2019-05-14arm: socfpga: remove re-added ad-hoc reset codeSimon Goldschmidt
commit c5de2b7eae68 ("arm: socfpga: implement proper peripheral reset") has removed the call to 'reset_deassert_peripherals_handoff()' from socfpga gen5 SPL since the reset driver now handles resets. However, commit c1d4b464c8b8 ("ARM: socfpga: Disable bridges in SPL unless booting from FPGA") has re-added this ad-hoc reset code, so that all peripherals were now again enabled instead of letting the drivers enable them by request. While at it, remove this function for gen5 as it should not be used.

2019-04-29ARM: socfpga: Fully unmap the FPGA bridges from L3 spaceMarek Vasut
Instead of just putting the bridges into reset, fully remove the bridges from the L3 main bridge space when disabling them by clearing bits in NIC-301 remap register. Moreover, only touch the 3 LSbits in brgmodrst register as the rest of the bits are undefined.

2019-04-29ARM: socfpga: Factor out handoff register configurationMarek Vasut
Factor out the code for programming preloader handoff register values, the ISWGRP Handoff 0 and 1. These registers later control which bridges are enabled by the "bridge" command on Gen5 devices.

This was never used, is not used anywhere and is just in the way by adding annoying ifdeffery. Get rid of it. Signed-off-by: Marek Vasut <marex@denx.de> Cc: Chin Liang See <chin.liang.see@intel.com> Cc: Dinh Nguyen <dinguyen@kernel.org>
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>
