Bring-up for the Motorola Moto Edge 40 Pro (codename "rtwo", SM8550 / Snapdragon 8 Gen 2). New linux-postmarketos-qcom-sm8550 aport: - Built from the postmarketOS soc/qcom-sm8550 tree (branch bringup, 6.13-rc3, commit 22591bbc). - Kernel config is generated at build time from the in-tree upstream defconfig plus the repo's pmos.config and devices.config fragments. - Ships a WIP sm8550-motorola-rtwo.dts: SoC + PMICs + the sm8550-mtp regulator tree, UART7 debug console, USB in high-speed peripheral mode, UFS and SD card. Display panel, touchscreen, modem, WiFi/BT, GPU zap shader and reserved-memory carveouts still need to be described from Motorola's downstream sources. device-motorola-rtwo: - deviceinfo completed from bootimg analysis of the stock boot.img: Android boot header v4, 4096-byte pages, no qcdt, fastboot flashing. Added screen geometry, UFS sector size and a serial getty; framebuffer disabled until the panel works. - Depends on the new kernel, soc-qcom and mkbootimg. Both packages still need 'pmbootstrap checksum' for the kernel tarball and a real boot test; see the TODO comments in the APKBUILDs and the .dts.
