I'm working on a custom board that is similar to the ml507 (with a virtex 5 powerpc 440), and I ran across this error compiling u-boot:
fdt.c: In function '__ft_board_setup': fdt.c:43: error: 'EBC_NUM_BANKS' undeclared (first use in this function) fdt.c:43: error: (Each undeclared identifier is reported only once fdt.c:43: error: for each function it appears in.) fdt.c:43: warning: unused variable 'ranges'
I looked in ppc4xx-ebc.h and EBC_NUM_BANKS is only defined for 405xx and 440xx variants. I tried setting it to zero and it works so far (see the following diff), but is there a more proper way of disabling EBC?
Yes. I would prefer to disable using this EBC fdt blob configuration on those boards without EBC. Why don't you just don't call the weak default __ft_board_setup() function in cpu/ppc4xx/fdt.c by defining a board specific version in your board-platform code (board/board_name/board_name.c)? This way you can override the weak default function and it's not called at all.
Cheers, Stefan
