Hi all,
     Its the bootflash that is mapped at ff800000 so I think i have not much
option but to move PKMAP_BASE which i tried at fc000000 but with no luck .

what could be wrong..

   thanks a lot , a spot on solution.. {Should have checked the list...}
that's indeed the case here, with one of the code lines.

   "io_block_mapping(0xff800000, 0xff800000, 0x00800000, _PAGE_IO);"
I will  check with this modified to appropriate value {I don't have hardware
right now}

Just one question , will this even effect when the kernel is compiled with
no CONFIG_HIGHMEM option? Thats the image I first tried and it hung ...{When
I was expecting it to come up with 768 MB of Memory}


Hi ,
  Are u having a call to io_block_mapping () in ur
arch/ppc/platfrom/<board_setup.c> covering the PKMAP_BASE ( 0xfe000000) when

using a kernel configured with CONFIG_HIGHMEM ?
The io_block_mapping will be used by you to get the early serial messages on

the console.
