This is a little rework of the patches sent by Alexandre and some ideas coming
from Arnd.
I reworked the series so that it goes flawlessly on top of what I'd already
sent and doesn't need extra dependencies with drivers that are being cleaned-up
(at91_udc, pata_at91, etc.).
The multi-platform upcoming series from Alexandre has more dependencies. This
is why it is not stacked on top of this material. I plan to sent some kind of
preview soon so that it can be taken as a "late" pull-request if it's possible.
Thanks. Bye.

This same move is already done for the sam9s.

* [PATCH 2/7] ARM: at91: merge all SOC_AT91SAM9xxx

From: Alexandre Belloni <alexandre.belloni@free-electrons.com>
Only use SOC_AT91SAM9 for all the at91sam9 SoCs. It removes all the empty
at91sam9xxx.c SoC files. It also removes the useless at91_init_soc affectation
procedure and its "init" function pointer.
Only the SoC detection and display are kept for the at91sam9:
at91_soc_is_enabled() and at91_boot_soc.map_io() function calls are also
removed.
It enables HAVE_AT91_SMD and HAVE_AT91_UTMI for all the sam9 SoCs but this only
represents 96 bytes of uncompressed kernel code.

* [PATCH 2/7] ARM: at91: merge all SOC_AT91SAM9xxx
@ 2015-01-27 18:07 ` Nicolas Ferre
0 siblings, 0 replies; 16+ messages in thread
From: Nicolas Ferre @ 2015-01-27 18:07 UTC (permalink / raw)
To: linux-arm-kernel
From: Alexandre Belloni <alexandre.belloni@free-electrons.com>
Only use SOC_AT91SAM9 for all the at91sam9 SoCs. It removes all the empty
at91sam9xxx.c SoC files. It also removes the useless at91_init_soc affectation
procedure and its "init" function pointer.
Only the SoC detection and display are kept for the at91sam9:
at91_soc_is_enabled() and at91_boot_soc.map_io() function calls are also
removed.
It enables HAVE_AT91_SMD and HAVE_AT91_UTMI for all the sam9 SoCs but this only
represents 96 bytes of uncompressed kernel code.

* [PATCH 4/7] ARM: at91: remove at91_boot_soc
@ 2015-01-27 18:07 ` Nicolas Ferre

From: Nicolas Ferre @ 2015-01-27 18:07 UTC (permalink / raw)
To: linux-arm-kernel
From: Alexandre Belloni <alexandre.belloni@free-electrons.com>
at91_boot_soc and at91_init_soc structures are not used by any SoC, remove
their use. Also remove all the now empty SoC files.

* [PATCH 5/7] ARM: at91: change board files into SoC files

To: Alexandre Belloni, Boris BREZILLON, linux-arm-kernel, Arnd Bergmann
Cc: Jean-Christophe PLAGNIOL-VILLARD, linux-kernel, Nicolas Ferre
As board files are now DT only and can address all aspects of the SoC family,
we can rename them so that the mach-at91 directory looks cleaner.

* [PATCH 5/7] ARM: at91: change board files into SoC files
@ 2015-01-27 18:07 ` Nicolas Ferre
0 siblings, 0 replies; 16+ messages in thread
From: Nicolas Ferre @ 2015-01-27 18:07 UTC (permalink / raw)
To: linux-arm-kernel
As board files are now DT only and can address all aspects of the SoC family,
we can rename them so that the mach-at91 directory looks cleaner.

Remove the string "(Device Tree)" after the machine name because all AT91
machines use the DT nowadays.
Also change some function names to unify following the convention:
- at91sam9xxx aren't named sam9, 9xxx but with the full name
- sama5 are the ones that don't have the at91 prefix anymore.
