| A D | README.multi-dtb-fit | 3 The purpose of this feature is to enable U-Boot or the SPL to select its DTB
5 It comes in two flavors: U-Boot (CONFIG_MULTI_DTB_FIT) and SPL
9 Usually the DTB is selected by the SPL and passed down to U-Boot. But some
10 platforms don't use the SPL. In this case MULTI_DTB_FIT can used to provide
20 SPL flavor:
21 the SPL uses only a small subset of the DTB and it usually depends more
