It is based on fixed-partitions, with some + extensions, but uses 'compatible' to indicate the contents of the node, to + avoid perturbing or confusing existing installations which use 'label' for a + particular purpose. + + Binman supports properties used as inputs to the firmware-packaging process, + such as those which control alignment of partitions. This binding addresses + these 'input' properties. For example, it is common for the 'reg' property + (an 'output' property) to be set by Binman, based on the alignment requested + in the input. + + Once processing is complete, input properties have mostly served their + purpose, at least until the firmware is repacked later, e.g. due to a + firmware update.
