====
|

|
|
|

|
|
Example FIT image description file demonstrating the usage of the
|
||
|
|
bootm command to launch UEFI binaries.
|
||
|
|
|
||
|
|
Two boot configurations are available to enable booting GRUB2 on QEMU,
|
||
|
|
the former uses a FDT blob contained in the FIT image, while the later
|
||
|
|
relies on the FDT provided by the board emulator.
