[U-Boot] [PATCH 1/4] Fix the NAND size overflow issue.

[U-Boot] [PATCH 1/4] Fix the NAND size overflow issue.

[Jason Jin]

When the NAND size is or large than 4G, the size will overflow,
The adjustment in this patch try to fix this.

[U-Boot] [PATCH 2/4] Make the fsl_elbc_nand driver work for both 83xx and 85xx

[Jason Jin]

This patch try to make the fsl_elbc_nand driver work for
both 83xx and 85xx boards.
Move the FMR Macros from 83xx.h to fsl_lbc.h and
redefine the elbc register structure in the driver.

      ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
According to this line I suppose, the value of nand_info[i].size
is in Bytes. So, if the NAND chip is >= 4 GiB this variable
has already been overflowed, when nand_init_chip returns.
Indeed, I didn't check the source code of the NAND driver. Am I
wrong or did you modify the driver?

Kind Regards,
Jens

Hi, Jens,
You are right, the nand_info[i].size is in Bytes. and this patch just 
can fix those chips with memory cell less than 4GBytes.
The  nand_info[i].size is widly used in u-boot, If change it to MByte, 
lots of tests need to do.

Thanks

Space after brace.

Can we put this in a header file that is shared by immap_83xx.h,
immap_85xx.h, etc., rather than duplicating it here?

Did you try building this on 83xx?  You'll get a type conflict warning
because you duplicated the struct.

Thanks.
I was trying to avoid too much changes to the code, which maybe result
in other functions
can not work. Actually, As the different immap definition, to completly
avoid the duplicating, we need to merge the lbc immap for 85xx/83xx and
change the related code.

There is already a fsl_lbc.h file in include/asm but it is included by
some .S file and can not move the structure into it. How about define a
immap_fsl_lbc.h file for the structure?

Thanks, If we still define the structure in the file, we need to change
the structure name.

You can surround it with #ifndef __ASSEMBLY__

I think the comment is misleading.

Assuming we have a single NAND device that is bigger than 4 GiB, then
the overflow would actually happen earlier, i. e.  when  storing  the
size in nand_info[].size, as nand_info[].size is an "u_int32_t".

So the only situation your patch can fix is when  there  are  several
NAND  devices,  each  of  them smaller than 4 GiB, but the total size
exceeds this limit.

Applied after changing the comment.

Thanks.

Best regards,

Wolfgang Denk
