Subject: [PATCH 01/14] 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 02/14] 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 04/14] 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

Subject: [PATCH 07/14] ARM: OMAP5: l3: Add l3 error handler support for omap5

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 08/14] 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 10/14] 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 14/14] 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.
