PATCH 1/4 wandboard: Use ext4 rootfs type

From: Fabio Estevam <[email protected]>

Use ext4 rootfs type instead of ext2, as it is more reliable.

PATCH 2/4 wandboard: Use kernel version 4.7.3

From: Fabio Estevam <[email protected]>

Wandboard is well supported in the mainline kernel, so let's switch from the 3.14 vendor kernel to 4.7.3 mainline kernel version.

As mainline use more dts files to support both B1 and C1 versions of the board, adjust the dts entries accordingly.

PATCH 3/4 wandboard: Use U-Boot 2016.07

In reply to Fabio Estevam

From: Fabio Estevam <[email protected]>

Upgrade U-Boot version to 2016.07 and make proper use of U-Boot distro configuration features.

Provide a boot.scr binary script that is one of the standard ways to pass a U-Boot script with distro features enabled.

With this method the uboot-env.txt file is no longer needed, so it is removed.

PATCH 1/4 wandboard: Use ext4 rootfs type

In reply to Fabio Estevam

Hello,

From: Fabio Estevam <[email protected]>
Use ext4 rootfs type instead of ext2, as it is more reliable.
Signed-off-by Fabio Estevam <[email protected]>

This commit log is incorrect: the ext4 filesystem is already used. Indeed, the ext4 image is a symlink to the ext2 image, and the ext2 image is in fact an ext4 image:

-rw-r--r-- 1 thomas thomas 3763200 sept. 11 21:54 rootfs.ext2
lrwxrwxrwx 1 thomas thomas 11 sept. 11 21:54 rootfs.ext4 -> rootfs.ext2

So, using the .ext4 image is probably a good idea, but the commit log should reflect that.

Best regards,

Thomas
