* env: Move env_set() to env.hSimon Glass2019-08-111-0/+1
| | | | | | | Move env_set() over to the new header file. Acked-by: Joe Hershberger <joe.hershberger@ni.com> Signed-off-by: Simon Glass <sjg@chromium.org>
* net: Fix error handling in sb_eth_raw_ofdata_to_platdata()Simon Glass2019-01-141-5/+4
| | | | | | | | At present this stores the error number in an unsigned int so an error is never detected. Use the existing signed variable instead. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Joe Hershberger <joe.hershberger@ni.com>
* sandbox: eth-raw: Make random MAC addresses available to eth-rawJoe Hershberger2018-07-261-0/+10
| | | | | | | | We don't necessarily know how many MAC addresses we'll need, so implement a ROM read so we always have something valid. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> Reviewed-by: Simon Glass <sjg@chromium.org>
* sandbox: eth-raw: Allow interface to be specified by indexJoe Hershberger2018-07-261-0/+11
| | | | | | | | With systemd stable interface names, eth0 will almost never exist. Instead of using that name in the sandbox.dts, use an index. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> Reviewed-by: Simon Glass <sjg@chromium.org>

| | | | | | | | Instead of doing a simple string compare against "lo", look for the flag that indicates a localhost interface. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> Reviewed-by: Simon Glass <sjg@chromium.org>

* SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini2018-05-071-2/+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>
* env: Rename setenv() to env_set()Simon Glass2017-08-161-2/+2
| | | | | | | | We are now using an env_ prefix for environment functions. Rename setenv() for consistency. Also add function comments in common.h. Suggested-by: Wolfgang Denk <wd@denx.de> Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: Rename dev_addr..() functionsSimon Glass2017-06-011-1/+1
| | | | | | | | | | | | | | | | | | | These support the flat device tree. We want to use the dev_read_..() prefix for functions that support both flat tree and live tree. So rename the existing functions to avoid confusion. In the end we will have: 1. dev_read_addr...() - works on devices, supports flat/live tree 2. devfdt_get_addr...() - current functions, flat tree only 3. of_get_address() etc. - new functions, live tree only All drivers will be written to use 1. That function will in turn call either 2 or 3 depending on whether the flat or live tree is in use. Note this involves changing some dead code - the imx_lpi2c.c file.

* dm: core: Replace of_offset with accessorSimon Glass2017-02-081-1/+1
| | | | | | | | | At present devices use a simple integer offset to record the device tree node associated with the device. In preparation for supporting a live device tree, which uses a node pointer instead, refactor existing code to access this field through an inline function.

* dm: eth: Avoid blocking on packet receptionSimon Glass2015-07-211-1/+1
| | | | | | | | | | | | | | | | | | | | Some devices can take a long time to work out whether they have a new packet or now. For example the ASIX USB Ethernet dongle can take 5 seconds to do this, since it waits until it gets a new packet on the wire before allowing the USB bulk read packet to be submitted. At present with driver mode the Ethernet receive code reads 32 packets. This can take a very long time if we must wait for all 32 packets. The old code (before driver model) worked by reading a single set of packets from the USB device, then processing all the packets with in. It would be nice to use the same behaviour with driver model. Add a flag to the receive method which indicates that the driver should try to find a packet if available, by consulting the hardware. When the flag is not set, it should just return any packet data it has already received. If there is none, it should return -EAGAIN so that the loop will terminate.

* net: cosmetic: Change IPaddr_t to struct in_addrJoe Hershberger2015-04-181-4/+4
| | | | | | | | | This patch is simply clean-up to make the IPv4 type that is used match what Linux uses. It also attempts to move all variables that are IP addresses use good naming instead of CamelCase. No functional change.

* sandbox: eth: Add support for using the 'lo' interfaceJoe Hershberger2015-04-181-2/+69
| | | | | | | | | | | | | | | The 'lo' interface on Linux doesn't support thinks like ARP or link-layer access like we use to talk to a normal network interface. A higher-level network API must be used to access localhost. As written, this interface is limited to not supporting ICMP since the API doesn't allow the socket to be opened for all IP traffic and be able to receive at the same time. UDP is far more useful to test with, so it was selected over ICMP. Ping won't work, but things like TFTP should work.

* sandbox: eth: Add a bridge to a real network for sandboxJoe Hershberger2015-04-181-0/+98
Implement a bridge between U-Boot's network stack and Linux's raw packet API allowing the sandbox to send and receive packets using the host machine's network interface. This raw Ethernet API requires elevated privileges. You can either run as root, or you can add the capability needed like so: sudo /sbin/setcap "CAP_NET_RAW+ep" /path/to/u-boot Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> Reviewed-by: Simon Glass <sjg@chromium.org>
