All publicly available datasheets for Marvell ARM SoCs are referenced
in Documentation/arm/Marvell/README.
See for example
http://www.marvell.com/embedded-processors/kirkwood/assets/HW_88F6281_OpenSource.pdf,
which is the hardware datasheet for the 88F6281 Marvell SoC (Kirkwood
family). Table 26 on page 53 of the PDF is a good example. It lists all
the pins, on per row, and then has columns for each function identifier
(from 0x0 to 0x7). Then each cell says when pin X is muxed in function
Y, it provides this functionality.
So clearly, this representation is a list of pins, and for each pin, a
list of possible functions that this pin can take.
Best regards,
Thomas
