2012-03-29	fdt: Add fdtdec_find_aliases() to deal with alias nodes	Simon Glass
	Stephen Warren pointed out that we should use nodes whether or not they have an alias in the /aliases section. The aliases section specifies the order so far as it can, but is not essential. Operating without alisses is useful when the enumerated order of nodes does not matter (admittedly rare in U-Boot). This is considerably more complex, and it is important to keep this complexity out of driver code. This patch creates a function fdtdec_find_aliases() which returns an ordered list of node offsets for a particular compatible ID, taking account of alias nodes.

2011-10-26	fdt: add decode helper library	Simon Glass
	This library provides useful functions to drivers which want to use the fdt to control their operation. Functions are provided to: - look up and enumerate a device type (for example assigning i2c bus 0, i2c bus 1, etc.) - decode basic types from the fdt, like addresses and integers While this library is not strictly necessary, it helps to minimise the changes to a driver, in order to make it work under fdt control. Less code is required, and so the barrier to switch drivers over is lower. Additional functions to read arrays and GPIOs could be made available here also.
