There have been 3 versions of the sunxi_emac support patch during its development. Somehow version 2 ended up in upstream u-boot where as the u-boot-sunxi git repo got version 3.
This bumps the version in upstream u-boot to version 3 of the patch:
- Initialize MII clock earlier so mii access to allow independent use
- Name change from WEMAC to EMAC to match mainline kernel & chip manual
- Cosmetic code cleanup

Shouldn't the cosmetic and functional changes be normally split into separate patches? Indeed, it looks like the move of
/* Set MII clock */clrsetbits_le32(®s->mac_mcfg, 0xf << 2, 0xd << 2);is the only functional change in this rather large patch.
And could you please elaborate on
- Initialize MII clock earlier so mii access to allow independent use
was this causing any user visible problems?
I'm not the author if the patch, so you will need to ask Stefan. Note though that the code after this patch is the code which we've been using in the linux-sunxi-u-boot for as long as I can remember, and the code which went upstream was never enabled / used as is.
