Booting kernels 3.2 and later

[plgplg]

If anyone is having trouble booting current kernels (hangs after the uncompress) on their DreamPlug and has an "old" version of U-Boot, please try the following.

CONFIG_EMBEDDED=y
# CONFIG_ARM_PATCH_PHYS_VIRT is not set
CONFIG_PHYS_OFFSET=0x0

This works around a U-Boot issue.

This allowed be to boot a current kernel without having to re-flash U-Boot.

Thank you sir for resolving this.

Glad it has helped someone else.
I spent two evenings with a JTAG debugger and "git bisect" before I finally figured it out!

I wondered how you did it.
I notice that www.xilka.com has already adopted your change.
I have tested this on two different models of Dreamplug with 3.2.4 and it works OK.

To be fair, it is a "known" problem. It just wasn't known to me.
Once I figured out what the problem was, I found other references to it:

That's always how these things seem to work.
All I can do now is try to prevent other people hitting the same issue.
