// Kernel exposes base attach (V0), extended attach (V1/Attach2) and detach.
// This code only builds V0 layer descriptors, so it uses the base attach path.
// Wrapper-side raw attach presets:
// - 0x8/0x9 -> single-image/save-data family (normalized 0x14/0x1C)
// - 0xC/0xD -> download-data/LWFS family (normalized 0x16/0x1E)
// raw bit3 (0x8) sets the DONT_MAP_BM-style mode, raw bit2 (0x4) switches to
// the DD/LWFS family, and raw bit0 (0x1) selects the alternate preset inside a
// family. Firmware pairs bit0 with read-only mount variants, but this is not a
// standalone LVD readonly bit by itself.
// image_type values accepted by validator: 0..0xC (13 values total).
// layer source_type observed: 1=file, 2=device/special source (/dev/sbram0, char/block).
// layer descriptor flag bit0 is "no bitmap file specified".
