I had to fix two issues:

ERROR: "(foo*)" should be "(foo *)"
#200: FILE: board/calao/sbc35_a9g20/sbc35_a9g20.c:174:
+		(void*)CONFIG_SYS_SDRAM_BASE,

Added removal of SBC35_9G20 from MAKEALL.

Configuring for sbc35_a9g20_nandflash - Board: sbc35_a9g20, Options:
AT91SAM9G20,SYS_USE_NANDFLASH
   text	   data	    bss	    dec	    hex	filename
 196136	   5980	 267224	 469340	  7295c	./u-boot
Configuring for sbc35_a9g20_eeprom - Board: sbc35_a9g20, Options:
AT91SAM9G20,SYS_USE_EEPROM
   text	   data	    bss	    dec	    hex	filename
 194984	   5984	 267244	 468212	  724f4	./u-boot

Removal Patch for this board set to "Non Applicable".

Thanks,
Reinhard
