43 * Check if an of node should be or was bound before relocation.
44 *
45 * Devicetree nodes can be marked as needed to be bound
46 * in the loader stages via special devicetree properties.
47 *
48 * Before relocation this function can be used to check if nodes
49 * are required in either SPL or TPL stages.
50 *
51 * After relocation and jumping into the real U-Boot binary
52 * it is possible to determine if a node was bound in one of
53 * SPL/TPL stages.

55 * There are 4 settings currently in use
56 * - u-boot,dm-pre-proper: U-Boot proper pre-relocation only
e601ab1b
BM
57 * - u-boot,dm-pre-reloc: legacy and indicates any of TPL or SPL
58 * Existing platforms only use it to indicate nodes needed in
59 * SPL. Should probably be replaced by u-boot,dm-spl for
60 * existing platforms.

61 * - u-boot,dm-spl: SPL and U-Boot pre-relocation
62 * - u-boot,dm-tpl: TPL and U-Boot pre-relocation

63 * @node: of node
64 *
65 * Returns true if node is needed in SPL/TL, false otherwise.
