riscv: dts: sophgo: cv180x: fix USB dwc2 FIFO sizes

2026-02-26T23:00:50+00:00

[ Upstream commit 03ea8676919af21b99bea01f18ef1a271d19f92f ] I've tested the current dwc2 FIFO configuration and found that USB device mode breaks in ECM mode when transmitting frames larger than 128 bytes. For example, large ICMP packets or iperf3 traffic cause the USB link to hang and eventually disconnect without any messages in dmesg. After switching to more conservative FIFO sizes, ECM becomes stable and no longer drops the connection. iperf3 now shows ~130 Mbit/s RX and ~100 Mbit/s TX on SG2002 (MilkV Duo 256M). Fix the FIFO sizes accordingly. Signed-off-by: Anton D.

riscv: boot: Always make Image from vmlinux, not vmlinux.unstripped

2025-12-31T02:57:55+00:00

Since commit 4b47a3aefb29 ("kbuild: Restore pattern to avoid stripping .rela.dyn from vmlinux") vmlinux has .rel*.dyn preserved. Therefore, use vmlinux to produce Image, not vmlinux.unstripped. Doing so fixes booting a RELOCATABLE=y Image with kexec. The problem is caused by this chain of events: - Since commit 3e86e4d74c04 ("kbuild: keep .modinfo section in vmlinux.unstripped"), vmlinux.unstripped gets a .modinfo section. - The .modinfo section has SHF_ALLOC, so it ends up in Image, at the end of it. - The Image header's image_size field does not expect to include .modinfo and does not account for it, since it should not be in Image. - If .modinfo is large enough, the file size of Image ends up larger than image_size, which eventually leads to it failing sanity_check_segment_list(). Using vmlinux instead of vmlinux.unstripped means that the unexpected .modinfo section is gone from Image, fixing the file size problem.

Pull SoC devicetree updates from Arnd Bergmann: "Three new SoCs got added in existing arm64 chip families: - Renesas R-Car X5H (R8A78000) is a new generation of automotive SoCs, based on 16 Cortex-A720 (Armv9.2) cores, which makes the the currently highest-perforance embedded SoC. - TI AM62L is a new variant of the AM62 family of industrial SoCs, this one comes without a GPU. - Qualcomm MSM8937 (Snapdragon 430) is an older mobile phone chip based on Cortex-A53, and closely related to MSM8917 (Snapdragn 425), which we already support. In addition, there are a good number of newly supported machines across SoC families: - Two Aspeed AST2600 (Cortex-A7) based BMC setups for large servers - Mobile Phones and tables based on Mediatek MT6582, Nvidia Tegra124, Qualcomm MSM8937 and Qualcomm MSM8939, - Two Laptops based on Qualcomm SoCs: one using the older sdm850, the other using x1p42100. - One Router based on Rockchips RK3568 - 24 variants of the Enclustra Mercury system-on-module, all based on 32-bit Intel/Altera SocFPGA chips, plus two boards using 64-bit SocFPGA Agilex chips.. - 30 industrial/embedded boards and single-board computers, using various chips from NXP, Rockchips, Mediatek, TI, Amlogic, Qualcomm, Spacemit, and Starfive.

RISC-V Devicetrees for v6.19 MAINTAINERS: There's some re-jigging of things to reduce duplication, by moving me into the StarFive entry and my tree into the Microchip one. The other platforms that I look after (SiFive and Canaan) are marked as Odd Fixes to better represent their status. Nothing functionally changes. Microchip: Add adc and mmc nodes for the Beagle-V Fire. SiFive: Add pwm fans to the unmatched board. StarFive: Add the Orange PI RV board, another VisionFive 2 derived SBC. This required moving a mmc related nodes out of the common file, into .dts. Yet more things moved out of the common file when the VisionFive 2 Lite boards were added, which use the JH7110S SoC instead of the JH7110. The difference here between SoCs is just temperature and frequency ranges, but the boards differ enough that the pool of common nodes decreases a little further. There's an eMMC and an SD variant here, that are different SKUs, bringing the total new StarFive boards to three.
