My company is designing a new piece of hardware based on a PPC. We are looking at M-Systems for storage. So how good is the Linux support for DiskOnChip?
Our options are:
1) They provide a TFFS-driver but there huge problems with license (it isn't GPL). The only way to use it is to use it as a loadable module. This is technically complicated as the root file system has to be on the DiskOnChip, so I need some kind of trick to load the module from a ramdisk or something before that.
But as far as I can see it we will still be destributing the driver along with the kernel, not linked, but residing on the same bootrom. Chouldn't that be considered as a derivative work as a whole and thus breaking the GPL?
2) We can skip M-system's TFFS and jump to JFFS2. But how stable is that on DiskOnChip? As far as I could see from the website there are still problems with bad blocks support. How does that affect the stability? What is your experience?
Is it stable enough for production use?
