[U-Boot-Users] [PATCH0/2] Re-do the patch for adding DO_SYNC in flash_write_cmd

[Haiying Wang]

SYNC is defined as 
"	#define SYNC \
        sync; \
        isync
" in include/ppc_asm.tmpl,

and can not be used by .c file, am I right? :-). In fact it is used by
the start.S file for 85xx/83xx/8xx/4xx/5xxx/74xx_7xx.

We need to define SYNC as asm("sync;").
