2018-12-07ARM: rmobile: Fix to enable icache early in Gen3Takeshi Kihara
This patch fixes the problem that u-boot will not start unless icache is enabled early. Signed-off-by: Takeshi Kihara <takeshi.kihara.df@renesas.com> Signed-off-by: Hiroyuki Yokoyama <hiroyuki.yokoyama.vx@renesas.com> Signed-off-by: Marek Vasut <marek.vasut+renesas@gmail.com>
2018-12-07ARM: rcar_gen3: fix protection area access errorTakeshi Kihara
This patch fixes the problem that "main memory domain AXI secure access protection error" occurs. Exclude the area (0x43f00000 to 0x47DFFFFF) set by DBSC from the map area.

2018-11-02ARM: rmobile: Generate fitting mem_map on Gen3Marek Vasut
Patch "ARM: rmobile: Mark 4-64GiB as DRAM on Gen3" marked the entire 64bit DRAM space as cachable. On CortexA57, this might result in odd side effects, where the CPU tries to prefetch from those areas and if there is no DRAM backing them, CPU bus hang can happen. This patch fixes it by generating the mem_map structure based on the actual memory layout obtained from the DT, thus not marking areas without any DRAM behind them as cachable.

2018-10-03ARM: rmobile: Mark 4-64GiB as DRAM on Gen3Marek Vasut
Mark area 0x1_0000_0000 - 0x10_0000_0000 as DRAM on Gen3 as the chip is capable of addressing that and U-Boot can make use of it. This patch prevents exception when accessing those areas. Signed-off-by: Marek Vasut <marek.vasut+renesas@gmail.com> Cc: Nobuhiro Iwamatsu <iwamatsu@nigauri.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>
2018-04-11ARM: rmobile: Fix the memory map on Gen3Marek Vasut
Fix up the memory map on Gen3 to match datasheet properly. This simplifies the memory map setup as well, since we do no longer need this massive complexity. Signed-off-by: Marek Vasut <marek.vasut+renesas@gmail.com> Cc: Nobuhiro Iwamatsu <iwamatsu@nigauri.org>

2017-11-30ARM: rmobile: Unify memory map for RCar Gen3Marek Vasut
Unify the R7A7795 and R8A7796 memory maps in memmap-gen3 and, for now, select which one is used based on which SoC is selected. Since this is done in C code instead of statically assigned now, the decision can be taken by PRR SoC match as well, which will be done in a subsequent patch.
