[U-Boot] how big is the NOR flash on 85xx boards?

I was wondering if we can see how big the NOR flash is on the XES &  
TQM boards.

thanks.

XES's 85xx and 86xx boards should all have U-Boot located in a NOR flash
that is either 64MB or 128MB.  Sector sizes are generally 128KB.

Out of curiosity, how does XES and TQM's flash size affect what
Freescale does for its reference platforms?  XES's preference would be
to maintain the current 512KB size to maintain continuity with
documentation, programming scripts, fdts, etc.

Would it be possible to trim down some of the enabled config options in
the larger Freescale boards?  The XPedite5370 (mpc8572-based board) has
quite a few features enabled, and it has a lot of room to spare:

   text	   data	    bss	    dec	    hex	filename
 307948	  26920	  37384	 372252	  5ae1c	u-boot

Best,
Peter

Dear Kumar Gala,

Including the old MPC8xx? They usually have 4 or 8 MB NOR.

Anything else usually has 32...128 MB.

If I remember correctly, there are configurations of the TQM8548 with
4 GB NOR flash - no kidding.

Why do you ask?

Best regards,

Do you suppose the reason the ends of the `Intel Inside'  logo  don't
match up is that it was drawn on a Pentium?

I'm asking this just see if we bump up in size if it should be to 768k  
or 1M.  While this doesn't directly impact the TQM or XES boards I  
just wanted to get a sense of how much flash people are putting on  
boards today to see if 1M is a burden or in the noise w/regards to the  
size of things.

My desire is if we support a different size on 8536DS that its a size  
other boards would be ok with if they needed to grow.

So far we have many systems that are well below 256 kB.  512  kB  al-
ready seems to a a LOT for just a boot loader. Yes, features like UBI
and  graphics support cost a price, but these are still non-standard,
right?

I think this is only a Freescale internal issue.

And thus my desire is to just disable BEDBUG as its not something we  
really use and its anywhere near correct for e500.  I'm not even sure  
how it got enabled.  Its also a little weird in that its enabled based  
on having PCI enabled:

#if defined(CONFIG_PCI)
     #define CONFIG_CMD_PCI
     #define CONFIG_CMD_BEDBUG
     #define CONFIG_CMD_NET
     #define CONFIG_CMD_SCSI
     #define CONFIG_CMD_EXT2
#endif
