Bartlomiej Zolnierkiewicz d54322d8f6 ARM: at91: cam60: fix incorrect placement of __initdata tag
__initdata tag should be placed between the variable name and equal
sign for the variable to be placed in the intended .init.data section.

Stephen Warren 6bb27d7349 ARM: delete struct sys_timer
Now that the only field in struct sys_timer is .init, delete the struct,
and replace the machine descriptor .timer field with the initialization
function itself.

This will enable moving timer drivers into drivers/clocksource without
having to place a public prototype of each struct sys_timer object into
include/linux; the intent is to create a single of_clocksource_init()
function that determines which timer driver to initialize by scanning
the device dtree, much like the proposed irqchip_init() at:
http://www.spinics.net/lists/arm-kernel/msg203686.html

Includes mach-omap2 fixes from Igor Grinberg.

Jamie Iles 84e0cdb0a2 macb: unify at91 and avr32 platform data
Both at91 and avr32 defines its own platform data structure for
the macb driver and both share common structures though at91
includes a currently unused phy_irq_pin.  Create a common
macb_platform_data for macb that both at91 and avr32 can use.  In
future we can use this to support other architectures that use the
same IP block with the macb driver.

v2: rename eth_platform_data to macb_platform_data and allow at91_ether
to share the platform data with macb.

Dmitry Eremin-Solenikov 1754aab9bb mtd: ATMEL, AVR32: inline nand partition table access
Currently atmel_nand driver used by AT91 and AVR32 calls a special callback
which return nand partition table and number of partitions. However in all
boards this callback returns just static data. So drop this callback and
make atmel_nand use partition table provided statically via platform_data.

Hans-Christian Egtvedt: I'm fine by sending the changes for AVR32 through linux-mtd

The various declarations were removed using the following script:

  sed -i '/MACHINE_START/,/MACHINE_END/ { /\.\(phys_io\|io_pg_offst\)/d }'

From: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
To: linux-arm-kernel@lists.infradead.org
Subject: [PATCH 12/19] ARM: cam60: don't use __init for cam60_spi_{flash_platform_data,partitions}
Date: Thu,  5 Aug 2010 16:08:46 +0200
Message-Id: <1281017333-5563-12-git-send-email-u.kleine-koenig@pengutronix.de>

These two structs are referenced by cam60_spi_devices.  The latter is
copied at init time to kmalloced memory and so the copy isn't freed after
booting.  So it must not contain references to .init memory.

This isn't noticed by modpost as cam60_spi_devices is in .init.data, too.

Uwe Kleine-König 8436b41080 ARM: 6324/1: cam60: move cam60_spi_devices to .init.data
cam60_spi_devices is passed to at91_add_device_spi which calls
spi_register_board_info.  The latter makes a copy of it, so living in
.init.data is OK.

This fixes the following warning in cam60_defconfig:
	WARNING: vmlinux.o(.data+0x2a00): Section mismatch in reference from the variable cam60_spi_devices to the (unknown reference) .init.data:(unknown)
	The variable cam60_spi_devices references
	the (unknown reference) __initdata (unknown)
	If the reference is valid then annotate the
	variable with __init* or __refdata (see linux/init.h) or name the variable:
	*_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console,
