2018-05-15riscv: Define PLATFORM__CLEAR_BIT for generic_clear_bit()Bryan O'Donoghue
riscv bitops.h provides a __clear_bit() but does not define PLATFORM__CLEAR_BIT as a result generic_clear_bit() is used instead of the architecturally provided __clear_bit(). This patch defines PLATFORM__CLEAR_BIT which means that __clear_bit() in riscv bitops.h will be called whenever generic_clear_bit() is called - as opposed to the default cross-platform generic_clear_bit().

riscv bitops.h provides a __set_bit() but does not define PLATFORM__SET_BIT as a result generic_set_bit() is used instead of the architecturally provided __set_bit(). This patch defines PLATFORM__SET_BIT which means that __set_bit() in x86 bitops.h will be called whenever generic_set_bit() is called - as opposed to the default cross-platform generic_set_bit().

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>
