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>
2018-04-09axi: ethernet: Added support for 64 bit addressing for axi-ethernetVipul Kumar

2017-11-29net: xilinx_axi_emac: Use readl and writel for io opsSiva Durga Prasad Paladugu
This patch uses readl and writel instead of in_be32 and out_be32 for io ops as these internally uses readl, writel for microblaze and for Zynq, ZynqMP there is no need of endianness conversion and readl, writel should work straightaway. This patch starts supporting the driver for Zynq and ZynqMP platforms. Signed-off-by: Siva Durga Prasad Paladugu <sivadur@xilinx.com> Signed-off-by: Michal Simek <michal.simek@xilinx.com>
2017-11-29net: xilinx_axi_emac: Add support for non processor modeSiva Durga Prasad Paladugu
Add support for non processor mode, this mode doesn't have access to some of the registers and hence this patch bypasses it and also length has to be calculated from status instead of app4 in this mode. Signed-off-by: Siva Durga Prasad Paladugu <sivadur@xilinx.com>
2017-11-28net: xilinx_axi_emac: Read dma address using fdtdec_get_addrSiva Durga Prasad Paladugu
Read dma address using fdtdec_get_addr as it checks for address cells and size cells and reads the address properly. fdtdec_get_int always assume address is of int size which goes wrong if using it on 64-bit architecture.

2017-06-01dm: Rename dev_addr..() functionsSimon Glass
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.

2017-02-08dm: core: Replace of_offset with accessorSimon Glass

axi_emac, emaclite and gem have the same issue with registering multiple instances with mdio busses. mdio bus name has to be uniq but drivers are setting up only one name for all.
