2018-05-07git-mailrc: Update some addresses and aliasesTom Rini
- Based on commit 08ae21af9671 ("MAINTAINERS: Switch nxp.com domain") update or drop some formerly Freescale addresses. - Update a few aliases to reflect current custodians Signed-off-by: Tom Rini <trini@konsulko.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>

2018-04-27clang: Update documentationTom Rini
As of clang-5.0, things have changed a bit. First, we cannot automatically guess -target values as if we do not pass one with CC then cc-option will fail. Second, to disable movt/movw relocations the argument has become -mno-movt. Related to the target part, we cannot use arm-none-eabi as that ends up being too generic of an ARM target for things like say rpi_3_32b to work. Signed-off-by: Tom Rini <trini@konsulko.com>

address At present two environment variables 'e820data'/'e820info' are required to boot a VxWorks x86 kernel, but this is superfluous. The offset of these two tables are actually at a fixed offset from the kernel memory base address and we can provide the kernel memory base address to U-Boot via only one variable 'vx_phys_mem_base'.

2018-02-03log: Add a way to log error-return valuesSimon Glass
When functions return an error it propagates up the stack to the point where it is reported. Often the error code provides enough information about the root cause of the error that this is obvious what went wrong. However in some cases the error may be hard to trace. For example if a driver uses several devices to perform an operation, it may not be obvious which one failed. Add a log_ret() macro to help with this. This can be used to wrap any error-return value. The logging system will then output a log record when the original error is generated, making it easy to trace the call stack of the error. This macro can significantly impact code size, so its use is controlled by a Kconfig option, which is enabled for sandbox. Signed-off-by: Simon Glass <sjg@chromium.org>
