Currently, u-boot FIT image only support to load u-boot image.
To support optee-os and trusted-firmware-a, update ITS file generation
scripts, so users are able to use u-boot FIT image to load
u-boot, optee-os and treustred-firmware-a images
Add a variable "UBOOT_FIT_ARM_TRUSTED_FIRMWARE_A" to
enable trusted-firmware-a image and it is disable by default.
Add a variable "UBOOT_FIT_OPTEE_OS" to enable optee-os image
and it is disable by default.
The ITS file creation looks like as following.
1. Both optee-os and trusted-firmware-a are disabled.
'''
/dts-v1/;
/ {
images {
uboot {
};
fdt {
};
};
configurations {
default = "conf";
conf {
loadables = "uboot";
fdt = "fdt";
};
};
};
'''
2. Only enable optee-os
'''
/dts-v1/;
/ {
images {
uboot {
};
fdt {
};
optee {
};
};
configurations {
default = "conf";
conf {
firmware = "optee";
loadables = "uboot";
fdt = "fdt";
};
};
};
'''
3: Both optee-os and trusted-firmware-a are enabled
'''
/dts-v1/;
/ {
images {
uboot {
};
fdt {
};
atf {
};
optee {
};
};
configurations {
default = "conf";
conf {
firmware = "atf";
loadables = "uboot", "optee";
fdt = "fdt";
};
};
};

Hello,
This doesn't apply on top of your previous patches. Can you send a
proper series with what you want to be tested/applied?
Thanks!
