[PATCH 1/5] qla2xxx: Correct Atmel flash-part handling.

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

 



From: Lalit Chandivade <lalit.chandivade@xxxxxxxxxx>

Use correct block size (4K) for erase command 0x20 for Atmel
Flash. Use dword addresses for determining sector boundary.
