| MULTI DTB FIT |
| |
| The purpose of this feature is to enable u-boot to select its DTB from a FIT |
| appended at the end of the binary. |
| |
| Usually the DTB is selected by the SPL and passed down to U-Boot. But some |
| platforms don't use the SPL. In this case MULTI_DTB_FIT can used to provide |
| U-Boot with a choice of DTBs. |
| The relevant DTBs are packed into a FIT (list provided by CONFIG__OF_LIST). The |
| FIT is automatically generated at the end of the compilation and appended to |
| u-boot.bin so that U-Boot can locate it and select the correct DTB from inside |
| the FIT. |
| The selection is done using board_fit_config_name_match() (same as what the SPL |
| uses to select the DTB for U-Boot). The selection happens during fdtdec_setup() |
| which is called during before relocation by board_init_f(). |
