The loop remapping the memory banks looks at reserved memory regions and then maps everything eXecute Never up to the start of the region. If the region happens to be in the same bank as the text area and it comes after it, this means the text area is temporarily mapped eXecute Never, while barebox is running from it, which results in a hang.
Fix this by remapping only after both reserved memory regions and text area have been considered.
