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>
2018-04-27Remove unnecessary instances of DECLARE_GLOBAL_DATA_PTRTom Rini
We have a large number of places where while we historically referenced gd in the code we no longer do, as well as cases where the code added that line "just in case" during development and never dropped it. Signed-off-by: Tom Rini <trini@konsulko.com>
2017-11-26arm: socfpga: Enhance FPGA program write rbf data with size >= 4 bytesTien Fong Chee
Existing FPGA program write is always assume RBF data >= 32 bytes, so any rbf data less than 32 bytes writing to FPGA would be failed. This patch enhances the FPGA program write to support rbf data with size >= 4 bytes. Signed-off-by: Tien Fong Chee <tien.fong.chee@intel.com>
2017-07-26arm: socfpga: Restructure FPGA driver in the preparation to support A10Tien Fong Chee
Move FPGA driver which is Gen5 specific code into Gen5 driver file and keeping common FPGA driver intact. All the changes are still keeping in driver/fpga/ and no functional change. Subsequent patch would move FPGA manager driver from arch/arm into driver/fpga/.

2016-09-23treewide: replace #include <asm/errno.h> with <linux/errno.h>Masahiro Yamada
Now, arch/${ARCH}/include/asm/errno.h and include/linux/errno.h have the same content. (both just wrap <asm-generic/errno.h>) Replace all include directives for <asm/errno.h> with <linux/errno.h>.

2016-02-04Revert "arm: socfpga: set the fpga global bit to disable HPS to FPGA signals"Dinh Nguyen
Apparently, the logic for the FPGA global bit is not universal between Gen5 and Gen10 devices is not the same. Disabling this bit, while applicable to Gen10 devices, will break FPGA programming on Gen5 devices. Signed-off-by: Dinh Nguyen <dinguyen@opensource.altera.com>

We should be setting the FPGA Interface Group global bit that will correctly disable all interfaces between the FPGA and HPS. Signed-off-by: Dinh Nguyen <dinguyen@opensource.altera.com>
2015-08-08arm: socfpga: Fix FPGA bitstream programming routineMarek Vasut
In case the FPGA bitstream is aligned to 4 bytes, skip the part of the assembler which handles unaligned bitstream. Otherwise, that part will loop indefinitelly. Signed-off-by: Marek Vasut <marex@denx.de> Cc: Dinh Nguyen <dinguyen@opensource.altera.com>
2014-10-06arm: socfpga: fpga: Add SoCFPGA FPGA programming interfacePavel Machek
Add code necessary to program the FPGA part of SoCFPGA from U-Boot with an RBF blob. This patch also integrates the code into the FPGA driver framework in U-Boot so it can be used via the 'fpga' command.
