From: Alexandre Belloni <alexandre.belloni@free-electrons.com>
Setup arm_pm_idle and arm_pm_restart function pointers from
rm9200_dt_device_init() function to simplify the at91rm9200 initialization
process.
This same move is already done for the sam9s.

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.

For sama5d4, remove an indirection and the remaining need for at91_boot_soc
structure.
This will allow further cleanup.

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.

Move the ramc initialization to pm.c as it is the only user left.
This allows us to get rid of at91_dt_initialize() that was the only one called
by the init_early() function pointer of struct machine_desc.

To: linux-arm-kernel
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.
