2024-05-19Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""Tom Rini
When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"' I failed to notice that b4 noticed it was based on next and so took that as the base commit and merged that part of next to master. This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

If we sent a DHCP packet and get a BOOTP response from the server, we shouldn't try to send a DHCPREQUEST packet, since it won't be DHCPACKed. Transition straight to BIND. This is only enabled for UNIT_TEST to avoid bloat, since I suspect the number of BOOTP servers in the wild is vanishingly small.

At this point, the remaining places where we have a symbol that is defined as CONFIG_... are in fairly odd locations. While as much dead code has been removed as possible, some of these locations are simply less obvious at first. In other cases, this code is used, but was defined in such a way as to have been missed by earlier checks. Perform a rename of all such remaining symbols to be CFG_... rather than CONFIG_...

2020-12-01Adds basic support for ProxyDHCPLyle Franklin
- ProxyDHCP allows a second DHCP server to exist alongside your main DHCP server and supply additional BOOTP related options - When u-boot sends out a DHCP request, the real DHCP server will respond with a normal response containing the new client IP address while simultaneously the ProxyDHCP server will respond with a blank client IP address and a `bootfile` option - This patch adds CONFIG_SERVERIP_FROM_PROXYDHCP (default false) to enable this behavior and CONFIG_SERVERIP_FROM_PROXYDHCP_DELAY_MS (default 100) which tells u-boot to wait additional time after receiving the main DHCP response to give the ProxyDHCP response time to arrive - The PXE spec for ProxyDHCP is more complicated than the solution added here as diagramed on page 16: http://www.pix.net/software/pxeboot/archive/pxespec.pdf: ``` DHCP Discover will be retried four times. The four timeouts are 4, 8, 16 and 32 seconds respectively. If a DHCPOFFER is received without an Option timeouts in an attempt to receive a PXE response. ``` - Adding a simple delay worked for my purposes but let me know if a more robust solution is required Signed-off-by: Lyle Franklin <lylejfranklin@gmail.com>

2018-07-02net: Add option to prefer bootp/dhcp serveripAlexander Graf
Currently we can choose between 2 different types of behavior for the serverip variable: 1) Always overwrite it with the DHCP server IP address (default) 2) Ignore what the DHCP server says (CONFIG_BOOTP_SERVERIP) This patch adds a 3rd option: 3) Use serverip from DHCP if no serverip is given (CONFIG_BOOTP_PREFER_SERVERIP) With this new option, we can have the default case that a boot file gets loaded from the DHCP provided TFTP server work while allowing users to specify their own serverip variable to explicitly use a different tftp server.

2018-07-02net: Prefer command line argumentsAlexander Graf
We can call commands like dhcp and bootp without arguments or with explicit command line arguments that really should tell the code where to look for files instead. Unfortunately, the current code simply overwrites command line arguments in the dhcp case with dhcp values. This patch allows the code to preserve the command line values if they were set on the command line. That way the semantics are slightly more intuitive. The reason this patch does that by introducing a new variable is that we can not rely on net_boot_file_name[0] being unset, as today it's completely legal to call "dhcp" and afterwards run "tftp" and expect the latter to repeat the same query as before. I would prefer not to break that behavior in case anyone relies on it. Signed-off-by: Alexander Graf <agraf@suse.de> Acked-by: Joe Hershberger <joe.hershberger@ni.com>

2016-05-27net: Optionally use pxe client arch from variableAlexander Graf
The client architecture that we pass to a dhcp server depends on the target payload that we want to execute. An EFI binary has a different client arch than a legacy binary or a u-boot binary. So let's parameterize the pxe client arch field to allow an override via the distro script, so that our efi boot path can tell the dhcp server that it's actually an efi firmware. Signed-off-by: Alexander Graf <agraf@suse.de>
2016-05-27distro: Add efi pxe boot codeAlexander Graf
Now that we can expose network functionality to EFI applications, the logical next step is to load them via pxe to execute them as well. This patch adds the necessary bits to the distro script to automatically load and execute EFI payloads. It identifies the dhcp client as a uEFI capable PXE client, hoping the server returns a tftp path to a workable EFI binary that we can then execute. To enable boards that don't come with a working device tree preloaded, this patch also adds support to load a device tree from the /dtb directory on the remote tftp server.

2016-02-26net: bootp: Add environment variable for timeout periodAlexandre Messier
There is currently one config option (CONFIG_NET_RETRY_COUNT) that is available to tune the retries of the network stack. Unfortunately, it is global to all protocols, and the value is interpreted differently in all of them. Add a new environment variable that directly sets the retry period for BOOTP timeouts. If this new value is not set, the period is still derived from the default number of retries, or from CONFIG_NET_RETRY_COUNT if defined. When both the new variable is set and CONFIG_NET_RETRY_COUNT is defined, the variable has precedence. Signed-off-by: Alexandre Messier <amessier@tycoint.com>
2016-01-28net: Add bootfile in DHCP RequestAlexandre Messier

2016-01-28net: bootp: Ignore packets whose yiaddr is 0Peng Fan
When doing `dhcp`, there is a bad dhcp server in my network which always reply dhcp request with yiaddr 0, which cause uboot can not successfully get ipaddr from the good dhcp server. But the Linux PC can get the ip address even if there is a bad dhcp server. This patch is to fix that even if there is a bad dhcp server, uboot can still get ipaddr and tftp work ok. The way is to ignore the packets from the bad dhcp server by filtering out the yiaddr whose value is 0.
