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>

x86: Refactor the zboot innards so they can be reused with a vboot image If vboot successfully verifies a kernel, it will leave it in place and basically ready to boot. The zeropage table which is part of the x86 boot protocol is at the end of the kernel, though, instead of the beginning, and because the image is already in place there's no need to copy it around. This change refactors the code which implements the zboot command so that the configuration of the zeropage table and loading the pieces of the kernel into memory are done separately. Also, because the command line goes before the zeropage table in vboot which is somewhat incompatible with the normal protocol, where to put the command line is a now a parameter instead of being hard coded.

x86: Add support for booting Linux using the 32 bit boot protocol This change conditionally modifies the zboot command so that it can use the 32 bit boot protocol. This is necessary because the 16 bit realmode entry point assumes that it can call BIOS services which neither coreboot nor u-boot provide. Signed-off-by: Gabe Black <gabeblack@chromium.org>
