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>
2017-10-04treewide: replace with error() with pr_err()Masahiro Yamada1-6/+6
U-Boot widely uses error() as a bit noisier variant of printf(). This macro causes name conflict with the following line in include/linux/compiler-gcc.h: # define __compiletime_error(message) __attribute__((error(message))) This prevents us from using __compiletime_error(), and makes it difficult to fully sync BUILD_BUG macros with Linux. (Notice Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().) Let's convert error() into now treewide-available pr_err(). Done with the help of Coccinelle, excluing tools/ directory. The semantic patch I used is as follows: // <smpl> @@@@ -error +pr_err (...) // </smpl> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Reviewed-by: Simon Glass <sjg@chromium.org> [trini: Re-run Coccinelle] Signed-off-by: Tom Rini <trini@konsulko.com>
2017-05-21net: usb: mcs7830: fix non-DM ingress pathUri Mashiach1-2/+4
The mcs7830_recv() (non-DM) function discards good packets and tries to process "bad" packets due to incorrect test condition. Fix the condition and return the proper value as described in function doc. Signed-off-by: Uri Mashiach <uri.mashiach@compulab.co.il> Acked-by: Igor Grinberg <grinberg@compulab.co.il>
2016-01-12dm: net: usb: Convert mcs7830 driver to support driver modelSimon Glass1-0/+105
Adjust this driver to support driver model for Ethernet. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Joe Hershberger <joe.hershberger@ni.com>
2016-01-12dm: net: usb: Refactor mcs7830 driver ready for DM conversionSimon Glass1-121/+144
Remove stamp data and create common functions for the main Ethernet operations. This will make it easier to convert this driver to support driver model. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Joe Hershberger <joe.hershberger@ni.com>
2015-09-12Move ALLOC_CACHE_ALIGN_BUFFER() to the new memalign.h headerSimon Glass1-0/+1
Now that we have a new header file for cache-aligned allocation, we should move the stack-based allocation macro there also. Signed-off-by: Simon Glass <sjg@chromium.org>
2015-04-18net: cosmetic: Fix var naming net <-> eth driversJoe Hershberger1-1/+1
Update the naming convention used in the network stack functions and variables that Ethernet drivers use to interact with it. This cleans up the temporary hacks that were added to this interface along with the DM support. This patch has a few remaining checkpatch.pl failures that would be out of the scope of this patch to fix (drivers that are in gross violation of checkpatch.pl).

For plain array const can be either before or after the type definition. Adding both is simply redundand. Remove the later one. cc: marex@denx.de Signed-off-by: Jeroen Hofstee <jeroen@myspectrum.nl>
