+/* this file define a standard header used as a first entry point to
+ * exchange information between firmware/driver and driver.  The
+ * header structure can be anywhere in the mcp. It will usually be in
+ * the .data section, because some fields needs to be initialized at
+ * compile time.
+ * The 32bit word at offset MX_HEADER_PTR_OFFSET in the mcp must
+ * contains the location of the header. 
+ * 
+ * Typically a MCP will start with the following:
+ * .text
+ * .space 52    ! to help catch MEMORY_INT errors
+ * bt start     ! jump to real code
+ * nop
+ * .long _gen_mcp_header
+ * 
+ * The source will have a definition like:
+ * 
+ * mcp_gen_header_t gen_mcp_header = {
+ * .header_length = sizeof(mcp_gen_header_t),
+ * .mcp_type = MCP_TYPE_XXX,
+ * .version = "something $Id: mcp_gen_header.h,v 1.2 2006/05/13 10:04:35 bgoglin Exp $",
+ * .mcp_globals = (unsigned)&Globals
+ * };
