Hi, Please backport 78a03b9f8e6b ("riscv: Kconfig: Add select ARM_AMBA to SOC_STARFIVE") to v6.6 Without this, it is not possible to configure the kernel with SPI drivers for the Visionfive 2 board. This one depends a1a5f2c88725 ("dmaengine: pl330: rename _start to prevent build error"), which is already in stable. It should be backported to v6.1 too, but it does not apply cleanly. So I will send a patch for that. Best regards, Nam

[PATCH AUTOSEL 6.1 01/29] hwtracing: hisi_ptt: Handle the interrupt in hardirq context
