Subject: [PATCH 01/25] ARM: OMAP2+: Move stubbed secure_sram_reserve function
to a common.c and call it __weak
omap_secure_ram_reserve_memblock is stubbed for OMAP1,2 only builds using a
ifdef check. But this results in adding CONFIG_ARCH_OMAPxx checks for
future socs that use the real function. So move this to common.c file and
call it __weak.

Subject: [PATCH 02/25] ARM: OMAP: counter-32k: Select the CR register offset
using the IP scheme
OMAP socs has a legacy and a highlander version of the
32k sync counter IP. The register offsets vary between the
highlander and the legacy scheme. So use the 'SCHEME'
bits(30-31) of the revision register to distinguish between
the two versions and choose the CR register offset accordingly.

Subject: [PATCH 04/25] ARM: OMAP5: Add minimal support for OMAP5430 SOC
OMAP5430 is Texas Instrument's SOC based on ARM Cortex-A15 SMP
architecture. It's a dual core SOC with GIC used for interrupt
handling and with an integrated L2 cache controller.
OMAP5432 is another variant of OMAP5430, with a
memory controller supporting DDR3 and SATA.
Patch includes:
- The machine specific headers and sources updates.
- Platform header updates.
- Minimum initialisation support for serial.
- IO table init

The l3 interconnect ip is same for OMAP4 and OMAP5.
So reuse the l3 error handler error code for OMAP5
as well. Also a few targets has been newly added for
OMAP5. So updating the driver for that here.

Subject: [PATCH 08/25] ARM: OMAP5: Add the WakeupGen IP updates
OMAP4 and OMAP5 share same WakeupGen IP with below few udpates on OMAP5.
- Additional 32 interrupt support is added w.r.t OMAP4 design.
- The AUX CORE boot registers are now made accessible from non-secure SW.
- SAR offset are changed and PTMSYNC* registers are removed from SAR.
Patch updates the WakeupGen code accordingly.

Subject: [PATCH 10/25] ARM: omap2+: board-generic: clean up the irq data from
board file
Move the irq_match arrays and the irq init functions of OMAP 2,3
and 4 based boards out of board-generic.c file and also rename the
irq init function to match the interrupt controller present in
the SOCs.
This is a preparatory patch to add the OMAP5 evm board's irq init
support with device tree.

Subject: [PATCH 14/25] ARM: Kconfig update to support additional GPIOs in
OMAP5
OMAP5 has 8 GPIO banks so that there are 32x8 = 256 GPIOs.
In order for the gpiolib to detect and initialize these
additional GPIOs and other TWL GPIOs, ARCH_NR_GPIO is set
to 512 instead of present 256.

Subject: [PATCH 18/25] arm: mach-mvebu: add support for Armada 370 and Armada
XP with DT
[ben.dooks@codethink.co.uk: ensure error check on of_property_read_u32]
[ben.dooks@codethink.co.uk: use mpic address instead of bus-unit's ]
[ben.dooks@codethink.co.uk: BUG_ON() if the of_iomap() fails for mpic]
[ben.dooks@codethink.co.uk: move mpic per-cpu register base ]
[ben.dooks@codethink.co.uk: number fetch should use irqd_to_hwirq()]
