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>

The DDR3-SDRAM initialization sequence is implemented in accordance with the DDR3-SRAM/DDR3L-SDRAM initialization section described in the SAMA5D2 datasheet. Add registers and definitions of mpddrc controller, which is used to support DDR3 devices.

Add struct atmel_mpddrc_config to accommodate the mpddrc register configurations, not using the mpddrc register map structure, struct atmel_mpddrc, in order to increase readability and reduce run-time memory use.

2015-08-21arm: at91: mpddr: allow multiple DDR controllersErik van Luijk
The mpddr.c depends on ATMEL_BASE_MPDDRC for the base address to configure the controller. This cannot be used when there is more than one controller (i.e. AT91SAM9G45, AT91SAM9M10).
