Document recommended storage layouts per node role:
- Control planes: NVMe boot for fast etcd I/O
- Postgres/storage: eMMC boot + NVMe data at /var/mnt/data
- Compute workers: eMMC only, stateless

Apply overlay patch 0003 (EFI mount path detection for SBC layouts)
in the build so upgrades write firmware/config.txt to the correct
path. Update README with patch 0003, PCIe Gen 3 in features list,
and expanded PCIe Gen 3 instructions.

CM5 on Compute Blade doesn't have an SD slot for booting Raspberry Pi
OS. Use rpiboot recovery mode over USB instead.

Documents the dd + EEPROM configuration approach for booting Talos
from NVMe on RPi5/CM5. Includes BOOT_ORDER, PCIE_PROBE settings,
and optional PCIe Gen 3 configuration.

NVMe kernel driver is already built-in (CONFIG_BLK_DEV_NVME=y). The
expected approach is simply dd'ing the metal image to NVMe and setting
EEPROM BOOT_ORDER=0xf416 + PCIE_PROBE=1. Pending hardware validation.

The overlay was using console=ttyAMA0 (GPIO 14/15) but the RPi5 debug
UART is ttyAMA10 (JST connector between HDMI ports on Pi5, test pads
TP35/TP36 on CM5). Also adds earlycon for early boot output and disables
GPIO UART on Pi5 in config.txt to avoid U-Boot compatibility issues.

Force GRUB instead of sd-boot on arm64 and pass --no-nvram to
grub-install, working around the SetVariableRT firmware limitation
that prevents in-place upgrades on RPi5/CM5 hardware.

Remove the 16K page override from the kernel patch, preserving
upstream Talos's default 4K pages. RPi5 hardware works correctly
with 4K pages — the RPi Foundation's 16K default is a TLB
performance optimization (~5%), not a hardware requirement.
Benefits:
- Correct memory accounting (4x less overhead per page)
- Full software compatibility (jemalloc, Longhorn, F2FS, etc.)
- No OOM surprises on control-plane nodes
- Aligned with upstream Talos kernel config

- Document SetVariableRT upgrade failure, 16K page size implications,
serial console issue, and SBC install disk behavior
- Add production roadmap (4K pages, GRUB boot, serial fix, NVMe)
- Make overlay Go patch conditional: apply only on Go 1.24.x,
skip on 1.25+ where CVEs are already fixed upstream

- Add MPL 2.0 LICENSE file for compliance
- Add license section and upstream attribution to README
- Upgrade provenance attestation from mode=min to mode=max

The image supports both RPi 5 and CM5 (same SoC/RP1), so talos-rpi5
is a better public-facing name. The internal build still produces
an installer image which gets retagged to svrnty/talos-rpi5:<tag>
in the release target.
