I2c controller needs to be enabled in order to read CSPR0, CSPR1
registers function sets CGU_I2C_AUDIO_MASTER_CLOCK_ENABLE
and only clears if it wasn't previously enabled
Use divider set in register to calculate frequency rather than
hard coded divider

Last commit was just a test to see if it work this one cleans it up
a bit and should be a bit faster

Some devices(1-bit / 2-bit displays) have packed bit formats that
need to be unpacked in order to work on them at a pixel level.
This caused a few issues on 1 & 2-bit devices:
Greatly Oversized data arrays for bitmaps
Improper handling of native image data
Framebuffer data was near unusable without jumping through hoops
Conversion between native addressing and per pixel addressing
incurs extra overhead but it is much faster to do it
on the 'C' side rather than in lua.
Not to mention the advantage of a unified interface for the end programer
-------------------------------------------------------------------
Adds a sane way to access each pixel of image data
Adds:
--------------------------------------------------------------------
img:clear([color],[x1],[y1],[x2],[y2])
(set whole image or a portion to a particular value)
--------------------------------------------------------------------
img:invert([x1],[y1],[x2],[y2])
(inverts whole image or a portion)
--------------------------------------------------------------------
img:marshal([x1],[y1],[x2],[y2],[funct])
(calls funct for each point defined by rect of x1,y1 x2,y2
returns value and allows setting value of each point return
nil to terminate early)
--------------------------------------------------------------------
img:points([x1],[y1],[x2],[y2],[dx],[dy])
(returns iterator function that steps delta-x and delta-y pixels each call
returns value of pixel each call but doesn't allow setting to a new value
compare to lua pairs method)
--------------------------------------------------------------------
img:copy(src,[x1],[y1],[x2],[y2],[w],[h],[clip][operation][clr/funct])
(copies all or part of an image -- straight copy or special ops
optionally calls funct for each point defined by rect of
x1, y1, w, h and x2, y2, w, h for dest and src images
returns value of dst and src and allows setting value of
each point return nil to terminate early)
--------------------------------------------------------------------
img:line(x1, y1, x2, y2, color)
--------------------------------------------------------------------
img:ellipse(x1, y1, x2, y2, color, [fillcolor]
--------------------------------------------------------------------
Fixed handling of 2-bit vertical integrated screens
Added direct element access for saving / restoring native image etc.
Added more data to tostring() handler and a way to access individual items
Added equals method to see if two variables reference the same image address
(doesn't check if two separate images contain the same 'picture')
Optimized get and set routines
Fixed out of bound x coord access shifting to next line
Added lua include files to expose new functionality
Finished image saving routine
Static allocation of set_viewport struct faster + saves ram over dynamic
Cleaned up code
Fixed pixel get/set for 1/2 bit devices
Fixed handling for 24-bit devices (32?)
-------------------------------------------------------------------------
Example lua script to follow on forums

Also removes the sd_enable() function call. It was only used in
the debug screen on AMSv1 and not used at all on AMS v2.
For v1,obtain debug info in a struture passed to a dedicated
debug info function so that enabling and disabling the controller
isn't racy.

This brings the source to upstream commit 506b073 (though I have made some
extra commits on top of that). Notably this includes a fix for a double-free
bug that I myself introduced upstream.

AUDIOHW_SETTING() defines number of decimals and step size.
This is taken into account in sound menu but ignored in WPS.
This was not a problem so far since all drivers used 0 decimal
places and step size equal 1.

When zoomed in, the original commit made a mono bitmap (a.k.a. text) always
have the red component set to 255. This would cause drawn text to always be
red. Fixed.

Actual / of underlying linux OS should not be available to user.
I am still not sure if implementation is correct. It doesn't
perform any relative path sandboxing for example.

Original firmware update is provided as .upt file. This file
is actually ISO9660 image containing uBoot, kernel image and
UBIFS rootfs and additional control files. Installing
bootloader means patching UBIFS rootfs image.

If we use mips-rockbox-linux target resulting toolchain is
big endian. If we use mipsel-rockbox-linux build fail since
linux doesn't have separate archs for BE and LE mips. So we
tweak arch passed to linux-headers stage to fix this.

I can only assume in the course of the original conversion to fixed point
math in RbLua the fact that division by zero and NaN handling was to be
caught as a graceful exception by the floating point handler was overlooked.
As a result lua doesn't handle these exceptions and instead results in a
panic on the device.
This patch fixes this handling in the lexer for compile time Inf and Nan
results and in the luavm for runtime division by zero (Inf)
I missed the runtime exception of n%0 added checks for that as well..
