This is really really small, and precludes using UBI on NAND for example.
What is a suitable value? I see a lots of boards using 128kB or <1MB and only a handful using more. Tegra uses 4MB -- is that a reasonable value?
4MB is reasonable when you start having to worry about 4KB page NAND and UBI. I might have been a little harsh saying "really really small" and 1MB might be just enough to work with smaller page size NAND.
Thanks, I'll go with 4MB then.
Ian.
