Return that the volume is writable.

4ad4edfe77 cmd_ut: add a parameter prefix to the function cmd_ut_category
There is black magic in the file conftest.py that list
all the test unit. Then, all those test unit are called
in pytest. This call is done with the end of the name
(for example checksum if the full name is bloblist_test_checksum).

The result is that only test for dm are really executed.
by pytest, all others tests are listed but never executed.

This behaviour happens because the dm test unit only check
the end of the name and others tests checks the full name.

To fix this issue, I've added a prefix to the function
cmd_ut_category, and this prefix is removed when looking
for the unit test.

152781d464 spl: fit: Allow the board to tell if more images must be loaded from FIT
spl_fit_get_image_name() is used to get the names of the images that the
SPL must load from the FIT. It relies on the content of a property present
in the FIT. The list of images is thus statically defined in the FIT.
With this scheme, it quickly becomes hard to manage combinations of more
than a handful of images.
To address this problem, give the board driver code the opportunity to
add to the list of images. The images from the FIT property are loaded
first, and then the board_get_fit_loadable() is called to get more image
names.
