Thread-topic: Init not working in 64-bit kernel
Hi,
        I'm sry.  I couldn't reply immediately.
I've fixed the problem. U'r suggestion was valuable. I've signed
extended the addresses required and I'm able to boot the board.

Thanking u.

Regards,
Vadi.

I suppose he is trying 64bit kernel on RBTX4938 board, but the board
dependent code seems not ready for 64bit.  For example, there are some
0xff1fXXXX constants there and all these constants must be sign extended
(0xffffffffff1fXXXX) for 64bit.  Also these virtual address are mapped
to 36bit physical address 0xfff1fXXXX so some assumption in the 32bit
kernel (virt==phys for TX49 internal regs) is not true in 64bit kernel.
