FW: [U-Boot-Users] Accessing environment from linux?

["Callebaut, Benoît"]

I looked a bit in the /tools/env directory and the code seems pretty good (I
haven't test it yet).
My question is maybe a little off topic here but anyway.
In the standard char driver for MTD devices, I see nowhere a piece of code
doing flash identification, or even calling low level read/write functions
for the flash (eg cfi commands).
How is this done ? I don't really understand when the mtd_table is filled in
using add_mtd_device.
This function is only used in mtdpart and in the device-mapping drivers.
But I don't want to use partition and if it possible, I don't want to make a
mapping driver.

Did you bother to check the recent discussion on tyhis list? All this
has been discussed just a couple of days before.

Is there anything  wrong  with  the  existing  and  working  code  in
tools/env ?


Why did you reinvent the wheel?
