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: rmobile: Convert Porter to SPL Due to size limitations of the MERAM, switch U-Boot to SPL. The SPL is loaded by the SPI_LOADER into MERAM and then loads U-Boot proper into DRAM. This way U-Boot can freely grow in size in DRAM, as there is plenty of it.

ARM: rmobile: Convert to bootm_size Convert all Renesas R-Car boards to bootm_size of 256 MiB and drop both fdt_high and initrd_high. This change implies that the FDT and initrd will always be copied into the first 256 MiB of RAM instead of being used in place, which can cause various kinds of inobvious problems. The simpler problems include FDT or initrd being overwritten or being used from unaligned addresses, especially on ARM64. The overhead of copying the FDT to aligned location is negligible and these problems go away, so the benefit is significant. Regarding alignment problems with fitImage. The alignment of DT properties is always 32 bits, which implies that the alignment of the "data" property in fitImage is also 32 bits. The /incbin/ syntax plays no role here. The kernel expects all elements, including DT and initrd, to be aligned to 64 bits on ARM64, thus using them in place may not be possible. Using the bootm_size assures correct alignment, again with negligible overhead.

ARM: rmobile: Convert TPL to SPL There is currently no use for building the SPL anymore, since the SPI loader can easily be replaced by TPL and TPL does load U-Boot directly. Upgrade TPL to SPL and replace what used to be SPL with it. This way we build the U-Boot sources only twice, not thrice.

ARM: rmobile: Add TPL support on R8A7791 M2 Porter Add and enable TPL on M2 Porter. The TPL must fit into 16 kiB due to the Gen2 BootROM restriction. The TPL is running from MERAM and is capable of performing the initial initialization of PFC, Clock, GPIO, LBSC, DBSC and QSPI NOR. DBSC is responsible for bringing up the DDR DRAM access. The TPL is capable of loading the next stage, U-Boot, from either SPI NOR or UART as a fallback. If either does provide a valid U-Boot uImage, the system stops, which allows the operator to load U-Boot ie. via JTAG and start it manually.
