This change adds functionality to operate on reserved SRAM partitions
described in device tree file. Two partition properties are added,
"pool" and "export", the first one allows to share a specific partition
for usage by a kernel consumer in the same manner as it is done for
the whole SRAM device, and "export" property provides access to some
SRAM area from userspace over sysfs interface. Practically it is
possible to specify both properties for an SRAM partition, however
simultaneous access from a kernel consumer and from userspace is not
serialized, but still the combination may be useful for debugging
purpose.
The change opens the following scenarios of SRAM usage:
* updates in a particular SRAM area specified by offset and size are
done by bootloader, then this information is utilized by the kernel,
* a particular SRAM area is rw accessed from userspace, the stored
data is persistent on soft reboots,
* a device driver secures SRAM area for its purposes,
* etc.
Note, strictly speaking the added optional properties describe policy
of SRAM usage, rather than hardware, but here the policy mostly
resembles flash partitions in devicetree, which is undoubtedly
a very popular option but it does not describe hardware.

Align compatible strings for several IP blocks present on Tegra chips
with the latest doctrine from the DT maintainers:
http://marc.info/?l=devicetree&m=142255654213019&w=2
The primary objective here is to avoid checkpatch warnings, per:
http://marc.info/?l=linux-tegra&m=142201349727836&w=2
DT binding text files have been updated for the following IP blocks:
- PCIe
- SOR
- SoC timers
- AHB "gizmo"
- APB_MISC
- pinmux control
- UART
- PWM
- I2C
- SPI
- RTC
- PMC
- eFuse
- AHCI
- HDA
- XUSB_PADCTRL
- SDHCI
- SOC_THERM
- AHUB
- I2S
- EHCI
- USB PHY
N.B. The nvidia,tegra20-timer compatible string is removed from the
nvidia,tegra30-timer.txt documentation file because it's already
mentioned in the nvidia,tegra20-timer.txt documentation file.
This second version takes into account the following requests from
Rob Herring <[email protected]>:
- Per-IP block patches have been combined into a single patch
- Explicit documentation about which compatible strings are actually
matched by the driver has been removed. In its place is implicit
documentation that loosely follows Rob's prescribed format:
"Must contain '"nvidia,<chip>-pcie", "nvidia,tegra20-pcie"' where
<chip> is tegra30, tegra132, ..." [...] "You should attempt to
document known values of <chip> if you use it"

Some SoCs need parts of their sram for special purposes. So while being part
of the peripheral, it should not be part of the genpool controlling the sram.
Therefore add the option to define reserved regions as subnodes of the
sram-node similar to defining reserved global memory regions.

Allwinner has electric fuses (efuse) on their line of chips. This driver
reads those fuses, seeds the kernel entropy and exports them as a sysfs
node.
These fuses are most likely to be programmed at the factory, encoding
things like Chip ID, some sort of serial number, etc. and appear to be
reasonably unique.
While in theory, these should be writeable by the user, it will probably
be inconvenient to do so. Allwinner recommends that a certain input pin,
labeled 'efuse_vddq', be connected to GND. To write these fuses however,
a 2.5 V programming voltage needs to be applied to this pin.
Even so, they can still be used to generate a board-unique mac from,
board unique RSA key and seed the kernel RNG.
On sun7i additional storage is available, this is initially used for an
UEFI BOOT key, Secure JTAG key, HDMI-HDCP key and vendor specific keys.
Currently supported are the following known chips:
Allwinner sun4i (A10)
Allwinner sun5i (A10s, A13)
Allwinner sun7i (A20)

This driver requests and remaps a memory region as configured in the
device tree. It serves memory from this region via the genalloc API. It
optionally enables the SRAM clock.
Other drivers can retrieve the genalloc pool from a phandle pointing to
this drivers' device node in the device tree.
The allocation granularity is hard-coded to 32 bytes for now, to make the
SRAM driver useful for the 6502 remoteproc driver. There is overhead for
bigger SRAMs, where only a much coarser allocation granularity is needed:
At 32 bytes minimum allocation size, a 256 KiB SRAM needs a 1 KiB bitmap
to track allocations.

alternative. These new bindings also happen to be deployed in the
field and were previously submitted for consideration here:
https://lists.ozlabs.org/pipermail/devicetree-discuss/2012-May/015556.html
The advantages of the new bindings are that they are similar to the
I2C EEPROMs and they don't conflate read-only and the address width
modes in a binary encoded blob.
