[U-Boot] [PATCH] at91: Support for the at91sam9g20 : Atmel 400Mhz ARM 926ej-s SOC.

[U-Boot] [PATCH] at91: Support for the at91sam9g20 : Atmel 400Mhz ARM 926ej-s SOC.

[Nicolas Ferre]

AT91sam9g20 is an evolution of the at91sam9260 
with a faster clock speed.

Here is the chip page on Atmel website:

Hm.... to me it  seems  that  the  new  files  added  are,  with  the
exception  of  "at91sam9260ek"  into "at91sam9260ek" renames, more or
less identical copies of the board/atmel/at91sam9260ek code ?


Please use common code and avoid such code duplication.

NAK.

Please find a more generic way of doing this.  There should be no 
board/cpu specific #ifdefs in common drivers.  While you're at it, fix 
up the existing ones.

Wolfgang,

Ok, so a new patch follows with much clever adding of at91sam9g20 (Comes 
from Justin Waters).

Thanks for your comments, regards,

[U-Boot] [PATCH] at91: Support for the at91sam9g20 : Atmel 400Mhz ARM 926ej-s SOC.

[Nicolas Ferre]

AT91sam9g20 is an evolution of the at91sam9260 with a faster clock speed.

The AT91SAM9G20-EK board is an updated revision of the AT91SAM9260-EK board.
It is essentially the same, with a few minor differences.

Here is the chip page on Atmel website:

Ben,

Maybe we can separate the two topics in two separate actions.
I propose that we go on with this patch for at91sam9g20 adding and, 
after this, we can concentrate on chasing #ifdefs in drivers.

Best regards,

Tell me if a configuration variable that I setup in the macb.h file 
depending on CPU is acceptable ?
Here is the snippet :
in drivers/net/macb.h

+/* MACB IP used by AVR32 & AT91 have two
+ * different layout for USRIO register. */
+#if !defined(CONFIG_AVR32)
+/* Use AT91 USRIO layout */
+#define CONFIG_MACB_USRIO_CFG1 1
+#endif

And then I use CONFIG_MACB_USRIO_CFG1 in macb.c

This will prevent me from setting this variable in every CPU config file...

Bye,
