS_FSL_HAS_CCI400
+
+ Defined For SoC that has cache coherent interconnect
+ CCN-400
+
+ CONFIG_SYS_FSL_HAS_CCN504
+
+ Defined for SoC that has cache coherent interconnect CCN-504
The following options need to be configured:
supported, core will start to execute uboot when wakes up.
- Generic CPU options:
- CONFIG_SYS_GENERIC_GLOBAL_DATA
- Defines global data is initialized in generic board board_init_f().
- If this macro is defined, global data is created and cleared in
- generic board board_init_f(). Without this macro, architecture/board
- should initialize global data before calling board_init_f().
-
CONFIG_SYS_BIG_ENDIAN, CONFIG_SYS_LITTLE_ENDIAN
Defines the endianess of the CPU. Implementation of those
when no character is read on the console interface
within "Boot Delay" after reset.
- CONFIG_BOOTARGS
- This can be used to pass arguments to the bootm
- command. The value of CONFIG_BOOTARGS goes into the
- environment value "bootargs".
-
CONFIG_RAMBOOT and CONFIG_NFSBOOT
The value of these goes into the environment as
"ramboot" and "nfsboot" respectively, and can be used
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
Select one of the baudrates listed in
CONFIG_SYS_BAUDRATE_TABLE, see below.

- Monitor commands can be included or excluded
- from the build by using the #include files
- <config_cmd_all.h> and #undef'ing unwanted
- commands, or adding #define's for wanted commands.

-
- Note: Don't enable the "icache" and "dcache" commands
- (configuration option CONFIG_CMD_CACHE) unless you know
- what you (and your U-Boot users) are doing. Data
- cache cannot be enabled on systems like the
- 8xx (where accesses to the IMMR region must be
- uncached), and it cannot be disabled on all other
- systems where we (mis-) use the data cache to hold an
- initial stack and some data.
-
-
- XXX - this list needs to get updated!
-
- Removal of commands
If no commands are needed to boot, you can disable
CONFIG_CMDLINE to remove them. In this case, the command line
binary in its image. This device tree file should be in the
board directory and called <soc>-<board>.dts. The binary file
is then picked up in board_init_f() and made available through

- next reset.
-

- set and define the alt settings to expose to the host.
-
CONFIG_DFU_MMC
This enables support for exposing (e)MMC devices via DFU.
entering dfuMANIFEST state. Host waits this timeout, before
sending again an USB request to the device.
-- USB Device Android Fastboot support:
- CONFIG_USB_FUNCTION_FASTBOOT
- This enables the USB part of the fastboot gadget
-
- CONFIG_CMD_FASTBOOT

- The fastboot "flash" command requires additional information
- regarding the non-volatile storage device. Define this to
- the eMMC device that fastboot should use to store the image.

-
- CONFIG_FASTBOOT_MBR_NAME
- The fastboot "flash" command supports writing the downloaded
- image to DOS MBR.

is not available.
- CONFIG_BOOTP_DNS2 - If a DHCP client requests the DNS
- serverip from a DHCP server, it is possible that more
- than one DNS serverip is offered to the client.
- If CONFIG_BOOTP_DNS2 is enabled, the secondary DNS
- serverip will be stored in the additional environment
- variable "dnsip2". The first DNS serverip is always
- stored in the variable "dnsip", when CONFIG_BOOTP_DNS
- is defined.
-
CONFIG_BOOTP_SEND_HOSTNAME - Some DHCP servers are capable
to do a dynamic update of a DNS server. To do this, they
need the hostname of the DHCP requester.
See doc/README.link-local for more information.
+ - MAC address from environment variables
+
+ FDT_SEQ_MACADDR_FROM_ENV
+
+ Fix-up device tree with MAC addresses fetched sequentially from

currently only supports clearing the memory.
- Error Recovery:
- CONFIG_PANIC_HANG
-
- Define this variable to stop the system in case of a
- fatal error, so that you have to reset it manually.

- automatically as fast as possible, but it may be
- useful during development since you can try to debug
- the conditions that lead to the situation.

-
- When SystemACE support is added, the "ace" device type
- becomes available to the fat commands, i.e. fatls.
- TFTP Fixed UDP Port:
CONFIG_TFTP_PORT
A better solution is to properly configure the firewall,
but sometimes that is not allowed.
-- bootcount support:

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:
