Hi Chris,

I am just starting with uClinux. This must be a very basic question,
but I've been going round in circles.
I need to do a port to our hardware. Our board has a 5272 but it has a
different memory map from the platforms which are currently supported
(different location for ROM, RAM and I/O devices). I am having trouble
finding information of how to do it with the 2.6.x Kernel. I have the
FAQ for the 2.4.x Kernel, but it doesn't seem to apply to 2.6.x (no
rom.ld, crt0_rom/ram.s etc.).
None of those files exist in the 2.6 code base now.
Has the method to do port changed between 2.4 and 2.6?
Yes, well, the details of the exact way to make the change has.
Is there a howto for 2.6.x ports?
None as far as I know.
If not could anyone guide me through
the process?
The base RAM addresses are now all configure at kernel
configure time (that is when you do "make config").
Where are rom.ld, crt0_rom/ram.s etc. for 2.6?
They don't exist in that form.
The common head code for all ColdFire parts is now:
linux-2.6.x/arch/m68knommu/platform/5307/head.S
The common linker script for all m68knommu/ColdFire parts is:
linux-2.6.x/arch/m68knommu/kernel/vmlinux.lds.S
Regards
Greg
