This changeset, notably omap24xx_i2c.c, breaks (ARM-only?) non-omap24xx 
builds.  The attached patch relocates the omap24xx-specific i2c header 
information from asm-arm/arch-arm1136/i2c.h to include/omap24xx_i2c.h.

Patch was generated against current CVS sources.

Thanks, Cory.  It currently breaks PowerPC builds too.

Sorry,

I ran into the build problem long ago and fixed it locally.  I was
preparing to resubmit a patch with a lot of additions and this one
fix....as I was thinking Wolfgang had bypassed it.

I believe the real fix I used was in the driver itself not above.  Its
much simpler and I think the correct one.

Regards,
Richard W.



The File drivers/omap2420_i2c.c needs to look like this:
-----------------------------------------------------------
#include <common.h>

#ifdef CONFIG_DRIVER_OMAP24XX_I2C

#include <asm/arch/i2c.h>
#include <asm/io.h>

#define inw(a) __raw_readw(a)
#define outw(a,v) __raw_writew(a,v)


-----------------------------------------------------------

previously it WRONGLY looked like:

#include <common.h>
#include <asm/arch/i2c.h>
#include <asm/io.h>

#define inw(a) __raw_readw(a)
#define outw(a,v) __raw_writew(a,v)

#ifdef CONFIG_DRIVER_OMAP24XX_I2C

Agreed.  After a bit more testing, I found that there were preprocessor 
warnings generated due to symbols being defined multiple times between 
your i2c.h and the omap1510.h (notably inb(), outb() and the like).  I 
came up with pretty much the same solution as you, and am running a 
MAKEALL test now just to be sure there are no issues this time. 
Assuming not, I'll re-send just the above changes as a patch to resolve 
this.

Thanks.

-Cory

Attached is a patch which simply includes the above fix.  This time, 
there were no other issues raised during a "MAKEALL arm" test.

Wolfgang, please apply this in lieu of the previous patch, as it's the 
simpler fix.

Thanks.
