PATCH v2 1/1 at91: Add support for taskit AT91SAM9G20 boards

This adds support for the AT91SAM9G20 boards by taskit GmbH. Both boards, Stamp9G20 and PortuxG20, are integrated in one file. PortuxG20 is basically a SBC built around Stamp9G20.

Are more taskit based boards expected?
If not taskit/stamp9G20 could be reduced to just taskit

Yes, there are more taskit boards expected.

Change immediates to logical #defines

Sorry, I don't get that clearly. In the moment I would take that to mean that I should do something like
#define CONFIG_BOOT_PARAMS CONFIG_SYS_SDRAM_BASE + 0x100
in the appropriate place
and use here:
gd->bd->bi_boot_params = CONFIG_BOOT_PARAMS
or am I wrong?

PATCH v2 1/1 at91: Add support for taskit AT91SAM9G20 boards

Quoted 23 lines · Achim Ehrlich

Quoted 21 lines · Achim Ehrlich

This adds support for the AT91SAM9G20 boards by taskit GmbH. Both boards, Stamp9G20 and PortuxG20, are integrated in one file. PortuxG20 is basically a SBC built around Stamp9G20.

Sorry, I don't get that clearly. In the moment I would take that to mean that I should do something like
#define CONFIG_BOOT_PARAMS CONFIG_SYS_SDRAM_BASE + 0x100
in the appropriate place
and use here:
gd->bd->bi_boot_params = CONFIG_BOOT_PARAMS
or am I wrong?

I was referring to 9 and 5 arguments to at91_set_pio_output You could also change the bi_boot_params but that isn't as important.

PATCH v3 1/1 at91: Add support for taskit AT91SAM9G20 boards

Dear Achim Ehrlich,

Quoted 1 line

are there still objections to our patch or has it just got forgotten?

Just not dealt with (#error: no custodian) :)

Can you please rebase,
and use boards.cfg instead of global Makefile?

Best Regards,
Reinhard
