[Buildroot] [PATCH 0/2] cubieboard: new set of patches for mainline kernel

[Carlo Caione]

Hi,
the following two patches are again for cubieboard but using the mainline
kernel and limiting as much as possible the usage of tools from
sunxi-repository.

  cubieboard: defconfig for mainline kernel

[Buildroot] [PATCH 1/2] cubieboard: defconfig for mainline kernel

[Carlo Caione]

This is a new defconfig supporting the cubieboard. Differently from the
previous defconfig (cubieboard_defconfig) using kernel and tools directly
taken from the linux-sunxi repository, this defconfig uses the mainline kernel
that already partially supports the board.
The only sunxi-specific package is sunxi-uboot that will be replaced as soon
as a mainline version is released.

[Buildroot] [PATCH 2/2] cubieboard: board specific files and script

[Carlo Caione]

This set of files contains:
 - readme.txt
 - mksdcard.sh: scritp to create the SD card for cubieboard
 - uEnv*.txt: different uEnv for u-boot (to boot using TFTP or using the SD
   card to host uImage and DTB)

+Cubieboard - mainline kernel
+
+-----
+Intro
+-----
+
+This is the buildroot board support for the Cubieboard using the mainline
+kernel.
+
+---------------
+How to build it
+---------------
+
+You need to use the cubieboard_mainline_defconfig, to do so:
+ * make cubieboard_mainline_defconfig
+
+And to compile:
+ * make
+
+-----------------
+What is generated
+-----------------
+
+After building, you should have this tree:
+
+    output/images/
+    +-- ...
+    +-- sun4i-a10-cubieboard.dtb
+    +-- sunxi-spl.bin
+    +-- u-boot.bin
+    `-- uImage
+
+-----------
+How to boot 
+-----------
+
+To boot the cubieboard with the file generated by buildroot you have to
+choices:
+
+- using TFTP to load uImage and DTB
+- load uImage and DTB on the SD card
+
+In both cases you need a SD card to host u-boot, SPL and uEnv.txt
+
+In case you choose to boot using TFTP, be sure to modify the file
+uEnv-tftp.txt with the correct parameters for your network.
+
+--------------------------
+How setting up the SD card
+--------------------------
+
+To be able to use your cubieboard board with the images generated by
+Buildroot you have to correctly setup the SD card.
+
+For more information, please see http://linux-sunxi.org/FirstSteps
+
+Depending on the rootfs size, you might want to use a 2GB or larger SD-card.
+The script mksdcard.sh will take care of partitioning and formatting
+the SD-card.
+
+BEWARE! This process will erase your SD card.
+
+Use dmesg to find out where the SD card is attached in the /dev tree
+(<device>) and then:
+
+# sudo./mksdcard.sh <images_dir> <uEnv> <drive>
+
+where:
+ - <images_dir> is the directory containing the generated files (usually
+   output/images)
+ - <device> is the device file of the SD card (usually /dev/sdX)
+ - <uEnv> can be: 
+ 	- uEnv-tftp.txt to boot over TFTP
+	- uEnv.txt to boot using files on SD

[Buildroot] [PATCH 1/2] cubieboard: defconfig for mainline kernel

You should specify a version for the Linux kernel. Otherwise, it will
automatically get bumped to the latest version, which is not what we
want for our defconfig: we want them to build a well-known version of
the various components such as the kernel, U-Boot, etc.
