[U-Boot] sunxi: broken sun4i_emacs, all boards?

[Artturi Alm]

Hi,

this has been 'blocking' my attempts to revive the A10-boards i have
since early june, or so.

now i found this commit abc3e4df59f54cf3dda42a35a75d617fe861f5fe, which
left the drivers/net/Makefile untouched, essentially breaking sunxi_emac.

the diff below didn't fix it however, i can see how it does arp who-has,
and the remote replying, but u-boot does act as if nothing is received back?

The patch sounds about right, can you send it please?

I guess the select PHYLIB should be properly indented, and split into
a separate commit.

Thanks!

Not sure what you mean, but if you mean proper [PATCH] w/signed-off etc.,
then no - i'm sorry but i don't even know how, and kind of wish i could
get by w/o learning how.

Yep, the whitespace error got copypasted from config SUN8I_EMAC, which
is pretty broken w/regards spaces vs tab. left untouched in diff below
w/o copypasting spaces, which you're of course free to split in as many
commits you want. :)

sunxi: sun4i emac fixes.

fixes CONFIG_SUNXI_EMAC references from drivers/net/Makefile and
include/configs/sunxi-common.h forgotten(?) in commit:
	sunxi: Convert SUNXI_EMAC to Kconfig
	abc3e4df59f54cf3dda42a35a75d617fe861f5fe

i have only three different kinds of A10 boards, but they all have
realtek phy, so i chose to combine the #ifdef in sunxi-common.h with
CONFIG_SUN7I_GMAC. admittedly it felt horrible place to default on such,
but if sun7i_gmac can, why sun4i_emac could not?

because of misnaming above, i think the need for "select PHYLIB" under
config SUN4I_EMAC was missed in commit:
	Move PHYLIB to Kconfig
