This patch adds support for the Broadcom GISB arbiter bus timeout/error
handler. GISB is a proprietary bus used by Broadcom Set Top Box
System-on-a-chip devices (BCM7xxx) which allows multiple masters and
clients to be interfaced with each other.

The bus arbiter offers support for generating two interrupts towards the
host CPU, thus allowing us to "catch" clock gated masters, or masters
being volontarily blocked for powersaving purposes, or do general system
troubleshooting.

We also register a hook with the ARM fault exception handling to allow
printing a more informative message than "imprecise external abort at
0x00000000" for instance.

Add AM4372 information to handle L3 error.

AM4372 has two clk domains 100f and 200s. Provide flagmux and data
associated with it.

NOTE: Timeout doesn't have STDERRLOG_MAIN register. And per hardware
team, L3 timeout error cannot be cleared the normal way (by setting
bit 31 in STDERRLOG_MAIN), instead it may be required to do system
reset. L3 error handler can't help in such scenarios.

Hence indicate timeout target offset as L3_TARGET_NOT_SUPPORTED as
done for undocumented bits.

DRA7 is distinctly different from OMAP4 in terms of masters and clock
domain organization. There two main clock domains which is divided as
follows:
     <0x44000000 0x1000000> is clk1 and clk2 is the sub clock domain
     <0x45000000 0x1000> is clk3

Add all the data needed to handle L3 error handling on DRA7 devices
and mark clk2 as subdomain and provide a compatible flag for
functionality. Other than the data difference the hardware blocks
involved are essentially the same.

While OMAP4 and OMAP5 had 3 separate clock domains, DRA7 has only 2
and the first one then is internally divided into 2 sub clock domains.

To better represent this in the driver, we use the concept of submodule.

The address defintions in the devicetree is as per the high level
clock domain(module) base, the sub clockdomain/subdomain which shares
the same register space of a clockdomain is marked in the SoC data as
L3_BASE_IS_SUBMODULE.

L3_BASE_IS_SUBMODULE is used as an indication that it's base address is
the same as the parent module and offsets are considered from the same
base address as they are usually intermingled.

Other than the base address, the submodule is same as a module as it is
functionally so.

L3 error may be triggered using Debug interface (example JTAG) or
due to other errors, for example an opcode fetch (due to function
pointer or stack corruption) or a data access (due to some other
failure). NOC registers contain additional information to help aid
debug information.

With this, we can enhance the error information to more detailed form:

Today we get error such as
L3 Custom Error: MASTER MPU TARGET L4PER2

But since the actual instruction triggerring the error Vs the point
at which we report error may not be aligned, it makes sense to try
and provide additional information - example the type of operation
that was attempted to being performed can help narrow the debug down
further.

This helps provide log such as:

Errors that cannot be cleared (determined by reading REGERR register)
are currently handled by masking it. Documentation states that REGERR
"Checks which application/debug error sources are active" - it does not
indicate that this is "interrupt status" - masked out status represented
eventually in the irq line to MPU.
For example:

Lets say module 0 bit 8(0x100) was unclearable, we do the mask it from
generating further errors. However in the following cases:
a) bit 9 of Module 0
OR
b) any bit of Module 1+
occur, the interrupt handler wrongly assumes that the raw interrupt
status of module 0 bit 8 is the root cause of the interrupt, and
returns. This causes unhandled interrupt and resultant infinite
interrupts.

Fix this scenario by storing the events we masked out and masking raw
status with masked ones before identifying and handling the error.

Current interrupt handler does the first level parse to identify the
slave and then handles the slave even identification, reporting and
clearing of event as well. It is hence logical to split the handler
into two where the primary handler just parses the flagmux till it
identifies a slave and the slave handling, reporting and clearing is
done in a helper function.

While at it update the documentation in kerneldoc style.

As per Documentation (OMAP4+), then masterid is infact encoded as
follows:
"L3_TARG_STDERRLOG_MSTADDR[7:0] STDERRLOG_MSTADDR stores the NTTP
master address. The master address is the concatenation of Prefix &
Initiator ConnID. It is defined on 8 bits. The 6 MSBs are used to
distinguish the different initiators."

So, when we matchup currently with the master ID list, we never get a
proper match other than when MPU is the master (thanks to 0).

Now, on other platforms such as AM437x, this tends to be bits[5:0].

Fix this by using the relevant 6MSBits to identify the master ID for
standard and custom errors.

This allows us to encompass target information and flag mux offset that
points to the target information into a singular structure. This saves
us the need to look up two different arrays indexed by module ID for
information.

This allows us to reduce the static target information allocation to
just the ones that are documented.

DRA7xx SoC has the same l3-noc interconnect ip (as OMAP4 and OMAP5), but
AM437x SoC has just 2 modules instead of 3 which other SoCs have.

So, stop using direct access of array indices and use of->match data and
simplify implementation to benefit future usage.

While at it, rename a few very generic variables to make them omap
specific. This helps us differentiate from DRA7 and AM43xx data in the
future.

NOTE: None of the platforms that use omap_l3_noc are non-device tree
anymore. So, it is safe to assume OF match here.

On DRA7, unlike on OMAP4 and OMAP5, the flag mux input numbers used
to indicate the source of errors are not continous. Have a way in the
driver to catch these and WARN the user of the flag mux input thats
either undocumented or wrong.

In the similar vein, Timeout errors in AM43x can't be cleared per h/w
team, neither does it have a STDERRLOG_MAIN to clear the error.

Further, the mux bit offset might not even be indexed into our array
of known mux input description, in which case we'd have a abort.

So, define a static range check for bit description and any definition
which has target_name set to NULL (the ones that are not populated or
ones that are specifically marked in the case of discontinous input
numbers), can handle the same gracefully. Upon occurance of error from
such sources, mask it. Otherwise, we'd have an infinite interrupt
source without any means to clear it.

NOTE: follow on patch ensures that these masked bits are ignored.

Currently the target instance information is organized indexed by bit
field offset into multiple arrays.

1. We currently have offsets specific to each target associated with each
clock domains are in seperate arrays:

l3_targ_inst_clk1
l3_targ_inst_clk2
l3_targ_inst_clk3

2. Then they are organized per master index in l3_targ.

3. We have names in l3_targ_inst_name as an array to array of strings
corresponding to the above with offsets.

Simplify the same by defining a structure for information containing
both target offset and name. this is then stored in arrays per domain
and organized into an array indexed off domain.

The array is still indexed based on bit field offset.
