wdenk	a6db71d	2003-04-08 23:25:21 +0000	[diff] [blame]	74	Implementation Notes:
				75	---------------------
				76
				77	Due to the RAM/flash bus arbitration problem the suggested workaround
				78	had to be implemented. It works okay. On the downside is that you
				79	can't really check whether 'erase' is complete by polling flash as it
				80	is usually done. Instead, the flash driver simply waits for a given
				81	time and assumes that erase then has passed. This behaviour is
				82	identical to what the VxWorks driver does; also, the same timeout (6
wdenk	57c58b4	2003-05-12 09:51:00 +0000	[diff] [blame]	83	seconds) was chosen. Note that this timeout applies for each erase
wdenk	a6db71d	2003-04-08 23:25:21 +0000	[diff] [blame]	84	operation, i. e. per erased sector.
