Not sure about 6820, but for 6710 this info can be traced back from the
functional spec [1] to the device data sheet [2] as the sample-at-reset
(SAR) data, which (for the 6710 at least) is an embedded XLS sheet [3].
Maybe you can find the same info for 6820?

For 6710:

[1] "88F6710, 88F6707, and 88F6W11 ARMADA ® 370 SoC Functional
    Specifications – Unrestricted"
    Doc. No. MV-S107979-U0, Rev. B

[2] "88F6710, 88F6707, and 88F6W11 ARMADA ® 370 SoC Hardware
    Specifications"
    Doc. No. MV-S107978-00, Rev. G

[3] "Sample at Reset Table" and "Boot Source List" tabs in 
    88F6707_Pin_information.xls

Amicalement,
