g) Flash chip nodes

Flash chips (Memory Technology Devices) are often used for solid state
file systems on embedded devices.

Required properties:

- device_type : has to be "rom"
- compatible : Should specify what this ROM device is compatible with
(i.e. "onenand"). Currently, this is most likely to be "direct-mapped"
(which corresponds to the MTD physmap mapping driver).
- regs : Offset and length of the register set (or memory mapping) for
the device.

Recommended properties :

- bank-width : Width of the flash data bus in bytes. Required
for the NOR flashes (compatible == "direct-mapped" and others) ONLY.
- partitions : Several pairs of 32-bit values where the first value is
partition's offset from the start of the device and the second one is
partition size in bytes with LSB used to signify a read only
partititon (so, the parition size should always be an even number).
- partition-names : The list of concatenated zero terminated strings
representing the partition names.

Example:

flash@ff000000 {
device_type = "rom";
compatible = "direct-mapped";
regs = <ff000000 01000000>;
bank-width = <4>;
partitions = <00000000 00f80000
00f80000 00080001>;
partition-names = "fs\0firmware";
};

More devices will be defined as this spec matures.
