+# Protected Virtual Machine Firmware
+
+## Configuration Data Format
+
+pvmfw will expect a [header] to have been appended to its loaded binary image
+at the next 4KiB boundary. It describes the configuration data entries that
+pvmfw will use and, being loaded by the pvmfw loader, is necessarily trusted.
+
+The layout of the configuration data is as follows:
+
+```
++===============================+
+|          pvmfw.bin            |
++~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~+
+|  (Padding to 4KiB alignment)  |
++===============================+ <-- HEAD
+|      Magic (= 0x666d7670)     |
++-------------------------------+
+|           Version             |
++-------------------------------+
+|   Total Size = (TAIL - HEAD)  |
++-------------------------------+
+|            Flags              |
++-------------------------------+
+|           [Entry 0]           |
+|  offset = (FIRST - HEAD)      |
+|  size = (FIRST_END - FIRST)   |
++-------------------------------+
+|           [Entry 1]           |
+|  offset = (SECOND - HEAD)     |
+|  size = (SECOND_END - SECOND) |
++-------------------------------+
+|              ...              |
++-------------------------------+
+|           [Entry n]           |
++~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~+
+| (Padding to 8-byte alignment) |
++===============================+ <-- FIRST
+|        {First blob: BCC}      |
++~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~+ <-- FIRST_END
+| (Padding to 8-byte alignment) |
++===============================+ <-- SECOND
+|        {Second blob: DP}      |
++~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~+ <-- SECOND_END
+| (Padding to 8-byte alignment) |
++===============================+
+|              ...              |
++===============================+ <-- TAIL
+```
+
+Where the version number is encoded using a "`major.minor`" as follows
+
+```
+((major << 16) | (minor & 0xffff))
+```
+
+and defines the format of the header (which may change between major versions),
+its size and, in particular, the expected number of appended blobs. Each blob is
+referred to by its offset in the entry array and may be mandatory or optional
+(as defined by this specification), where missing entries are denoted by a zero
+size. It is therefore not allowed to trim missing optional entries from the end
+of the array. The header uses the endianness of the virtual machine.
+
+The header format itself is agnostic of the internal format of the individual
+blos it refers to. In version 1.0, it describes two blobs:
+
+- entry 0 must point to a valid [BCC Handover]
+- entry 1 may point to a [DTBO] to be applied to the pVM device tree
+
+[header]: src/config.rs
+[BCC Handover]: https://pigweed.googlesource.com/open-dice/+/825e3beb6c6efcd8c35506d818c18d1e73b9834a/src/android/bcc.c#260
