I've tested it on i.MX25. > = newer flashs are using ONFI and thus some 4k flashes are not properly detected actually in barebox which may be the problem that Gabriel actually have. http://en.wikipedia.org/wiki/Open_NAND_Flash_Interface_Working_Group http://onfi.org/specifications/ I have the same requirement on an i.MX53 board (for the moment I hard coded the right values to bypass the flash detection which returned wrong results, the 4k falsh being detected as a 2k one) and plan to work on this during april but hard to say when so that may be beginiong of may.
