Vincent Jardin <vjardin@free.fr> says: 3 commits providing documentation of impacts and testing the dispatch for null_dev_desc_ok fstypes (semihosting, ubifs, sandbox) in the generic `load <iface> ...` command. The test does not cover ubifs, I could not make it work with qemu. Since the code logic is there and testing with semihost is done, it should cover the needed cases.
