CONFIG_MTD_PARTITIONS Memory Technology Device partition table.
- If IDE or SCSI support is enabled (CONFIG_CMD_IDE or
+ If IDE or SCSI support is enabled (CONFIG_IDE or
CONFIG_SCSI) you must configure support for at
least one non-MTD partition type as well.
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
If defined, then this indicates the I2C bus number for the RTC.
If not defined, then U-Boot assumes that RTC is on I2C bus 0.
- CONFIG_SYS_DTT_BUS_NUM
-
- If defined, then this indicates the I2C bus number for the DTT.
- If not defined, then U-Boot assumes that DTT is on I2C bus 0.
-
- CONFIG_SYS_I2C_DTT_ADDR:
-
- If defined, specifies the I2C address of the DTT device.
- If not defined, then U-Boot uses predefined value for
- specified DTT device.
-
CONFIG_SOFT_I2C_READ_REPEATED_START
defining this will force the i2c_read() function in
Specify the number of FPGA devices to support.
- CONFIG_CMD_FPGA_LOADMK
-
- Enable support for fpga loadmk command
-
- CONFIG_CMD_FPGA_LOADP
-
- Enable support for fpga loadp command - load partial bitstream
-
- CONFIG_CMD_FPGA_LOADBP
-
- Enable support for fpga loadbp command - load partial bitstream
- (Xilinx only)
-
CONFIG_SYS_FPGA_PROG_FEEDBACK
Enable printing of hash marks during FPGA configuration.
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
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:
