How many seconds are there in a year? If I tell you there are 3.155 x
10^7, you won't even try to remember it. On the other hand, who could
forget that, to within half a percent, pi seconds is  a  nanocentury.

Hi Harald,

I have applied the patch on top of u-boot-arm/master (minus slight adaptations to boards.cfg and MAINTAINERS) but the board does not seem to build properly:

uboot at lilith:~/src/u-boot-arm$ ./MAKEALL ethernut5 Configuring for ethernut5 board...
In file included from /home/uboot/src/u-boot-arm/include/asm/arch/gpio.h:18,

                  from at91sam9260_devices.c:29:

/home/uboot/src/u-boot-arm/include/asm/arch/at91_pio.h:91: error:

Hi Albert,

Thanks for taking the time to look into this. It built properly at the time it had been published, but fails with the current u-boot-arm/master.

We will look into this and provide an update within the next few days.

Regards,

Harald

Dear Albert,

I'll take it -- just hadn't had enough time to get to applying it so far.

Amicalement,
