2018-05-10SPDX: Convert a few files that were missed beforeTom Rini
As part of the main conversion a few files were missed. These files had additional whitespace after the '*' and before the SPDX tag and my previous regex was too strict. This time I did a grep for all SPDX tags and then filtered out anything that matched the correct styles. Fixes: 83d290c56fab ("SPDX: Convert all of our single license tags to Linux Kernel style") Reported-by: Heinrich Schuchardt <xypron.debian@gmx.de> 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>

2018-04-08net: Move enetaddr env access code to env config instead of net configAlex Kiernan
In order that we can use eth_env_* even when CONFIG_NET isn't set, move these functions to environment code from net code. This fixes failures such as: board/ti/am335x/built-in.o: In function `board_late_init': board/ti/am335x/board.c:752: undefined reference to `eth_env_set_enetaddr' u-boot/board/ti/am335x/board.c:766: undefined reference to `eth_env_set_enetaddr' which caters for use cases such as: commit f411b5cca48f ("board: am335x: Always set eth/eth1addr environment variable") when Ethernet is required in Linux, but not U-Boot.

2018-03-22net: Only access network devices after initAlexander Graf
In the efi_loader main loop we call eth_rx() occasionally. This rx function might end up calling into devices that haven't been initialized yet, potentially resulting in a lot of transfer timeouts. Instead, let's make sure the ethernet device is actually initialized before reading from or writing to it.

2018-03-22net: Fix netretry conditionLeonid Iziumtsev
The "net_try_count" counter starts from "1". And the "retrycnt" contains requested amount of retries. With current logic, that means that the actual retry amount will be one time less then what we set in "netretry" env. For example setting "netretry" to "once" will make "retrycnt" equal "1", so no retries will be triggered at all. Fix the logic by changing the statement of "if" condition.
