If we're going to be adding a bunch of attributes from ext_csd, why not just allow dumping the entire ext_csd in a semi-readable form? Via something like hex_dump_to_buffer. This will allow easy human an machine parsing, and be more lightweight then adding a sysfs attr for each EXT_CSD byte (of which there are a lot).
I'm basing this on the thought that the only clients of these attrbutes would either be developers or engineers involved with MMC media, or very specialized software.
Thoughts?
