Hi
We have a product on the Freescale imx28 booting from a NAND Flash.
Lately we have seen high numbers of boards failing, and find we have received
batches with marked bad blocks in lower boot addresses of Flash.
Typically we see bad blocks in partition where Barebox are located.
We do also us
Erasing the whole flash takes approximately 7s on one of my test
machines. Expand the timeout accordingly.
Note however that it is in general not allowed to hold the flash
semaphore for so long and "firmware might implement a timeout
mechanism and take ownership of the relevant [lock]" after one s
The shadow RAM that is used to serve read requests from the eeprom
interface isn't valid in all cases. Catch these by returning an error in
the eeprom read function and make eeprom validation dependant on
working access.

There used to be four places that all emit the same error message. Even
if in a given context not all four of them can be relevant, there are
always two possible locations where the message can origin from.
So make the output slightly different in all places to ease future
debugging.

When the flash doesn't hold a valid firmware image there are still
some things (like accessing the flash) possible. Don't return an error
code in this case but return 0 instead. This way the driver is
regularily bound and just doesn't provide a network interface.

As a convenience for users of globalvar_add_simple_string() create an
empty value for the variable when passed a NULL pointer as value.

nv variables in the form dev..* can be used to make device
parameters persistent. Add these to the completion list to make setting
these variables more convenient.
