Volta is the umbrella project for the Radxa Rock 5 ITX+ / boltzmann software stack. Two layers:
Quark — UEFI firmware rebuild via edk2-rk3588 using the Collabora TF-A rockchip branch, upstream OP-TEE master, and the rkbin v1.19 2400 MHz DDR blob; final SPI image padded to 16 MiB with 0x00 (wipes UEFI NVRAM on flash) and written via flashcp –partition.
Neutron — mainline-tracking Linux kernel (linux-rk3588-marfrit off collabora/rockchip-v7.0). State + decision log on its own page.
