The generic loader device supports the U-Boot and Intel HEX executable
formats in addition to the document raw and ELF formats.  Reword the
documentation to include these formats and explain how various options
depend on the executable format.

 Loading Files
 -------------
-The loader device also allows files to be loaded into memory. It can load raw
-files and ELF executable files.  Raw files are loaded verbatim.  ELF executable
-files are loaded by an ELF loader.  The syntax is shown below:
+The loader device also allows files to be loaded into memory. It can load ELF,

     -device loader,file=<file>[,addr=<addr>][,cpu-num=<cpu-num>][,force-raw=<raw>]
 
     <file>      - A file to be loaded into memory
-    <addr>      - The addr in memory that the file should be loaded. This is
-                  ignored if you are using an ELF (unless force-raw is true).
-                  This is required if you aren't loading an ELF.
+    <addr>      - The memory address where the file should be loaded. This is
+                  required for raw images and ignored for non-raw files.
     <cpu-num>   - This specifies the CPU that should be used. This is an
                   optional argument and will cause the CPU's PC to be set to
-                  where the image is stored or in the case of an ELF file to

+                  should only be used for the boot image.
                   This will also cause the image to be written to the specified
                   CPU's address space. If not specified, the default is CPU 0.
     <force-raw> - Setting force-raw=on forces the file to be treated as a raw
-                  image.  This can be used to load ELF files as if they were raw.
