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

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.

Some time ago (a year?) I downloaded SELF and found some busybox
applets for
manipulating the environment variables. Recently I have been looking to
find
perhaps a more recent version, but I had the impression it was no
longer
included. Why, I thought it is a clean solution?

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

I am using the "redundant environment variables" feature and adapted
the
busybox applets I found before. It works fine but there was no real
clean
way to introduce the feature in the existing code and it should be
reworked.
Anybody interested?

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


Why did you reinvent the wheel?
