SPDX: Convert all of our single license tags to Linux Kernel style When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

menu: add support for client defined statusline function Currently displaying status line is done in a weak function menu_display_statusline(). bootmenu.c overrides the weak default function. It calls menu_default_choice() and interprets the data as struct bootmenu_entry. pxe boot also uses common menu code for pxe menus. If there is a system that enables both bootmenu and pxe, menu_display_statusline() defined in bootmenu.c will be called and it will interpret struct pxe_label as struct bootmenu_entry. This leads to data aborts and pxe menu corruptions. This patch adds support for client defined statusline function to resolve the above bug.
