I am trying to boot
I have an external SD card.
I have a PERMANENT eMMC card on the board. (BROKEN_CARD_DETECT set and POLLING
OFF)
I have a PERMANENT sdio card on the board (BROKEN_CARD_DETECT set and POLLING
OFF)
I am trying to boot from the eMMC.
in the arch directory if I init the SD controller first -- booting fails
if I init the eMMC SD booting works
>From the trace so far it looks like I cannot have 2 entries on the the
>workqueue for mmc_rescan.
The sdhci driver sees 2 permanent slots and calls up to the mmc layer to handle
initial card detect.
I think the workqueue needs to check if work is pending and reschedule itself
-- not sure how to do this.
mmc_rescan is not being called -- any ideas ?
