ram: renesas: dbsc5: Add Renesas R-Car Gen5 DBSC5 driver

2026-06-16T03:38:25Z

Add Renesas R-Car Gen5 DBSC5 DRAM controller driver. This driver is currently capable of bringing LPDDR5X DRAM on Renesas R-Car X5H Ironhide board. Further boards can be supported by supplying board specific DRAM configuration data via dbsc5_get_board_data(). The driver reuses parts of previous DBSC5 driver, but due to hardware changes, can not be fully integrated into existing DBSC and DRAM driver, therefore the currentl DBSC and DRAM drivers are moved into R8A779G0 V4H specific files, and the R8A78000 X5H files are added in parallel. The Gen5 DBSC driver is meant to be used in RSIP context, while the Gen4 DBSC driver is meant to be used in SPL, therefore the Kconfig conditionals have been adjusted to match.

ram: renesas: rtvram: Add support for Renesas R-Car Gen5

2026-06-16T03:38:25Z

Add support for Renesas R-Car Gen5 R8A78000 SoC into RT-VRAM initialization driver. The changes are only a slight adjustment to the register programming, therefore reuse the existing RT-VRAM driver and parametrize those changes using driver data. Signed-off-by: Marek Vasut

treewide: Clean up DECLARE_GLOBAL_DATA_PTR usage

2026-02-17T19:50:22Z

Remove DECLARE_GLOBAL_DATA_PTR from files where gd is not used, and drop the unnecessary inclusion of asm/global_data.h. Headers should be included directly by the files that need them, rather than indirectly via global_data.h.

sunxi: extend R528/T113-s3/D1(s) DRAM initialisation

2026-01-25T23:29:32Z

The T113-s4 SoC is using the same die as the T113-s3, but comes with 256MiB of co-packaged DRAM. Besides the doubled size, the DRAM chip seems to be connected slightly differently, which requires to use a different pin remapping. Extend the DRAM initialisation code to add support for the T113-S4 aka T113M4020DC0 by checking the SoC's CHIPID, which is stored in the first word of the SID efuses.

kbuild: Bump the build system to 6.1

2026-01-02T16:28:14Z

Our last sync with the kernel was 5.1. We are so out of sync now, that tracking the patches and backporting them one by one makes little sense and it's going to take ages. This is an attempt to sync up Makefiles to 6.1. Unfortunately due to sheer amount of patches this is not easy to review, but that's what we decided during a community call for the bump to 5.1, so we are following the same guidelines here.

ram: starfive: drop references to 16GB memory size

2025-12-08T04:10:26Z

16GB memory size is not addressable on StarFive JH-7110 SoC because the DRAM uncached alias begins at +8GB offset from start of DRAM. The logic for 16GB memory size is a fall-through to the default for an unknown size. Let's drop this unnecessary 16GB memory size and rely on the case default. Signed-off-by: E Shattow
