The DMA code in sunxi_mmc.c is broken. mmc_trans_data_by_dma() allocates the dma descriptors on the stack, and then exits while the dma transfer is in progress, so the dma engine is reading stack memory which at that point may be re-used. So far we've gotten away with this by luck, but recent u-boot changes have shifted the stack start address by 16 bytes, which combined with dma alignment now exposes this problem.

Since we end up just busy waiting for the dma engine anyway, this commit fixes things by simply removing the dma code, resulting in smaller bug-free code.

Add support for the x-powers axp209 pmic which is found on most A10, A13 and A20 boards.

While changing the boards.cfg lines for the Cubietruck, add myself as board maintainer for the Cubietruck.

From: Stefan Roese sr@denx.de

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

Many A20 boards (ie Cubieboard2, A20-OLinuXino_MICRO) use an 100 Mbit MII phy together with the GMAC nic found in the A20 SoC, add support for this (this will get used when we add these boards in a later patch).
