A previous commit introduced the use of binman in the SPL.
After the binman_sym call over the 'pos' symbol, the output value is checked against BINMAN_SYM_MISSING (-1UL). According to the documentation (tools/binman/README), when it comes to the 'pos' attribute:
pos: This sets the position of an entry within the image. The first byte of the image is normally at position 0. If 'pos' is not provided, binman sets it to the end of the previous region, or the start of the image's entry area (normally 0) if there is no previous region.
So instead of checking if the return value is BINMAN_SYM_MISSING, we should check if the value is not null.
The failure happens when using both files sunxi-spl(-with-ecc).bin and u-boot-dtb.bin instead of u-boot-sunxi-with-spl.bin. This is because u-boot-dtb.bin does not have the U-Boot header while it is present in u-boot-sunwi-with-spl.bin. Not having the header forces the SPL to discover where it should load U-Boot. The binman_sym call is supposed to do that but fails. Because of the wrong check, the destination address was set to 0 while it should have been somewhere in RAM. This, obviously, stalls the board.
