2018-11-20misc: Update read() and write() methods to return bytes xferedSimon Glass
At present these functions return 0 on success. For some devices we want to know how many bytes were transferred. It seems useful to adjust the API to be more like the POSIX read() and write() functions. Update these two methods, a test and all users.

2018-11-20cros_ec: Use uint instead of u8 for parametersSimon Glass
There is no advantage to using a u8 for function parameters. It forces the compiler to mask values and can increase code size. Also the command enum has been extended to 16 bits. Update the functions to use uint instead. Signed-off-by: Simon Glass <sjg@chromium.org>

2018-11-14dm: core: Respect drivers with the DM_FLAG_PRE_RELOC flag in lists_bind_fdt()Bin Meng
Currently the comments of several APIs (eg: dm_init_and_scan()) say: @pre_reloc_only: If true, bind only drivers with the DM_FLAG_PRE_RELOC flag. If false bind all drivers. The 'Pre-Relocation Support' chapter in doc/driver-model/README.txt documents the same that both device tree properties and driver flag are supported. However the implementation only checks these special device tree properties without checking the driver flag at all. This updates lists_bind_fdt() to consider both scenarios.

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>
