From: Karl Apsite <karl.aps...@dornerworks.com>
Added FIT_LOADABLE_PROP, so the user can identify an optional entry
named "loadables" in their .its configuration. "loadables" is a comma
separated list in the .its
example configuration:
config@1 {
description = "Xen 4.6.0-one loadable";
kernel = "xen_kernel@1";
fdt = "fdt@1";
loadables = "linux_kernel@1";
};
config@2 {
description = "Xen 4.6.0-two loadables";
kernel = "xen_kernel@1";
fdt = "fdt@1";
loadables = "linux_kernel@2", "linux_kernel@1";
};
example output:
...
Configuration 0 (config@1)
Description: Xen 4.6.0-one loadable
Kernel: xen_kernel@1
FDT: fdt@1
Loadables: linux_kernel@1
Configuration 1 (config@2)
Description: Xen 4.6.0-two loadables
Kernel: xen_kernel@1
FDT: fdt@1
Loadables: linux_kernel@2
linux_kernel@1
