- the maximum receive buffer length for the SMC.
- This option is actual only for 82xx and 8xx possible.

CONFIG_WATCHDOG
If this variable is defined, it enables watchdog
support for the SoC. There must be support in the SoC
- specific code for a watchdog. For the 8xx and 8260
- CPUs, the SIU Watchdog feature is enabled in the SYPCR

CONFIG_SCSI) you must configure support for at
least one non-MTD partition type as well.

At the moment only the UHCI host controller is
- supported (PIP405, MIP405, MPC5200); define
+ supported (PIP405, MIP405); define
CONFIG_USB_UHCI to enable it.
define CONFIG_USB_KEYBOARD to enable the USB Keyboard
and define CONFIG_USB_STORAGE to enable the USB
Note:
Supported are USB Keyboards and USB Floppy drives
(TEAC FD-05PUB).
- MPC5200 USB requires additional defines:

- for USB on PSC3
- CONFIG_USB_CONFIG
- for differential drivers: 0x00001000

- Derive USB clock from external clock "blah"
- - CONFIG_SYS_USB_EXTC_CLK 0x02
-
If you have a USB-IF assigned VendorID then you may wish to

or directly in usbd_vendor_info.h. If you don't define
CONFIG_SYS_JFFS2_FIRST_BANK, CONFIG_SYS_JFFS2_NUM_BANKS
Define these for a default partition on a NOR device
-- FAT(File Allocation Table) filesystem write function support:
- CONFIG_FAT_WRITE
-
- Define this to enable support for saving memory data as a
- file in FAT formatted partition.
-
- This will also enable the command "fatwrite" enabling the
- user to write files to FAT.
-
-- FAT(File Allocation Table) filesystem cluster size:
- CONFIG_FS_FAT_MAX_CLUSTSIZE
-
- Define the max cluster size for fat operations else
- a default value of 65536 will be defined.
-
- Keyboard Support:
See Kconfig help for available keyboard drivers.
the malloc area (as defined by CONFIG_SYS_MALLOC_LEN) should
be at least 4MB.
- CONFIG_LZMA
-
- If this option is set, support for lzma compressed
- images is included.
-
- Note: The LZMA algorithm adds between 2 and 4KB of code and it
- requires an amount of dynamic memory that is given by the
- formula:
-
- (1846 + 768 << (lc + lp)) * sizeof(uint16)
-
- Where lc and lp stand for, respectively, Literal context bits
- and Literal pos bits.
-
- This value is upper-bounded by 14MB in the worst case. Anyway,
- for a ~4MB large kernel image, we have lc=3 and lp=0 for a
- total amount of (1846 + 768 << (3 + 0)) * 2 = ~41KB... that is
- a very small buffer.
-
- Use the lzmainfo tool to determinate the lc and lp values and
- then calculate the amount of needed dynamic memory (ensuring
- the appropriate CONFIG_SYS_MALLOC_LEN value).
-
CONFIG_LZO
If this option is set, support for LZO compressed images
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
- on those systems that support this (optional)
- feature, like the TQM8xxL modules.
-
- I2C Support: CONFIG_SYS_I2C
This enable the NEW i2c subsystem, and will allow you to use
eg: #define I2C_INIT (immr->im_cpm.cp_pbdir |= PB_SCL)
- I2C_PORT
-
- (Only for MPC8260 CPU). The I/O port to use (the code
- assumes both bits are on the same port). Valid values
- are 0..3 for ports A..D.
-
I2C_ACTIVE
The code necessary to make the I2C data line active
following board configurations are known to be
"pRAM-clean":

+ IVMS8, IVML24, SPD8xx,
HERMES, IP860, RPXlite, LWMON,
- FLAGADM, TQM8260

- Access to physical memory region (> 4GB)
Some basic support is provided for operations on memory not
Define this option to include a destructive SPI flash
test ('sf test').
- CONFIG_SF_DUAL_FLASH Dual flash memories
-
- Define this option to use dual flash support where two flash
- memories can be connected with a given cs line.
- Currently Xilinx Zynq qspi supports these type of connections.
-
- SystemACE Support:
CONFIG_SYSTEMACE
A better solution is to properly configure the firewall,
but sometimes that is not allowed.
-- Hashing support:
- CONFIG_CMD_HASH
-
- This enables a generic 'hash' command which can produce
- hashes / digests from a few algorithms (e.g. SHA1, SHA256).
-
- CONFIG_HASH_VERIFY
-
- Enable the hash verify command (hash -v). This adds to code
- size a little.
-
- Note: There is also a sha1sum command, which should perhaps
- be deprecated in favour of 'hash sha1'.
-
-- Freescale i.MX specific commands:
- CONFIG_CMD_HDMIDETECT
- This enables 'hdmidet' command which returns true if an
- HDMI monitor is detected. This command is i.MX 6 specific.
-
- bootcount support:
CONFIG_BOOTCOUNT_LIMIT

- CONFIG_FAT_WRITE:
- This should be defined. Otherwise it cannot save the environment file.
+ This must be enabled. Otherwise it cannot save the environment file.
- CONFIG_ENV_IS_IN_MMC:
set. If this value is set, it must be set to the same value as
CONFIG_ENV_SIZE.
-- CONFIG_SYS_SPI_INIT_OFFSET
-
- Defines offset to the initial SPI buffer area in DPRAM. The
- area is used at an early stage (ROM part) if the environment
- is configured to reside in the SPI EEPROM: We need a 520 byte
- scratch DPRAM area. It is used between the two initialization
- calls (spi_init_f() and spi_init_r()). A value of 0xB00 seems
- to be a good choice since it makes it far enough from the
- start of the data area as well as from the stack pointer.
-
Please note that the environment is read-only until the monitor
has been relocated to RAM and a RAM copy of the environment has been
created; also, when using EEPROM you will have to use getenv_f()
- CONFIG_SYS_CACHELINE_SIZE:
Cache Line Size of the CPU.
-- CONFIG_SYS_DEFAULT_IMMR:
- Default address of the IMMR after system reset.
-
- Needed on some 8260 systems (MPC8260ADS, PQ2FADS-ZU,
- and RPXsuper) to be able to adjust the position of
- the IMMR register after a reset.
-
- CONFIG_SYS_CCSRBAR_DEFAULT:
Default (power-on reset) physical address of CCSR on Freescale
PowerPC SOCs.
Virtual address of CCSR. On a 32-bit build, this is typically
the same value as CONFIG_SYS_CCSRBAR_DEFAULT.
- CONFIG_SYS_DEFAULT_IMMR must also be set to this value,
- for cross-platform code that uses that macro instead.
-
- CONFIG_SYS_CCSRBAR_PHYS:
Physical address of CCSR. CCSR can be relocated to a new
physical address, if desired. In this case, this macro should
