I am trying to port a 2.4.x kernel to a PPC750 board with a 107 controller. The board has a serial port connected to one of the ROM select lines (at 0x7C000000) and I would like to use this as my console port. So far I can boot the board and see (via the serial port) the kernel load addresses etc, and the kernel gets decompressed and starts to run. This is all fine as the MMU is off at this point. However, when the serial_console_setup() code starts trying to configure the serial port again, I get a kernel panic as I am accessing an invalid mem space (MMU now on!). How do I map this correctly??? My build is based on the sandpoint but with all the init stuff for devices, such as the RTC, removed. So I have the "standard" mapping in the MMU_init code.
