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>

ARM: dts: rmobile: Add sysinfo extras on R-Car Gen3 Add sysinfo node and phandle to the board ID EEPROM on all boards where this functionality is described in DT, which is Salvator-X(S), ULCB and Ebisu. The u-boot,dm-pre-reloc is necessary here, since the sysinfo must be available early during boot. The V3M and V3H boards currently do not describe this board ID EEPROM in upstream DT, but that could be easily added later, once the DTs contain the necessary nodes. ULCB and Ebisu needs the full EEPROM node in the u-boot extras DT, since the EEPROM node is still missing in the upstream DTs. Ebisu also needs extra compatible string override for the i2c_dvfs.

ARM: dts: rmobile: Disable RPC HF by default The RPC HF might be locked by ATF, and any access to its register space would result in complete hang. Disable the RPC HF by default. The ATF should be patched to set RPC node status = "okay" in the DT fragment it passes to U-Boot in case the RPC HF access is unlocked, and that way U-Boot could access the RPC HF safely.
