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>

RISCV: image: Add booti support This patch adds booti support for RISC-V Linux kernel. The existing bootm method will also continue to work as it is. It depends on the following kernel patch which adds the header to the flat Image. Gzip compressed Image (Image.gz) support is not enabled with this patch. https://patchwork.kernel.org/patch/10925543/ Tested on HiFive Unleashed and QEMU.

riscv: Split SiFive CLINT support between SPL and U-Boot proper At present there is only one Kconfig option CONFIG_SIFIVE_CLINT to control the enabling of SiFive CLINT support in both SPL (M-mode) and U-Boot proper (S-mode). So for a typical SPL config that the SiFive CLINT driver is enabled in both SPL and U-Boot proper, that means the S-mode U-Boot tries to access the memory-mapped CLINT registers directly, instead of the normal 'rdtime' instruction. This was not a problem before, as the hardware does not forbid the access from S-mode. However this becomes an issue now with OpenSBI commit 8b569803475e ("lib: utils/sys: Add CLINT memregion in the root domain") that the SiFive CLINT register space is protected by PMP for M-mode access only. U-Boot proper does not boot any more with the latest OpenSBI, that access exceptions are fired forever from U-Boot when trying to read the timer value via the SiFive CLINT driver in U-Boot. To solve this, we need to split current SiFive CLINT support between SPL and U-Boot proper, using 2 separate Kconfig options.

riscv: Add basic support for SBI v0.2 The SBI v0.2 introduces a base extension which is backward compatible with v0.1. Implement all helper functions and minimum required SBI calls from v0.2 for now. All other base extension function will be added later as per need. As v0.2 calling convention is backward compatible with v0.1, remove the v0.1 helper functions and just use v0.2 calling convention. Add a new Kconfig options CONFIG_SBI for the new SBI v0.2 codes, and let CONFIG_SBI_IPI depend on it.

riscv: Provide a mechanism to fix DT for reserved memory In RISC-V, M-mode software can reserve physical memory regions by setting appropriate physical memory protection (PMP) csr. As the PMP csr are accessible only in M-mode, S-mode U-Boot can not read this configuration directly. However, M-mode software can pass this information via reserved-memory node in device tree so that S-mode software can access this information. This patch provides a framework to copy to the reserved-memory node from one DT to another. This will be used to update the DT used by U-Boot and the DT passed to the next stage OS.
