Ingenic T31N with a GalaxyCore GC2053, 64 MiB RAM, 8 MiB SPI NOR and wired
Ethernet. Tested on the physical camera: builds, flashes and boots, with
Ethernet, GC2053 video, H.264/H.265 streaming, automatic day/night switching,
IR-cut control and audio capture/playback all working.
The board has no radio, so the defconfig drops wireless-tools, wpa_supplicant
and the Realtek driver that the nearest sibling carries, along with the QR
onboarding helper that only exists to join a network.
The kernel fragment turns off MMC, the wireless stack, USB and FAT rather than
forking the generic T31 config. Because FAT goes with it, the profile also
overrides /etc/modules: the stock list asks for vfat and exfat, which would no
longer exist.
The exclude list prunes motor.ko and the two sample_pwm modules. Those are
built for every T31 board by ingenic-opensdk regardless of the pinned sensor,
since they sit outside the sensor tree in the openingenic Kbuild, and no board
in the tree had pruned them until now. There is no Kconfig symbol to disable
them, so the exclude list is the only lever.
