boot-deploy needs the AOSP mkbootimg (from android-tools) to build the
header v4 boot.img + vendor_boot.img pair; mkbootimg-osm0sis does not
handle GKI/vendor_boot. Matches the other header-v4 devices (Pixel 6).

The reference-design rail voltages that both sm8550-mtp and the rtwo
downstream share are unchanged, but three rails carry board-specific
ranges in the Motorola DT / device DTB dump:
L11B (panel VDD): 1.20-1.50 V -> 1.23-1.28 V
L1E (USB HS phy): fixed 0.88 V -> 0.88-0.912 V
L1G (UFS VCCQ): fixed 1.20 V -> 1.144-1.256 V

Cross-referenced the LineageOS 23.2 sources (android_device_motorola_rtwo,
sm8550-common, sm8550-devicetrees) and the DTB dumped from the device:
- Fix debug UART: it is GENI SE7 under qupv3_id_0 (@ac0000), not qupv3_id_1.
- Add ramoops (0xae000000/0x60000) and a cont_splash reserved region
(0xb8000000), both matching the stock reserved-memory map.
- Add a simple-framebuffer at 0xb8000000 (1080x2400) so there is an early
console on the panel; deviceinfo screen size corrected to 1080x2400.
- Goodix GT9916 touchscreen on spi4 (SE4), reset TLMM24 / irq TLMM25,
avdd = pm8550 L9B, vddio = pm8550 L10B (new rails L8B/L10B added).
- gpio-keys: volume-up on pm8550 GPIO6; enable PMIC pwrkey + resin
(volume-down).
- SD card: real card-detect on pm8550 GPIO12, vqmmc = L8B.
- modules-initfs: add goodix-berlin + eusb2 phy modules.
Panel/DRM, GPU, modem, WiFi/BT (WCN7850), charger and camera are documented
as TODO in the .dts.

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.
