This patch adds a function for finding a node in flat tree based on an alias name. It can be used in early boot code.Typical use case is a situation when early code needs data from a arbitrary tree node, eg. base address of "serial0" to initialise debug output or some sort of ID register to probe hardware. The tree source could look like that: / { aliases { serial0 =&uart0; }; uart0: uart@f0001000 { reg =<0xf0001000 0x1000>; }; } Signed-off-by: Pawel Moll<pawel.m...@arm.com>
