2024-03-02ARM: renesas: Rename arch-/mach-rmobile to arch-/mach-renesasMarek Vasut
Rename arch-rmobile to arch-renesas and mach-rmobile to mach-renesas because all the chips are made by Renesas, while only a subset of them is from the R-Mobile line. Use the following command to perform the rename, with manual move of the directories using git mv and manual fix up to arch/arm/Makefile: " $ git grep -l '\<\(arch\|mach\)-rmobile\>' | \ xargs -I {} sed -i 's@\<\(arch\|mach\)-rmobile\>@\1-renesas@g' {} $ sed -i 's@rmobile@renesas@' board/*/*/Kconfig " Signed-off-by: Marek Vasut <marek.vasut+renesas@mailbox.org> Reviewed-by: Paul Barker <paul.barker.ct@bp.renesas.com>

2023-08-19arm: rmobile: Fix off-by-one error in cpuinfoPaul Barker
In rmobile_cpuinfo_idx() there is an off-by-one error in accessing the rmobile_cpuinfo array. At the end of the loop, i is equal to the array size, i.e. rmobile_cpuinfo[i] accesses one entry past the end of the array. The last entry in the array is a fallback value so the loop should count to ARRAY_SIZE(rmobile_cpuinfo) - 1 instead, this will leave i equal to the index of the fallback value if no match is found.

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.

2018-05-07SPDX: 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>
