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: Implement riscv_get_time() API using rdtime instruction This adds an implementation of riscv_get_time() API that is using rdtime instruction. This is the case for S-mode U-Boot, and is useful for processors that support rdtime in M-mode too.

riscv: Add a SYSCON driver for SiFive's Core Local Interruptor This adds U-Boot syscon driver for SiFive's Core Local Interruptor (CLINT). The CLINT block holds memory-mapped control and status registers associated with software and timer interrupts. This driver implements the riscv_get_time() API as required by the generic RISC-V timer driver, as well as some other APIs that are needed for handling IPI.

riscv: Move do_reset() to a common place We don't have a reset method on any RISC-V board yet. Instead of adding the same 'unsupported' message for each CPU variant it might make more sense to add a generic do_reset function for all CPU variants to lib/, similar to the one for ARM (arch/arm/lib/reset.c).

riscv: implement IPI platform functions using SBI The supervisor binary interface (SBI) provides the necessary functions to implement the platform IPI functions riscv_send_ipi() and riscv_clear_ipi(). Use it to implement them. This adds support for inter-processor interrupts (IPIs) on RISC-V CPUs running in supervisor mode. Support for machine mode is already available for CPUs that include the SiFive CLINT.

riscv: add infrastructure for calling functions on other harts Harts on RISC-V boot independently, U-Boot is responsible for managing them. Functions are called on other harts with smp_call_function(), which sends inter-processor interrupts (IPIs) to all other available harts. Available harts are those marked as available in the device tree and present in the available_harts mask stored in global data. The available_harts mask is used to register all harts that have entered U-Boot. Functions are specified with their address and two function arguments (argument 2 and 3). The first function argument is always the hart ID of the hart calling the function. On the other harts, the IPI interrupt handler handle_ipi() must be called on software interrupts to handle the request and call the specified function. Functions are stored in the ipi_data data structure. Every hart has its own data structure in global data. While this is not required at the moment (all harts are expected to boot Linux), this does allow future expansion, where other harts may be used for monitoring or other tasks.
