Interesting. I've tried to use your patch but still hanging board_init_f. Even putting BOOKE_PAGESZ_256M in set_tlb the problem occur.

The tlb settings looks fine (debbug in setup_ddr_tlbs()):
ram_tlb_address: 0x0, ram_tlb_address: 0x0, ram_tlb_index: 0x8, tlb_size:
0xa
ram_tlb_address: 0x40000000, ram_tlb_address: 0x40000000, ram_tlb_index:

"tlb_size: 0xa" is _not_ fine.
Quoting the 8540 reference manual:
"Translation size. Defines the TLB entry page size. For arrays that contain fixed-size TLB entries, TSIZE is ignored. For variable page size arrays, the page size is 4^TSIZE Kbytes. Note that although the Freescale Semiconductor Book E standard supports all 16 page sizes defined in Book E, the e500 supports only the following: 0001 4 Kbyte 0010 16 Kbyte 0011 64 Kbyte 0100 256 Kbyte 0101 1 Mbyte 0110 4 Mbyte 0111 16 Mbyte 1000 64 Mbyte 1001 256 Mbyte"
See my patch for this in "PATCH: bugfix for reading maximum TLB size on mpc85xx"
