What are these values: NPP_BOARD_INTERNAL_SRAM_BASE,
NPP_BOARD_INTERNAL_SRAM_END and NPP_BOARD_INTERNAL_SRAM_BASE.
Also, what is ENTRYLO() defined as?

This may or may not apply to your case. Is this board still the one
that has the Marvell Discovery ethernet device? If yes, Marvell
Discovery has its SRAM located at 0xfe000000. So, make a check in the
ethernet driver or other board specific sources and see if there is
any access to this SRAM location.
The DMA buffers and DMA buffer descriptors used for the serial driver
are all located in the SRAM of the Marvell, which is mapped using a
wired uncached TLB entry.
Here's the code that wires the entry :
I would like to use ioremap() instead of wired TLB entries, but for the
moment, I'm focusing on this crash.
