[U-Boot] [PATCH 1/4] microblaze: Fix compilation warning in ext2_find_next_zero_bit

[Michal Simek]

ext2_find_next_zero_bit must be also static if __swab32 is also static.

Warning:
include/asm/bitops.h:369:22: warning: '__fswab32' is static but
used in inline function 'ext2_find_next_zero_bit'
which is not static [enabled by default]

[U-Boot] [PATCH 3/4] microblaze: Flush caches before enabling them

[Michal Simek]

Flushing caches is necessary because of soft reset
which doesn't clear caches.

I'd rather see it done the other way -- drop the inline and let compiler decide. 
What are the size penalties ?

Can the flushes not remain in the C code?

Better commit message would really help ... esp. if you could explain the

With inline
    text	   data	    bss	    dec	    hex	filename
  361914	  14698	 232344	 608956	  94abc	./u-boot

without inline
    text	   data	    bss	    dec	    hex	filename
  361922	  14698	 232368	 608988	  94adc	./u-boot

But the problem is that I can see a lot of warnings that this function is unused.
u-boot/include/asm/bitops.h:322:22: warning: 'ext2_find_next_zero_bit' defined but not used [-Wunused-function]

FYI: I have just grepped source tree and I see that the same solution is used by blackfin/mips and powerpc.

$ grep -rn "ext2_find_next_zero_bit" arch/ | grep static
arch/microblaze/include/asm/bitops.h:322:static inline unsigned long ext2_find_next_zero_bit(void *addr,
arch/blackfin/include/asm/bitops.h:324:static __inline__ unsigned long ext2_find_next_zero_bit(void *addr,

DAMN :-( Maybe we should focus on --gc-sections for whole u-boot. Anyway, I'd 
say apply this and then start working on the --gc-sections.
