Hi Clemens,
Thanks for your help. I've done it now (see attached). The
partitioning is specific to our application but it is easily modified.
I noticed a buggette in the mtd code while doing this. If you build
everything as a module then the sub-module loading doesn't work
properly. For example in gen_probe.c it says
#ifdef CONFIG_MTD_CFI_INTELEXT
case 0x0001:
case 0x0003:
return cfi_cmdset_0001(map, primary);
#endif
where it should really say
#if defined(CONFIG_MTD_CFI_INTELEXT) ||
defined(CONFIG_MTD_CFI_INTELEXT_MODULE)
case 0x0001:
case 0x0003:
return cfi_cmdset_0001(map, primary);
#endif
There are several problems like this. In the end I gave up and just
built everything except the actual mapping driver as kernel resident.
