[PATCH 1/7] arm: mach-omap: Change file flags in emmc handler

[Daniel Schultz]

This handler tries to read from a file descriptor with 'write only'
flags and fails. Add read permissions for the file, so the handler can
read the partition layout.

[PATCH 3/7] arm: mach-omap: Change mountpoint of boot partitions

[Daniel Schultz]

If using EMMC and SD as bootsources, mounting the boot partition of both
devices to /boot makes trouble. Either the correct device is mounted to
/boot or a remount of /boot has to be performed.

To ensure this problem each MMCn bootsource will be mounted to his own
path in /mnt/{mmc,emmc}.

Hardcoding that one instance is eMMC while the other is a SD card slot
is not so nice.

You could use cdev_mount_default() instead of mount directly. This
function only mounts when it's not mounted already and returns the
path the device is mounted to.

[PATCH 4/7] arm: boards: phytec-som-am335x: Add automount script

[Daniel Schultz]

Each boot source is mounted to either /mnt/mmc or /mnt/emmc. To make the
not-mounted boot source available in Barebox, an automount script mounts
this device to /mnt/{mmc, emmc}, if the directory will be accessed.

I know I asked this quite some times already, but: Why not bootloader
spec? grepping for "global.bootm.image=" shows that we expect the kernel
at "/linuximage", "/zImage" or "/uImage", depending on the board.
"data=journal" is only valid for ext4 and even there is not an option
everybody wants to have.
With bootloader spec the rootfs can describe itself which kernel(s)
shall be started with which devicetrees. From barebox it's easy aswell,
only type "boot mmcx" and you're done.

With these bootscripts the first one who comes decides how the board is
intended to be used. I really don't want to have this in generic boards.
