Sometimes execution of a function has to be delayed, for example
when a backlight can only be turned on when the picture has stabilized.
To help in such situations add a convenience function around the poller
stuff to call a function after a delay.

Before we jump to SDRAM where we just copied our code we have to

Do not call mtd_ioctl for mtdraw devices. mtd_ioctl will derefence
the priv pointer to a struct mtd_info whereas with mtdraw devices it will be
a struct mtdraw pointer. We do not need ioctls for mtdraw devices, so drop
it instead of fixing it.

A chdir to a path registered as an automount path followed by a 'ls'
results in an endless loop. This happens because the command the
automounter executes results in another automount request.
Fix this by running the automounter from the chdir code before
the cwd is actually changed.

We want to check whether boarddata contains a valid dtb if it's inside
valid memory. This includes the base of SDRAM, so use '>=' instead of '>'.

| ARM: omap4: Use writel where appropriate

| Instead of making a pure 32bit write to a read/modify/write

With this we can do 'boot <name>' where name is one of:
- a filename under /env/boot/
- a full path to a boot script
- a device name
- a partition name under /dev/
- a full path to a directory which
- contains boot scripts, or
- contains a loader/entries/ directory containing bootspec entries
Multiple names can be given, they are tried in order. So any mixture
between bootspec entries and bootscripts can be given. bootspec entries
can now also be given as a path to a directory containing bootspec entries.
