This is my fifth attempt at an upstreamable series based upon the https://github.com/linux-sunxi/u-boot-sunxi.git#sunxi tree. The intention is to present a minimal starting point for upstreaming to which support for other processors, peripherals, boards etc can be added in the future. Therefore this has been stripped right back and currently supports only sun7i processors (AKA Allwinner A20) and the cubietruck board. Supported peripherals are UART, MMC and Ethernet.
The code here is from u-boot-sunxi.git#sunxi[0] changeset based on d9fe0a1e061e 3f5ff92b1503 "sunxi: add comments to pll1_para array." and applies to u-boot v2014.04. It merges cleanly into current mainline head.
As of v4 the majority of the series now has at least one Ack or Reviewed-by. In summary:
+ sunxi: add sun7i clocks and timer support. mT sunxi: add sun7i pinmux and gpio support M sunxi: add sun7i dram setup support M + sunxi: add sun7i cpu, board and start of day support MT sunxi: add support for Cubietruck booting in FEL mode M sunxi: add gmac Ethernet support M sunxi: mmc support M sunxi: non-FEL SPL boot support for sun7i

Changes in v5: - Resynced with u-boot-sunxi.git 3f5ff92b1503 "sunxi: add comments to pll1_para array.". Dropped "Reduce DMA burst length" patch which is being handled elsewhere. Otherwise see individual commit logs for details.
Changes in v4: - Resynced with u-boot-sunxi.git d9fe0a1e061e which pulled lots of fixes for Marek's review comments.
Global changes in v3: - Rebased onto v2014.04 and resynced with u-boot-sunxi.git c89867dca2e9 - Improved commit messages - Updated lists of contributors - Added some CCs - Lots of cleanup based on review comments.
Global changes in v2: - Use SPDX-License-Identifier - Resync with u-boot-sunxi.git - Lot of updates to the individual patches, see the individual commit messages (checkpatch.pl fixes, magic number removal etc). - Pulled the Ethernet stuff before the MMC and non-FEL boot stuff. The MMC stuff (which non-FEL boot needs) still needs some more cleanup, but the reordering means that the initial part of the series could in principal go in.

There is no SMP here, since that relies on the PSCI support from Marc Zyngier which has yet to land in mainline. Marc has recently rebased and a version based on this series can be found at:
git://gitorious.org/ijc/u-boot.git sunxi-mainlining-v5-smp
I've tried to give corect credit and S-o-b based upon: git log --pretty='%aN' linux-sunxi/sunxi -- [PATHS] | sort -u git log linux-sunxi/sunxi -- [PATHS] | grep -i signed.off.by | sort -u Manual inspection
This will tend to over credit, since it will include folks who contributed code which has since been removed as well as those who contributed code which is not included in this patch set, but I think it is better to be conservative and include too many rather than incorrectly exclude people. Doing better than this would be IMHO too hard to be worth it (e.g. git blame would prefer a recent whitespace cleanup to the actual author of the code and prefer someone did code motion over the original author, so it would be a massive & manual process).
