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> 2018-05-06 21:58:06 +00:00			`// SPDX-License-Identifier: GPL-2.0+`
mips: add base support for QCA/Atheros ath79 SOCs This patch add some common code for QCA/Atheros ath79 SOCs such as DDR tuning, chip reset and CPU detection. Signed-off-by: Wills Wang <wills.wang@live.com> 2016-03-16 08:59:52 +00:00			`/*`

common: Move RAM-sizing functions to init.h These functions relate to memory init so move them into the init header. Signed-off-by: Simon Glass <sjg@chromium.org> 2019-12-28 17:45:05 +00:00			`#include <init.h>`
common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

board_f: Drop return value from initdram() At present we cannot use this function as an init sequence call without a wrapper, since it returns the RAM size. Adjust it to set the RAM size in global_data instead, and return 0 on success.

board_f: Rename initdram() to dram_init() This allows us to use the same DRAM init function on all archs. Add a dummy function for arc, which does not use DRAM init here.
