2019-07-30fpga: virtex2: Add slave serial programming supportRobert Hancock
This adds support for slave serial programming, in addition to the previously supported slave SelectMAP mode. There are two ways that this can be used: -Using the clk and wdata callbacks in order to write image data one bit at a time using pure bit-banging. This works, but is rather painfully slow with typical image sizes. -By specifying the wbulkdata callback instead, the image loading process can be offloaded to SPI hardware. In this mode the clk and wdata callbacks do not need to be specified. This allows the image to be loaded much faster, taking only a few seconds with even relatively large images. Slave serial programming has been tested on the Kintex-7 series of FPGAs. Signed-off-by: Robert Hancock <hancock@sedsystems.ca> Signed-off-by: Michal Simek <michal.simek@xilinx.com>
2019-07-30fpga: virtex2: Add additional clock cycles after DONE assertionRobert Hancock
Some Xilinx FPGA configuration options can result in the startup sequence extending past the end of the FPGA bitstream. Continue applying CCLK clock cycles for 8 cycles after DONE is asserted in order to ensure the startup sequence is complete, as recommended by Xilinx.

2019-07-30fpga: virtex2: added Kconfig optionRobert Hancock
Add an option to allow this driver to be selected with Kconfig.

2018-09-26fpga: zynqmp: Modify PL bitstream loading sequenceSiva Durga Prasad Paladugu
This patch modifies PL bitstream loading sequence as per latest Xilfpga which supports all variants of bitstream images generated from vivado and from bootgen. With this new change in Xilfpga, uboot doesn't need to validate and swap bitstream as it will be taken care inside Xilfpga. ZynqMP PL driver now checks for supporting PMUFW version before skipping the validation and swap sequence as there can be old PMUFW which doesn't supports this feature. In this case, driver uses old way of PL bitstream loading sequence. Signed-off-by: Siva Durga Prasad Paladugu <siva.durga.paladugu@xilinx.com> Signed-off-by: Michal Simek <michal.simek@xilinx.com>

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>
