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: Split out image writing from pre/post operationsRobert Hancock
This is in preparation for adding slave serial programming support, which uses the same pre/post operations as slave SelectMAP, to avoid duplicating code. Signed-off-by: Robert Hancock <hancock@sedsystems.ca> 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>
2015-11-19Move console definitions into a new console.h fileSimon Glass
The console includes a global variable and several functions that are only used by a small subset of U-Boot files. Before adding more functions, move the definitions into their own header file. Signed-off-by: Simon Glass <sjg@chromium.org>
2014-05-20fpga: Define bitstream type based on command selectionMichal Simek
Clean up partial, full and compressed bitstream handling. U-Boot supports full bitstream loading and partial based on detection which is not 100% correct. Extending fpga_load/fpga_loadbitstream() with one more argument which stores bitstream type. Signed-off-by: Michal Simek <michal.simek@xilinx.com>

2013-04-01Consolidate bool typeYork Sun
'bool' is defined in random places. This patch consolidates them into a single header file include/linux/types.h, using stdbool.h introduced in C99. All other #define, typedef and enum are removed. They are all consistent with true = 1, false = 0. Replace FALSE, False with false. Replace TRUE, True with true. Skip *.py, *.php, lib/* files. Signed-off-by: York Sun <yorksun@freescale.com>
