How can I download these patches?

No idea if this can be automated. They are pretty old now anyway and probably would not apply cleanly. Best is probably to browse the mailing list archive and manually extract and apply the relevant code.
Quite frankly not sure this is worth the effort if one has worked on H3 mainline support since then, you'll end up with what I described above, 1 core running way below max cpu freq, no networking.

I am also working (slowly) on the mainline kernel.
A first patch on the kernel 4.2 from Jens did boot with one CPU at slow speed and the UART.
I update Jens's patch for the kernel 4.3, but I should have done some error: the kernel does not boot and there is no trace because no UART!
Anyway, I uploaded this patch on my site - see http://moinejf.free.fr/opi2/.

Pratically, I build the kernel on my OPI2 (kernel 3.4) with gcc-5.2.1. At the end of generation (including the copy of the .dts at the end of the kernel), as root, I just copy the uImage to the first partition of the SDcard (with a name different of the 3.4) and install the modules.
To test the kernel, I reboot, stopping the automatic start in the U-boot, and replacing the 'uImage' name in the 'boot_normal' variable.

Otherwise, I tried to write a rtl8189es driver starting from the 8188ee, but I have only a few knowledge about SDIO, so,
I am writing a DRM video driver...

Your patch (http://moinejf.free.fr/opi2/kernel-3.4.patch) fix HDMI audio.So, you touched "HDMI files", could you try to add support form HDMI CEC ?

It it possible to use for exmaple these files:

Hi All,
I've had some success this evening booting the latest u-boot and the linux-next kernel with the patches that jemk has just pushed. I'll put some instructions together tomorrow morning if anybody wants them. There is still loads to do but this a massive step in the right direction.

There is a long road to go, but probably the only one who is worth.
It makes me a little angry that allwinner does absolutely nothing to support this effort.

@codekipper:

Thank you!  I'll let you know how it goes....

@Codekipper

Could I get your build technique?  Thanks!

@fritz - I'm certain Allwinner's business strategy is selling chipsets for the Android platform which is still stuck in the 3.blah kernel era. Mainlining is a time consuming business and considering that they're a small company unlikely to high up on their agenda. I use to work for a SoC vendor with 5 times the number of staff as AW and we struggled with both mainlining and selling chipsets. When a customer started requiring more attention then those resources working on mainlining were shipped to other areas. Most people just want cheap hardware. On the other hand it give us something to do in the community.

@faddat - I'm currently putting something together....you can get ahead by syncing the linux-next kernel git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next and these u-boot repos https://github.com/jwrdegoede/u-boot-sunxi and https://github.com/jemk/u-boot-sunxi.git. If you could apply these patches to the kernel then you're most of the way there

Here are some more detailed instructions.
I'm always try to work with pretty much the latest u-boot and kernel. There may be some errors here as I use scripts for a lot of my building and setup. Most of below has been taken from my bash history.

Prepare your card

(echo n; echo p; echo 1; echo 2048; echo +15M; echo n; echo p; echo 2; echo 32768; echo +240M; echo p; echo w) | fdisk /dev/<CARD_LOCATION>
mkfs.vfat /dev/<CARD_LOCATION>1

Build u-boot

In your u-boot git have the following remotes.
git remote add jemk https://github.com/jemk/u-boot-sunxi.git (this is where the patches are)
git remote add sunxi-wip https://github.com/jwrdegoede/u-boot-sunxi (Hans' development track for u-boot)
git fetch --all
git branch orangepi sunxi-wip/sunxi-wip (creates new branch at the latest commit from Hans)
git checkout orangepi
git cherry-pick jemk/sunxi/h3~4..jemk/sunxi/h3 (this adds jemk's h3 patches to the latest u-boot)
make ARCH=arm -j 18 CROSS_COMPILE=arm-linux-gnueabihf- xunlong_orangepi_plus_defconfig
make ARCH=arm -j 18 CROSS_COMPILE=arm-linux-gnueabihf-
dd if=u-boot-sunxi-with-spl.bin of=/dev/<CARD_LOCATION> bs=1024 seek=8
sync
At this point the card should boot to u-boot prompt

Build kernel

In your kernel git have the following remote.
git remote add linux-next git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next
git fetch --all
git branch orangepi linux-next/master

This should now boot to the openwrt prompt.
