-Implementation Notes:
----------------------
-
-Due to the RAM/flash bus arbitration problem the suggested workaround
-had to be implemented. It works okay. On the downside is that you
-can't really check whether 'erase' is complete by polling flash as it
-is usually done. Instead, the flash driver simply waits for a given
-time and assumes that erase then has passed. This behaviour is
-identical to what the VxWorks driver does; also, the same timeout (6
-seconds) was chosen. Note that this timeout applies for each erase
-operation, i. e. per erased sector.
