In addition to the previous question:

- I'm interested to calculate and store from U-boot code but the
fit_image_set_hashes is compiled only when the USE_HOSTCC symbol is
defined. Why? Is there a particular reason? I think that a lot of useful
functions (ifdef-ed by USE_HOSTCC) should be available also in u-boot
code, anyway the linker will drop the unused functions.


Any comments?

thanks
