1.FIT介绍
Flattend Image Tree
英文原版介绍:
FIT is formally a FDT, which can include images of various types (kernel, FDT blob, ramdisk, etc.) in a single blob. To boot this new uImage structure, pass the address of the blob to the "bootm" command. FIT is very flexible, supporting compression, multiple images, multiple configurations, verification through hashing and also verified boot (secure boot using RSA).
