[U-Boot] [PATCH v5 0/8] sunxi: initial upstreaming effort

[Ian Campbell]

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

+==Minor changes in v5

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.

This series can also be found at:

    git://gitorious.org/ijc/u-boot.git sunxi-mainlining-v5

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).
