[Buildroot] [PATCH 0/5] A20-OLinuXino-Lime: new board

[Francois Perrad]

This set adds the board A20-OLinuXino-Lime, with 2 flavors:
    - kernel mainline + uboot mainline
    - linux-sunxi (3.4.x) + uboot-sunxi

And also updates two sunxi related packages (sunxi-board & a10disp).

Francois Perrad (5):
  sunxi-board: bump to version a6a4e94066f4ec6b26fc7060dc453a6bcf26a504
  a10disp: bump to version v0.6.1
  A20-OLinuXino-Lime: new board (mainline)
  cubieboard: rename script to mksunxicard.sh
  A20-OLinuXino-Lime: new board (legacy)

+
+Intro
+=====
+
+This is a open hardware board,
+see https://www.olimex.com/Products/OLinuXino/open-source-hardware
+
+See https://linux-sunxi.org/Linux_Kernel, for choosing between
+the legacy linux-sunxi kernel and the device tree / mainline kernel.
+
+
+How to build it
+===============
+
+    $ make olimex_a20_olinuxino_defconfig
+
+Compile all and build rootfs image:
+
+    $ make
+
+Result of the build
+-------------------
+
+After building, you should get a tree like this:
+
+    output/images/
+    +-- rootfs.ext2
+    +-- sun7i-a20-olinuxino-lime.dtb
+    +-- u-boot.bin

+    `-- zImage
+
+
+How setting up the SD card
+==========================
+
+
+Prepare the SD card
+-------------------
+
+Erase existing stuff, and create an unique Linux partition with `fdisk`.
+
+    # fdisk /dev/sdX
+    Command (m for help): o

+    After that, of course, the previous content won't be recoverable.
+
+    Command (m for help): n
+    Partition type:
+        p   primary (0 primary, 0 extended, 4 free)

+    Using default value 7626751

+    4 heads, 16 sectors/track, 119168 cylinders, total 7626752 sectors
+    Units = sectors of 1 * 512 = 512 bytes
+    Sector size (logical/physical): 512 bytes / 512 bytes
+    I/O size (minimum/optimal): 512 bytes / 512 bytes

+    Command (m for help): w
+    The partition table has been altered!
+
+    Calling ioctl() to re-read partition table.
+    Syncing disks.
+
+Copy images on the SD card
+--------------------------
+
+    # dd if=output/images/rootfs.ext2 of=/dev/sdX1 bs=512
+    # dd if=output/images/u-boot-sunxi-with-spl.bin of=/dev/sdX bs=1024 seek=8
+
+
+Finish
+======
+
+Eject the SD card, insert it in the A20-OLinuXino-LIME board, and power it up.

+
+Use `dmesg` to find out where the SD card is attached in the /dev tree
+(<device>) and then:

+
+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)
+

+
+Eject the SD card, insert it in the A20-OLinuXino-LIME board, and pwer it up.

 If you set BR2_LINUX_KERNEL_INSTALL_TARGET=y, buildroot will install the dtb(s)
and the kernel in /boot. It will not use a dtb directory but that's not really
needed, right?

 So actually, this is the only part of the script that is really needed.

 Perhaps we could add an option in boot/uboot to do this from buildroot as well.

 bs is not needed here (it just slows thing down).

 Please also use a custom kernel headers version (4.1 will be the default soon...).

 and use SAME_AS_HEADERS here.

 As mentioned above, use BR2_LINUX_KERNEL_INSTALL_TARGET

 I think we should start using BR2_TARGET_ROOTFS_EXT2_4 where possible. A few of
our defconfigs have it already but it should be generalized IMHO.

[Buildroot] [PATCH 5/5] A20-OLinuXino-Lime: new board (legacy)

 Instead of legacy, I'd call it 3d or accelerated or something, that makes the
difference a little clearer.

 Since this is anyway a symlink, there's no need to rename the script in patch
4/5, you can just link to mkcubiecard.sh.

 If you follow the comments I made in patch 3/5, you can rewrite this to pass
the input .cmd and output directory as a parameter to the script. So

$MKIMAGE -A arm -O linux -T script -C none -d $2 $3/boot.scr

BR2_ROOTFS_POST_SCRIPT_ARGS="board/.../boot-legacy.cmd $(BINARIES_DIR)"

and for the mainline one:

BR2_ROOTFS_POST_SCRIPT_ARGS="board/.../boot.cmd $(TARGET_DIR)/boot"

 I would combine both versions in a single readme.txt.

 I think you should copy the TL;DR in this file:

The legacy linux-sunxi kernels are based on the vendor code drops. It is only
useful when accelerated 3D graphics and multimedia support is strictly necessary.

The Mainline Kernel is already a much better choice for a headless server. And
also the mainline kernel works fine even for a basic Linux desktop system
running on top of a simple framebuffer, which may be good enough for the users
who do not need fancy 3D graphics or video playback acceleration.

 Of course, you could just as well use the same approach for the mainline
version, i.e. put the boot stuff in a fatfs and only the real rootfs in the ext2.

 You can use a wget URL instead:
