2018-12-03board: MCR3000: use new DM watchdogChristophe Leroy
This patch switches MCR3000 board to the new DM watchdog. The change in u-boot.lds is because MCR3000.o grows a bit with this patch and doesn't fit anymore below env_offset on some versions of GCC. Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr>

2018-11-26spl: Add support for passing handoff info to U-Boot properSimon Glass
There is some basic informaton that SPL normally wants to pass through to U-Boot, such as the SDRAM size and bank information. Mkae use of the new bloblist structure for this. Add a new 'handoff' blob which is set up in SPL and passed to U-Boot proper. Also adda test for sandbox_spl that checks that this works correctly and a new 'sb' command to show the information passed from SPL.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
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>
