[PATCH v2 05/11] mci: atmel_mci: Add PBL helper to configure highcapacity

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Older atmel SoC's like at91sam9263 do not support highcapacity SD cards.
Add helper that can be used to disable highcapacity support
in the PBL code - as probing for the SD card type is not an option.
