Re: [U-Boot] [U-Boot,04/15] bootstage: Convert to use malloc()

At present bootstage uses the data section of the image to store its information. There are a few problems with this:

• It does not work on all boards (e.g. those which run from flash before

relocation)

• Allocated strings still point back to the pre-relocation data after

relocation

Now that U-Boot has a pre-relocation malloc() we can use this instead, with a pointer to the data in global_data. Update bootstage to do this and set up an init routine to allocate the memory.

Now that we have a real init function, we can drop the fake 'reset' record and add a normal one instead.

Note that part of the problem with allocated strings remains. They are reallocated but this will only work where pre-relocation memory is accessible after relocation.

Applied to u-boot/master, thanks!
