Yes I have certainly had FIT support built into SPL. However my memory
is a little unclear at this stage. I did submit quite a long list of
image-related improvements:

689a197 sandbox: image: Create a test for loading FIT images
af732a6 sandbox: image: Adjust FIT image printing to work with sandbox
4aec530 image: Use fit_image_load() to load kernel
63544a0 image: Use fit_image_load() to load FDT
48b7e7a image: Use fit_image_load() to load ramdisk
d48eed3 image: Introduce fit_image_load() to load images from FITs
2ce9f76 mkimage: Add map_sysmem() and IH_ARCH_DEFAULT to simplfy building
13d0698 image: Add device tree setup to image library
44d3a30 image: Split libfdt code into image-fdt.c
87ebee3 image: Add CONFIG_FIT_SPL_PRINT to control FIT image printing in SPL
1fe7d93 image: Remove remaining #ifdefs in image-fit.c
aa6d6db mkimage: Put FIT loading in function and tidy error handling
35e7b0f sandbox: image: Add support for booting images in sandbox
d8b7536 image: Rename hash printing to fit_image_print_verification_data()
bbb467d image: Rename fit_add_hashes() to fit_add_verification_data()
003efd7 image: Export fit_conf_get_prop_node()
e754da2 image: Move error! string to common place
ab9efc6 image: Move hash checking into its own function
b8da836 image: Rename fit_image_check_hashes() to fit_image_verify()
b726091 image: Convert fit_image_hash_set_value() to static, and rename
94e5fa4 image: Split hash node processing into its own function
604f23d image: Move HOSTCC image code to tools/
53fbb7e image: Split FIT code into new image-fit.c
61a439a image: Export fit_check_ramdisk()
859e92b image: Move timestamp #ifdefs to header file
816cb03 mkimage: Move ARRAY_SIZE to header file
0ccff50 image: Use crc header file instead of C prototypes


However I am not sure exactly what I had to do to enable FIT in SPL.
Have you tried it? What support do you think is missing? That might
help jog my memory.

Simon
