Hello, This mini-series adds initial support for the Realtek RTD1295 SoC and the Zidoo X9S TV box. v3 changes #address-cells, #size-cells and ranges. With these patches CPU0 can be booted with earlycon. PSCI doesn't work despite present in the vendor device tree; as enable-method it instead used a custom "rtk-spin-table" that I sadly have no source code of. The UARTs use a custom interrupt controller that I again lack source code of; with interrupts = <GIC_SPI 41 IRQ_TYPE_LEVEL_HIGH> it can boot into an initrd. The boot process is slightly twisted: The files need to be loaded from a 32-bit U-Boot, then boot into 64-bit U-Boot where the kernel can be booted. Similar to my previous Amlogic S905 work, the TEXT_OFFSET poses a problem, so a uImage needs to be used (or the kernel patched) for load address 0x00280000. I haven't succeeded loading an initrd via bootm/booti; but as quick workaround initrd=$rootfs_loadaddr,0x$filesize can manually be specified in $bootargs. Cf. https://en.opensuse.org/HCL:Zidoo_X9S More experimental patches at: https://github.com/afaerber/linux/commits/rtd1295-next Have a lot of fun!
