2018-11-26riscv: do not reimplement generic io functionsLukas Auer
RISC-V U-Boot reimplements the generic io functions from asm-generic/io.h. Remove the redundant implementation and include the generic io.h instead. Signed-off-by: Lukas Auer <lukas.auer@aisec.fraunhofer.de> Reviewed-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Rick Chen <rick@andestech.com>
2018-11-26riscv: make use of the barrier functions from LinuxLukas Auer
Replace the barrier functions in arch/riscv/include/asm/io.h with those defined in barrier.h, which is imported from Linux. This version is modified to remove the include statement of asm-generic/barrier.h, which is not available in U-Boot or required.

2018-11-26riscv: fix use of incorrectly sized variablesLukas Auer
The RISC-V arch incorrectly uses 32-bit instead of 64-bit variables in several places. Fix this. In addition, BITS_PER_LONG is set to 64 on RV64I systems. Signed-off-by: Lukas Auer <lukas.auer@aisec.fraunhofer.de> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
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>
