2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini1-2/+1
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>
2018-01-28tools: include necessary headers explicitlyMasahiro Yamada1-0/+1
Several host-tools use "bool" type without including <stdbool.h>. This relies on the crappy header inclusion chain. tools/Makefile has the following line: HOST_EXTRACFLAGS += -include $(srctree)/include/libfdt_env.h \ All host-tools are forced to include libfdt_env.h even if they are totally unrelated to FDT. Then, <stdbool.h> is indirectly included as follows: include/libfdt_env.h -> include/linux/types.h -> <stdbool.h> I am fixing this horrible crap. In advance, I need to add necessary include directives explicitly. tools/fdtgrep.c needs more; <fctl.h> for open() and <errno.h> for errno.

2017-02-07tools: Add tool to add crc8 to a mac addressoliver@schinagl.nl1-0/+75
This patch adds a little tool that takes a generic MAC address and generates a CRC byte for it. The output is the full MAC address without any separators, ready written into an EEPROM.
