The freescale arm i.MX series platform can support this driver, and
usually the arm cpu works in the little endian mode by default, while
device tree entry value is stored in big endian format, we should use
be32_to_cpup() to handle them, after modification, it can work well
both on the le cpu and be cpu.

m68k's asm/shm.h header has been part of the tree ever since m68k
support got added in v1.3.94. (It started as /include/asm-m68k/shm.h and
moved to its current location a few years ago.) It seems it was never
used: no file ever included it and nothing used the macros it defines.
(Actually, from v2.5.46 until v2.6.29-rc3 it was included by m68knommu's
asm/shm.h. But that header was just a very thin wrapper for this header
and was itself unused too.)
This header can safely be removed.

There are five entirely unused headers in arch/m68k/include/asm. Nothing
includes these headers. And a few tests found no hits for the things
they provide (which makes sense).
MC68332.h, mac_mouse.h, and mcfmbus.h are all unused since at least
v2.6.12-rc2 (I didn't bother looking further back than that).
apollodma.h is unused since v2.6.19: commit
2ed0ce5b57 ("m68k/Apollo: Remove obsolete
arch/m68k/apollo/dma.c") removed the last file interested in that
header.
And everything interested in <asm/sbus.h> was removed in the v2.6.28
release cycle. The last occurrence of "sbus.h" was deleted with commit
0c0db98b50 ("sparc: Remove
Documentation/sparc/sbus_drivers.txt"). I'm not sure whether anything
relevant for m68k was included in v2.6.27, but it doesn't really matter.

In the real time use-case when SGX is used for rendering to FB buffers it has been
observed that, the available memory from framebuffer driver is not sufficient for
SGX under certain cases (like 16-bit WVGA resolution). SGX requires 2 swap buffers
with each of the buffers aligned to lcm(line_length, PAGE_SIZE).
Inorder to satisfy this requirement, we have two options,
- Increase number of FB buffers (LCD_NUM_BUFFERS) to 3. This is not
recommended as we end up wasting huge memory in most of the cases.
- Align FB buffers to lcm(line_length, PAGE_SIZE).This ensures framebuffer
size is increased to satisfy SGX requirements keeping alignment intact.
This patch makes sure that FB allocates buffers aligned to above formula.

Users may call FBIOPUT_VSCREENINFO ioctrl to do pan display.
This ioctrl relies on fb_set_var() to do the job. fb_set_var()
calls custom fb_set_par() method and then calls custom
fb_pan_display() method. The current implementation of mx3fb
reinitializes IPU display controller every time the custom
fb_set_par() method is called, which makes the screen flash
if fb_set_var() is called to do panning frequently. This patch
compares the new var info with the cached old one to decide
whether we really need to reinitialize IPU display controller.
We ignore xoffset and yoffset update because it doesn't require
to reinitialize the controller. Users may specify activate field
of var info with FB_ACTIVATE_NOW and FB_ACTIVATE_FORCE to
reinialize the controller by force.

Users may call FBIOPUT_VSCREENINFO ioctrl to do pan display.
This ioctrl relies on fb_set_var() to do the job. fb_set_var()
calls the custom fb_set_par() method and then calls the custom
fb_pan_display() method. Before calling the custom fb_pan_display()
method, info->var is already updated from the new *var in fb_set_var().
And, the custom fb_pan_display() method checks if xoffset and yoffset
in info->var and the new *var are different before doing actual panning,
which prevents the panning from happening within fb_set_var() context.
This patch caches the current var info locally in mx3fb driver so that
pan display with fb_set_var is supported.

there is no noticeable benefit for multiple cores to process one
job ring's output ring: in fact, we can benefit from cache effects
of having the back-half stay on the core that receives a particular
ring's interrupts, and further relax general contention and the
locking involved with reading outring_used, since tasklets run
atomically.

It has been observed that in zero-loss benchmarks, when a
slow traffic rate is being tested, the IRQ timer coalescing
parameter was set too high, and the ethernet controller
would start dropping packets because the job ring back half
wouldn't be executed in time before the ethernet controller
would fill its buffers, thereby significantly reducing the
zero-loss performance figures.
Empirical testing has shown that the best zero-loss performance
is achieved when IRQ coalescing is set to minimum values and/or
turned off, since apparently the job ring driver already implements
an adequately-performing general-purpose IRQ mitigation strategy
in software.
Whilst we could go with minimal count (2-8) and timing settings
(192-256), we prefer just turning h/w coalescing altogether off
to minimize setkey latency (due to split key generation), and
for consistent cross-SoC performance (the SEC vs. core clock
ratio changes).
