Seems that this wasn't applied because Tony mentioned that this should 
not be needed any longer:

http://linux.omap.com/pipermail/linux-omap-open-source/2007-October/011525.html

I didn't check this that time. But checking today, it is still broken. 
Reproducable by using omap_osk_5912_defconfig with additional MMC 
enabled. So right, anything like this should be applied.

Cheers

Dirk

Re: [PATCH] include/asm-arm/arch-omap/omap24xx.h

[Paul Walmsley]

Hello Dirk, Luis, 

how about the patch (following in the next message) instead?  That way
we don't define OMAP2_CTRL_BASE for non-OMAP2 builds.   Build-tested
with OSK5912 default config with MMC driver enabled.

Mmh, I like to fix it in include/asm-arm/arch-omap/omap24xx.h, so I 
prefer [1].

The issue was introduced by

http://linux.omap.com/pipermail/linux-omap-open-source/2007-August/011159.html

With [1] we

- fix it where it was introduced
- have an additional #ifdef only in a header file instead of 
plat-omap/devices.c, which is IMHO better
- fix it for everybody now and in the future who directly or 
indirectly includes omap24xx.h.

Regards

Dirk

Hopefully this is just a workaround until we can get rid of these 
conditional defines for multiboot kernels.  Generally speaking, would you 
propose doing the same thing for the other conditional defines in 
include/asm-arm/arch-omap/omap24xx.h, such as OMAP2_32KSYNCT_BASE, 
OMAP2_SDRC_BASE, etc.?

Sounds like the real fix is to set these addresses in the init code
somewhere based on the omap type.

Yeah, agreed.

OMAP3430 builds now generate redefinition warnings for OMAP2_CTRL_BASE;

Until we have real fix like above: Instead of now trying to cover all 
situations where OMAP2_CTRL_BASE is undefined or redefinded (maybe 
there are some more?), I wonder why not simply make it self-dependent?

#if !defined(OMAP2_CTRL_BASE)
/* FIXME: These will go away soon */
#define OMAP2_CTRL_BASE		L4_24XX_BASE
#endif

I don't think that will work.  Consider the case of a file that 
includes both omap24xx.h and omap34xx.h during a 3430 build.  When 
omap24xx.h is processed, OMAP2_CTRL_BASE will be defined by the above 
code; then omap34xx.h will redefine it, causing the same warning.

Yup, pushed that fix.

In that time omap3 do not exist yet,
now we need to find a way, to fix this for all platforms.
I suggest to make code compilation base on define FLAGS (ifdef
ARCH_OMAP_16XX for example), and remove the lines like
 if (is_omap24xx())else i(is_omap3xxx) for example, one of the reasons is
performance, we take some machine cycle to test it (which CPU is), we will
code more (a little bit), but we can use includes based on architecture like
I suggested some time ago

#ifdedf  OMAP16xxx
#include <omap16xx.h>
else if .....

They get the idea.
So we can fix this kind of problems for each family of OMAP CPU, and we can
achieve (maybe) some performance.
my $0,02 of contribution in this discussion.
