Please note that I recently introduced a CFG_MEM_TOP_HIDE option for the 440EPx CHIP 11 errata. I suggest you take a look at this too and see if this changes your behavior.
Explain this a bit more please? Is a kernel change needed here?
This depends. When the bootwrapper version is used then yes, the kernel should get changed. This is because the bootwrapper detects the SDRAM size from the DDR2 controller and passes it to Linux.
Without bootwrapper no changes are needed, since U-Boot already passes the corrected memory size to Linux (totalsize-4k currently).
Hm. Given that AMCC ships the boards with an older U-Boot that requires cuImages, I think we'll need to patch the wrapper. Does 440GRx share this same errata? I would think so.
