* SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini2018-05-0713-26/+13
| | | | | | | | | | | | | | | | | | | | 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 patch is also backward compatible with old revision EVM and EVM with WireBond SoC. Their ARM/DDR3 run at 600MHz/800 MT/s. The new SoC supports 2 different speeds at 1GHz and 600MHz. Modyfied the CPU Name to show which SoC is used in the EVM. Modified the DDR3 configuration to reflect New SoC supports 2 different CPU and DDR3 speeds, 1GHz/1066MT and 600MHz/800MT. Added new inline function board_it_k2g_g1() for the new FlipChip 1GHz, and set the u-boot env variable board_name accordingly.

| | | | | | | | | | | | | | | | For K2G, runtime DTB selection utilizes the embedded_dtb_select function. Therefore, define the function which will perform a EEPROM read and then retries selecting the correct dtb now that it can detect which board its on. For other Keystone devices use an empty function since they will still use the embedded FIT functionality but their FIT will only contain a single dtb. Most production K2G boards do not have their EEPROM programmed. Therefore, perform a test to verify a K2G GP is currently being used and if it is then set the values normally set by a EEPROM read.
