The extra serial port is not available on 34xx. And the current
omap3-beagle.dts file is for omap3-beagle-xm.dts as it lists 512MB
of memory.
Please somebody submit a new omap3-beagle.dts for the original 34xx
BeagleBoard after testing it properly.

The Gumstix Overo is a computer on module using an OMAP3 processor.
This module must be plugged into an expansion board.
This patch adds a first device tree support for the Overo, using the
Tobi expansion board. The current support is able to boot and mount
the rootfs from MMC.
This patche also updates the omap3 dtb build target.
Currently working:
- mmc0 (on board microSD)
- i2c0 and i2c2 (i2c1 not used)
- led on GPIO

The device/node resources (like, IORESOURCE_MEM and IORESOURCE_IRQ)
are overwritten by hwmod resources, due to all known reasons but
that should not be the reason for not providing all the information
in the DTS blob. Ideally we should use DTS resource and use HWMOD
framework wherever required and for only specific things.
Newer platforms like, OMAP5 and AM33XX, we only support DT boot mode,
so this patch is preparation for the future where we supposed to get
rid of hwmod dependency anyway.

With the new devices (like, AM33XX and OMAP5) we now only support
DT boot mode of operation and now it is the time to start killing
slowly the dependency on hwmod, so with this patch, we are starting
with device resources.
The idea here is implemented considering to both boot modes -
- DT boot mode
OF framework will construct the resource structure (currently
does for MEM & IRQ resource) and we should respect/use these
resources, killing hwmod dependency.
If pdev->num_resources > 0, we assume that MEM & IRQ resources
have been allocated by OF layer already (through DTB).
Once DMA resource is available from OF layer, we should
kill filling any resources from hwmod.
- Non-DT boot mode
Here, pdev->num_resources = 0, and we should get all the
resources from hwmod (following existing steps)

When booted with some resource will have their name set to NULL. This can
cause later kernel crash since this is not expected by the platform code.
When we boot without DT the devices are created with platform_device_add()
which itself fixes up the missing resource names:
if (r->name == NULL)
r->name = dev_name(&pdev->dev);
The of core also fixes up the resource names when taking the information
from DT data - in __of_address_to_resource():
r->name = name ? name : dev->full_name;
When we boot OMAP with devicetree: of will create the devices based on the
DT data so the resource names are guarantied to be not NULL. Since we have
the 'ti,hwmod' tag, we remove the of created resources from the device and
re-create them based on hwmod data. If the hwmod data does not specify a
name for a resource it will be NULL.
This can cause kernel crash if the driver uses
platform_get_resource_byname() to get any resource.

Commit 5a783cbc4836 ("ARM: 7478/1: errata: extend workaround for erratum
#720789") added workarounds for erratum #720789 to the range TLB
invalidation functions with the observation that the erratum only
affects SMP platforms. However, when running an SMP_ON_UP kernel on a
uniprocessor platform we must take care to preserve the ASID as the
workaround is not required.
This patch ensures that we don't set the ASID to 0 when flushing the TLB
on such a system, preserving the original behaviour with the workaround
disabled.

Page migration encodes the pfn in the offset field of a swp_entry_t.
For LPAE, we support physical addresses of up to 36 bits (due to
sparsemem limitations with the size of page flags), requiring 24 bits
to represent a pfn. A further 3 bits are used to encode a swp_entry into
a pte, leaving 5 bits for the type field. Furthermore, the core code
defines MAX_SWAPFILES_SHIFT as 5, so the additional type bit does not
get used.
This patch reduces the width of the type field to 5 bits, allowing us
to create up to 31 swapfiles of 64GB each.

Swap entries are encoding in ptes such that !pte_present(pte) and
pte_file(pte). The remaining bits of the descriptor are used to identify
the swapfile and offset within it to the swap entry.
When writing such a pte for a user virtual address, set_pte_at
unconditionally sets the nG bit, which (in the case of LPAE) will
corrupt the swapfile offset and lead to a BUG:
[ 140.494067] swap_free: Unused swap offset entry 000763b4
[ 140.509989] BUG: Bad page map in process rs:main Q:Reg pte:0ec76800 pmd:8f92e003

Many clocks that are used to provide sched_clock will reset during
suspend. If read_sched_clock returns 0 after suspend, sched_clock will
appear to jump forward. This patch resets cd.epoch_cyc to the current
value of read_sched_clock during resume, which causes sched_clock() just
after suspend to return the same value as sched_clock() just before
suspend.
In addition, during the window where epoch_ns has been updated before
suspend, but epoch_cyc has not been updated after suspend, it is unknown
whether the clock has reset or not, and sched_clock() could return a
bogus value. Add a suspended flag, and return the pre-suspend epoch_ns
value during this period.
The new behavior is triggered by calling setup_sched_clock_needs_suspend
instead of setup_sched_clock.
