NAK.

Patch doesn't work. After applying I get the following messages on Kilauea:

=> nand write 100000 0 100000

NAND write: device 0 offset 0x0, size 0x0
 0 bytes written: OK
=> nand read 200000 0 100000

NAND read: device 0 offset 0x0, size 0x0
 0 bytes read: OK

So nothing is read/written at all. This is how it behaves without this patch:

=> nand write 100000 0 100000

NAND write: device 0 offset 0x0, size 0x100000
 1048576 bytes written: OK
=> nand read 200000 0 100000

NAND read: device 0 offset 0x0, size 0x100000
 1048576 bytes read: OK

I think this is plain wrong. It may silence the warning, but it is
wrong.

The type is the result of calling simple_strtoul(), and this function
returns, um, and unsigned long. And not an offset type.

No. That's all wrong.


NAK.

I disagree, the true type of the offest is loff_t and size is size_t in
the linux/mtd.

Maybe we need to do the cast to ulong in this function.

We discussed this before.

string-to-long converts into a "long" type, not into an offset type.

I think this is actually not the right fix.

To make things right, both rtc_set() and rtc_get() should return
"int".

Yes, I'm aware that this is far beyond the scope of your fixes here,
but I wanted to at least note that.

Note that this is no NAK.

The word "fit", as I understand it, means "appropriate to a purpose",
and I would say the body of the Dean is supremely appropriate to  the

I did this too, but did not do as good a job (I did not change SOBJS to 
SOBJS-y and START to START-y).  Reference for my version:
   <http://article.gmane.org/gmane.comp.boot-loaders.u-boot/38885/>

I've replaced my version with J-C's version in u-boot-fdt.

P.S. Thanks, Jean-Christophe, for doing a bunch of warning clean up.

I cannot see any correlation between your commit message and the
actual changes???

Actually, I've already slipped this one in through the u-boot-fdt 
repository (I took the liberty since it was a problem with fdt.o and 
CONFIG_OF_LIBFDT).

<http://article.gmane.org/gmane.comp.boot-loaders.u-boot/39261/>

The problem is that only a couple of 8xx boards are using libfdt, but 
they were *all* compiling fdt.c.  The result for the boards that did not 
have CONFIG_OF_LIBFDT was the compilation warnings on the (erroneously 
compiled) fdt.c.

I had fixed it independently, but Jean-Christophe's fix was better (more 
complete), so I dropped my patch and picked up his.
