I have one basic question about the architecture files in Linux kernels. We have a board with Samsung S3C2510A MCU (ARM940T core) which is a no-mmu based CPU. I heard that "there was not a lot of ARM no-mmu support at the moment" from Ben Dooks.
The core is there, but there is very little specific machine support. The one I use for testing is non-MMU ARM is the Atmel/AT91X40 (that is CONFIG_ARCH_AT91X40). I don't run it on real hardware, but on the SkyEye emulator.
So, I started developing the architecture files for my Samsung S3C2510A MCU (ARM940T core) by looking at the existing S3C2410A (ARM920 core) architecture files. Is this my porting (developing the architecture files) correct?
Would make sense to start on something similar, yes.
How can I port the Linux on to my board which has a Samsung S3C2510A MCU (ARM940T core) which is a NO-MMU based CPU? Thanks for your suggestions / hints / comments.
You can look at what I did with the AT91X40 for an example. Or look at the patches that Ithamar Adema sent to the ARM linux mailing list in the last few days for supporting the NXP LPC2K family as another example (they are also non-MMU parts).
