| 2 | |
| 3 | The purpose of this feature is to enable u-boot to select its DTB from a FIT |
| 4 | appended at the end of the binary. |
| 5 | |
| 6 | Usually the DTB is selected by the SPL and passed down to U-Boot. But some |
| 7 | platforms don't use the SPL. In this case MULTI_DTB_FIT can used to provide |
| 8 | U-Boot with a choice of DTBs. |
| 9 | The relevant DTBs are packed into a FIT (list provided by CONFIG__OF_LIST). The |
| 10 | FIT is automatically generated at the end of the compilation and appended to |
| 11 | u-boot.bin so that U-Boot can locate it and select the correct DTB from inside |
| 12 | the FIT. |
| 13 | The selection is done using board_fit_config_name_match() (same as what the SPL |
| 14 | uses to select the DTB for U-Boot). The selection happens during fdtdec_setup() |
| 15 | which is called during before relocation by board_init_f(). |
