[ECOS] error linking tk's eb40 and my eb40a hal

[Tim Drury]

I get a strange error when compiling vectors.S.  This occurs for
both Thomas' eb40 hal (latest patch) and my eb40a hal which is
a copy of his.  This _only_ occurs when building redboot for ROM -
everything works fine for the RAM version.

Sometimes these things are hard to pin down.  Try using #if 0/#endif
within that file to isolate the line that's causing the problems.

*sigh*  
I'll give my usual disclaimer: I've been out of embedded systems for two
years.  It's amazing what you forget.  This is truly one of the best 
debugging techniques around.

I needed  '#include <cyg/hal/var_io.h>' in hal_platform_setup.h because
Thomas moved the at91 register #defines from hal_io.h to var_io.h
and I didn't catch it.

BTW: Thomas, the eb40 hal _does_ work.  When I applied your patch
I didn't delete your old stuff which had an old hal_platform_setup.h
in the 'var' tree which was bad.  After deleting it and hal_platform_ints.h
and adding the line above, both eb40 and eb40a compile for ROM.
Now on to testing....

Thanks again folks.
