+// CUP Package files structure:
+//   | SIZE |  ADDR  |      BINARY        |  PAD    | CRC  | Next Archive
+//   |  4B  |   4B   |        XB          | 0-3 B   |  4B  | ...
+//   |                                              |      | ...
+//   |<------------------CRC----------------------->|      | ...
+//   |<-----------------------SIZE------------------------>| ...
+//
+// Archive must be word-aligned
+// Archives can be concatenated
+// ADDR is the destination address of the installed archive
+// SIZE accounts for whole archive (including itself)
+// Binary size must be multiple of word (i.e pad=4)
+// CRC calculated on whole archive (obviously excluding itself)
+// Values (size,addr) are stored little-endian

+///         Origin) as BOOT/CUP access it in a hardcoded way.
