2022-12-05net: xilinx_axi: add PCS/PMA PHYAndy Chiu
If we bridge an external PHY to Xilinx's PCS/PMA PHY and would like to get and set the real status of the PHY facing the external world. Then we should phy_connect() to the external PHY instead of the PCS/PMA one. Thus, we add a pcs-handle DT entry, which have been merged in Linux, and leave the configuration of it to the driver itself. Unlike Linux, where the PCS/PMA PHY is managed by phylink, managing the PCS/PMA PHY is only internal to the driver in U-Boot. The PCS/PMA PHY pressents only when the phy-mode is configured as SGMII or 1000Base-X, so it is always 1 Gbps and full-duplex and we may skip passing link information out.

If we just use fdtdec_get_addr_size_fixed to get "reg" it will use 64bit address cell to get the base address. soc { #address-cells = <1>; #size-cells = <1>; compatible ="SiFive,FU500-soc", "fu500-soc", "sifive-soc", "simple-bus"; ranges; L28: axidma@30010000 { #dma-cells = <1>; compatible = "xlnx,axi-dma-1.00.a"; axistream-connected = <&L27>; axistream-control-connected = <&L27>; clocks = <&L1>; interrupt-parent = <&L6>; interrupts = <32 33>; reg = <0x30010000 0x4000>; fdtdec_get_addr_size_fixed: reg: addr=3001000000004000 We should get the base address through its parent's address-cells and size-cells settings.

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>
