Hi, 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} Thanks Abhishek 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.
