- Partition Labels (disklabels) Supported:
Zero or more of the following:
CONFIG_MAC_PARTITION Apple's MacOS partition table.
- CONFIG_DOS_PARTITION MS Dos partition table, traditional on the
- Intel architecture, USB sticks, etc.
CONFIG_ISO_PARTITION ISO partition table, used on CDROM etc.
CONFIG_EFI_PARTITION GPT partition table, common when EFI is the
bootloader. Note 2TB partition limit; see
disk/part_efi.c
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.
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
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.
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:
