Subject: [PATCH 1/8] omap: Fix incorrect 730 vs 850 detection

From: [email-masked] (Tony Lindgren)
Date: Fri, 02 Oct 2009 15:37:41 -0700

Commit cd92204924fafbd5c7241dfd12ca3176d542e0c5 added
support for omap850. However, the patch accidentally
removed the wrong ifdef:

 #  define cpu_is_omap730()		1
 # endif
 #endif
+#else
+# if defined(CONFIG_ARCH_OMAP850)
+#  undef  cpu_is_omap850
+#  define cpu_is_omap850()		1
+# endif
+#endif

...

 void omap2_check_revision(void);

 #endif    /* defined(CONFIG_ARCH_OMAP2) || defined(CONFIG_ARCH_OMAP3) */
-
-#endif

Instead of removing removing the #endif at the end of the file,
the #endif before #else should have been removed.

But we cannot have multiple #else statements as pointed out by
Alistair Buxton <[email-masked]>. So the fix is to:

- remove the non-multi-omap special handling, as we need to
  detect between omap730 and omap850 anyways.

- add the missing #endif back to the end of the file
