Move this uncommon header out of the common header. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-01-07arm: socfpga: Convert system manager from struct to definesLey Foon Tan
Convert system manager for Gen5, Arria 10 and Stratix 10 from struct to defines. Change to get system manager base address from DT node instead of using #define. Signed-off-by: Ley Foon Tan <ley.foon.tan@intel.com> Reviewed-by: Simon Goldschmidt <simon.k.r.goldschmidt@gmail.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>
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>
2015-08-08arm: socfpga: scan: Add code to get FPGA IDDinh Nguyen
Add code to get the FPGA type for Altera's SoCFPGA family of FPGA. The code uses the scan manager to send jtag pulses that will return the FPGA ID. Signed-off-by: Dinh Nguyen <dinguyen@opensource.altera.com>
2015-08-08arm: socfpga: scan: Factor out IO chain programmingMarek Vasut
Factor out the code which sends JTAG instruction followed by data into separate function to tidy the code up a little. Signed-off-by: Marek Vasut <marex@denx.de> Acked-by: Dinh Nguyen <dinguyen@opensource.altera.com>
2015-08-08arm: socfpga: scan: Clean up horrible macrosMarek Vasut
Clean up the horrible macros present in the scan_manager.h . Firstly, the function scan_mgr_io_scan_chain_prg() is static, yet all the macros are used only within it, thus there is no point in having them in the header file. Moreover, the macros are just making the code much less readable, so remove them instead. Signed-off-by: Marek Vasut <marex@denx.de> Acked-by: Dinh Nguyen <dinguyen@opensource.altera.com>
2015-08-08arm: socfpga: scan: Introduce generic JTAG accessorMarek Vasut
Introduce generic function for accessing the JTAG scan chains in the SCC manager. Make use of this function throughout the SCC manager to replace the ad-hoc writes to registers and make the code less cryptic.

2015-08-08arm: socfpga: scan: Clean up scan_chain_engine_is_idle()Marek Vasut
Rework this function so it's clear that it is only polling for certain bits to be cleared. Add kerneldoc. Fix it's return value to be either 0 on success and -ETIMEDOUT on error and propagate this through the scan manager code.

2015-08-08arm: socfpga: scan: Zap iocsr_scan_chain*_table()Marek Vasut
Introduce accessor iocsr_get_config_table() for retrieving IOCSR config tables. This patch is again trimming down the namespace polution. The IOCSR config tables are used only by scan manager, they are generated by qts and are board specific. Before this patch, the approach to use these tables in scan manager was to define an extern variable to silence the compiler and compile board-specific iocsr_config.c into U-Boot which defined those extern variables. Furthermore, since these are tables and the scan manager needs to know the size of those tables, iocsr_config.h is included build-wide. This patch wraps all this into a single accessor which takes the scan chain ID and returns pointer to the table and it's size. All this is wrapped in wrap_iocsr_config.c board-specific file. The file includes the iocsr_config.c (!) to access the original tables and transitively iocsr_config.h . It is thus no longer necessary to include iocsr_config.h build-wide and the namespace polution is trimmed some more. Signed-off-by: Marek Vasut <marex@denx.de>
2015-08-08arm: socfpga: scan: Zap redundant params in scan_mgr_io_scan_chain_prg()Marek Vasut
It is sufficient to pass in the scan chain ID into the function to determine the remaining two parameters, so drop those params and determine them locally in the function. The big-ish switch in the function is temporary and will be replaced by a proper function call in subsequent patch. Signed-off-by: Marek Vasut <marex@denx.de>
2015-08-08arm: socfpga: scan: Staticize scan_mgr_io_scan_chain_prg()Marek Vasut
This function is never used outside of scan_manager.c , so make it static. Zap the prototype in scan_manager.h and move the documentation above the function. Make the documentation kerneldoc compliant. Signed-off-by: Marek Vasut <marex@denx.de>
