2025-08-27net: fm: NULL check dev before dereferenceAndrew Goodbody
In fm_eth_bind there is a dereference of dev before it is NULL checked. Add a NULL check before the first dereference and remove a later NULL check that is now redundant. This issue was found by Smatch. Signed-off-by: Andrew Goodbody <[email protected]> Signed-off-by: Peng Fan <[email protected]>
2025-08-27net: fm: Correct test for timeoutAndrew Goodbody
In bmi_rx_port_disable and bmi_tx_port_disable the use of post-decrement on the test in the while loop for a timeout means that timeout will be equal to -1 on exit in that case.

2021-09-28net: freescale: replace usage of phy-mode = "sgmii-2500" with "2500base-x"Vladimir Oltean
After the discussion here: https://lore.kernel.org/netdev/20210603143453.if7hgifupx5k433b@pali/ which resulted in this patch: https://patchwork.kernel.org/project/netdevbpf/patch/[email protected]/ and many other discussions before it, notably: https://patchwork.kernel.org/project/linux-arm-kernel/patch/[email protected]/ it became apparent that nobody really knows what "SGMII 2500" is. Certainly, Freescale/NXP hardware engineers name this protocol "SGMII 2500" in the reference manuals, but the PCS devices do not support any "SGMII" specific features when operating at the speed of 2500 Mbps, no in-band autoneg and no speed change via symbol replication . So that leaves a fixed speed of 2500 Mbps using a coding of 8b/10b with a SERDES lane frequency of 3.125 GHz. In fact, "SGMII 2500 without in-band autoneg and at a fixed speed" is indistinguishable from "2500base-x without in-band autoneg", which is precisely what these NXP devices support. So it just appears that "SGMII 2500" is an unclear name with no clear definition that stuck. As such, in the Linux kernel, the drivers which use this SERDES protocol use the 2500base-x phy-mode. This patch converts U-Boot to use 2500base-x too, or at least, as much as it can. Note that I would have really liked to delete PHY_INTERFACE_MODE_SGMII_2500 completely, but the mvpp2 driver seems to even distinguish between SGMII 2500 and 2500base-X. Namely, it enables in-band autoneg for one but not the other, and forces flow control for one but not the other. This goes back to the idea that maybe 2500base-X is a fiber protocol and SGMII-2500 is an MII protocol (connects a MAC to a PHY such as Aquantia), but the two are practically indistinguishable through everything except use case. NXP devices can support both use cases through an identical configuration, for example RX flow control can be unconditionally enabled in order to support rate adaptation performed by an Aquantia PHY. At least I can find no indication in online documents published by Cisco which would point towards "SGMII-2500" being an actual standard with an actual definition, so I cannot say "yes, NXP devices support it".

2020-12-13dm: treewide: Rename auto_alloc_size members to be shorterSimon Glass
This construct is quite long-winded. In earlier days it made some sense since auto-allocation was a strange concept. But with driver model now used pretty universally, we can shorten this to 'auto'. This reduces verbosity and makes it easier to read. Coincidentally it also ensures that every declaration is on one line, thus making dtoc's job easier. Signed-off-by: Simon Glass <[email protected]>
2020-07-17treewide: convert bd_t to struct bd_info by coccinelleMasahiro Yamada
The Linux coding style guide (Documentation/process/coding-style.rst) clearly says: It's a **mistake** to use typedef for structures and pointers. Besides, using typedef for structures is annoying when you try to make headers self-contained. Let's say you have the following function declaration in a header: void foo(bd_t *bd); This is not self-contained since bd_t is not defined. To tell the compiler what 'bd_t' is, you need to include <asm/u-boot.h> #include <asm/u-boot.h> void foo(bd_t *bd); Then, the include direcective pulls in more bloat needlessly. If you use 'struct bd_info' instead, it is enough to put a forward declaration as follows: struct bd_info; void foo(struct bd_info *bd); Right, typedef'ing bd_t is a mistake. I used coccinelle to generate this commit. The semantic patch that makes this change is as follows: <smpl> @@ typedef bd_t; @@ -bd_t +struct bd_info </smpl> Signed-off-by: Masahiro Yamada <[email protected]>

Probe the FMan MACs based on the device tree while retaining the legacy code/functionality. One notable change introduced here is that, for DM_ETH, the name of the interfaces is corrected to the fmX-macY format, that avoids the referral to the MAC block names which were incorrect for FMan v3 devices (i.e. DTSEC, TGEC) and had weird formatting (i.e. FM1@DTSEC6, FM1@TGEC1).

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 <[email protected]>
