[PATCH v4] FIT: Parse `load` and `entry` addresses.

[PATCH v4] FIT: Parse `load` and `entry` addresses.

[Christian Mauderer]

According to the U-Boot documentation for the FIT file format, the load
and entry have to be allways defined for a "kernel" or "standalone".
But Barebox ignored the parameters. That changes with this patch.

For backward compatibility the default address is still used for images
without `load` or `entry`.

bootm has -a and -e options to specify the load address and the entry
point. If given, these should take precedence over the addresses given
in the FIT image.

fit_open_image() has many parameters already and the two new ones are
not always needed or used. I think it's better to make getting the
addresses a separate function, fit_get_load_address() and
fit_get_entry() maybe?

Re: [PATCH v4] FIT: Parse `load` and `entry` addresses.

[Christian Mauderer]

Hello Sascha,

thanks for the review. It was a bit more effort and especially the
extra fit_get_image_address (I used one instead of separate ones for
load and entry) moved quite some code around. But I posted a v5 that
should fulfill the asked changes. The output for the four cases (load,
entry set or not set) now looks like the following:

barebox@sometarget:/mnt/mmc bootm -v -d fallback.itb
