Block device APIs are a much-worked-on problem, as are generic device interfaces. The special needs of firmware make them tricky. I prefer generic because it's too easy to work out a block device interface that won't fit into a generic framework -- that's been done, frequently -- but a well designed generic framework will easily accommodate a block device interface -- see Unix or Plan 9. In other words, you can design a special case that makes doing a good design of the general case almost impossible. That's been done too; see UEFI. ron
