Support for sunxi-based ARM systems in d-i
Hello,
I am currently working on better support for sunxi-based ARM systems
in d-i and flash-kernel. Thanks to Ian's backport of the sunxi AHCI
support from kernel 3.15rc1 into the Debian 3.14 kernel package (as
of linux-image-3.14-trunk-armmp_3.14.1-1~exp2_armhf.deb, currently
only available as source in git) it is now possible to run d-i on
Allwinner A10/A20-based systems like the Cubie{board,board2,truck}.
I have installed Jessie on a Cubietruck today with a local build
of d-i and the installation works mostly ok. Open points are:
- A few missing kernel drivers (RTC, USB, MMC)
I have filed a wishlist bug (#745972) against the linux package
to have the missing drivers enabled in future releases.
- Missing flash-kernel support for the Cubietruck to make the
system bootable.
- No bootable uImages suitable for sunxi devices are generated
by the d-i build scripts.
I have been working on the last two points and would like to ask
whether there are any objections against committing the following
patches to the flash-kernel and installer repositories.
Flash-Kernel:

The bootscr.sunxi is written for and tested to work with u-boot-sunxi,
as getting sunxi support into the mainline u-boot codebase is still
work in progress. I'll run tests with mainline u-boot as soon as
the sunxi patches have been accepted upstream.

This generates uImage/uInitrd with a proper load address for booting
on sunxi-based systems.
