This patch adds basic SDIO/MMC booting support to MVEBU SoC's. Since I don't know of a way to test the boot-device upon runtime, this patch hardcodes the spl_boot_device instead.
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,
