[U-Boot] sunxi configs break with CONFIG_API in v2015.10-rc4

[Andreas Färber]

Hi,

For at least Bananapi, Cubieboard, Cubieboard2, Cubietruck, Mele_A1000,
A10-OLinuXino-Lime, A13-OLinuXino, A20-OLinuXino-Lime2 and probably
other sunxi boards, enabling CONFIG_API in the distro defaults header
leads to build failures like this one:

[  105s]   CC      api/api_net.o
[  105s] api/api_net.c: In function 'dev_enum_net':
[  105s] api/api_net.c:61:35: warning: initialization from incompatible
pointer type [-Wincompatible-pointer-types]
[  105s]   struct eth_device *eth_current = eth_get_dev();
[  105s]                                    ^
[  105s] api/api_net.c:68:39: error: dereferencing pointer to incomplete
type 'struct eth_device'
[  105s]   memcpy(di->di_net.hwaddr, eth_current->enetaddr, 6);
[  105s]                                        ^
[  105s] scripts/Makefile.build:277: recipe for target 'api/api_net.o'
failed
[  105s] make[1]: *** [api/api_net.o] Error 1
[  105s] Makefile:1191: recipe for target 'api' failed
[  105s] make: *** [api] Error 2

Could you please check on why that is?

By comparison, this is working fine for jetson-tk1; arndale, snow and
possibly others are lacking a define for the maximum number of MMCs
(preparing a patch).

Thanks,
Andreas
