- description : Textual description of the component sub-image
- type : Name of component sub-image type, supported types are:
"standalone", "kernel", "ramdisk", "firmware", "script", "filesystem",
- "flat_dt".
+ "flat_dt" and others (see uimage_type in common/image.c).
- data : Path to the external file which contains this node's binary data.
- compression : Compression used by included data. Supported compressions
are "gzip" and "bzip2". If no compression is used compression property
should be set to "none".
Conditionally mandatory property:
- - os : OS name, mandatory for type="kernel", valid OS names are: "openbsd",
- "netbsd", "freebsd", "4_4bsd", "linux", "svr4", "esix", "solaris", "irix",
- "sco", "dell", "ncr", "lynxos", "vxworks", "psos", "qnx", "u_boot",

- arch : Architecture name, mandatory for types: "standalone", "kernel",
"firmware", "ramdisk" and "fdt". Valid architecture names are: "alpha",
"arm", "i386", "ia64", "mips", "mips64", "ppc", "s390", "sh", "sparc",

- entry : entry point address, address size is determined by
'#address-cells' property of the root node. Mandatory for for types:
"standalone" and "kernel".
|- kernel = "kernel sub-node unit name"
|- ramdisk = "ramdisk sub-node unit name"
|- fdt = "fdt sub-node unit-name"
+ |- loadables = "loadables sub-node unit-name"
Mandatory properties:
node of a "ramdisk" type).
- fdt : Unit name of the corresponding fdt blob (component image node of a
"fdt type").
+ - setup : Unit name of the corresponding setup binary (used for booting
+ an x86 kernel). This contains the setup.bin file built by the kernel.
+ - loadables : Unit name containing a list of additional binaries to be
+ loaded at their given locations. "loadables" is a comma-separated list
+ of strings. U-Boot will load each binary at its given start-address.
The FDT blob is required to properly boot FDT based kernel, so the minimal
configuration for 2.6 FDT kernel is (kernel, fdt) pair.
