cfeeb7889d Lcd save function pointer to frame buffer get_address_fn before loops
Calling multiple levels of indirection in a loop slows things down

Really these need to be rewritten to take a start and end address
like most of the rest of the codebase

But this is safer without having test hardware in hand

ffee661ab7 lcd framebuffer - Bugfix ensure proper alignment
-- apparenty 0x4 aligned doesn't work properly

requires 0x8 alignment at least for the h10 20gb
but enabled for all arm processors

assign the default framebuffer to the default_vp as well

792f05f82a lcd: Wrap anonymous union initializer in braces
GCC 4.9.4 is apparently smart enough to compile this, but 4.4.4 is not.

3237ae4a4f LCD core move buf ptr and address look up function viewport struct
I'm currently running up against the limitations of the lcd_draw functions
I want these functions to be able to be used on any size buffer not
just buffers with a stride matching the underlying device

[DONE] allow the framebuffer to be decoupled from the device framebuffer
[DONE need examples] allow for some simple blit like transformations
[DONE] remove the device framebuffer from the plugin api
[DONE}ditto remote framebuffer
[DONE] remove _viewport_get_framebuffer you can call struct *vp = lcd_set_viewport(NULL) and vp->buffer->fb_ptr

while remote lcds may compile (and work in the sim) its not been tested on targets

[FIXED] backdrops need work to be screen agnostic

[FIXED] screen statusbar is not being combined into the main viewport correctly yet

[FIXED] screen elements are displayed incorrectly  after switch to void*

[FIXED] core didn't restore proper viewport on splash etc.

[NEEDS TESTING] remote lcd garbled data

[FIXED] osd lib garbled screen on bmp_part

[FIXED] grey_set_vp needs to return old viewport like lcd_set_viewport

[FIXED] Viewport update now handles viewports with differing buffers/strides by copying to the main buffer

[FIXED] splash on top of WPS leaves old framebuffer data (doesn't redraw)
[UPDATE] refined this a bit more to have clear_viewport set the clean bit and have skin_render do its own screen clear
scrolling viewports no longer trigger wps refresh
also fixed a bug where guisyncyesno was displaying and then disappearing

[ADDED!] New LCD macros that allow you to create properly size frame buffers in you desired size without wasting bytes
(LCD_ and LCD_REMOTE_)
LCD_STRIDE(w, h) same as STRIDE_MAIN
LCD_FBSTRIDE(w, h) returns target specific stride for a buffer W x H
LCD_NBELEMS(w, h) returns the number of fb_data sized elemenst needed for a buffer W x H
LCD_NATIVE_STRIDE(s) conversion between rockbox native vertical and lcd native stride (2bitH)
test_viewports.c has an example of usage

[FIXED!!] 2bit targets don't respect non-native strides
[FIXED] Few define snags

d7871914ac Fix dangerous casts
On Windows 64-bit, the size of long is 32-bit, thus any pointer to long cast is
not valid. In any case, one should use intptr_t and ptrdiff_t when casting
to integers. This commit attempts to fix all instances reported by GCC.
When relevant, I replaced code by the macros PTR_ADD, ALIGN_UP from system.h

a1842c04f9 lcd-24bit: Introduce a 24-bit mid-level LCD driver
With LCD driver all calculation will be performed on RGB888 and the hardware/OS
can display from our 24bit framebuffer.

It is not yet as performance optimized as the existing drivers but should be
good enough.The vast number of small changes is due to the fact that
fb_data can be a struct type now, while most of the code expected a scalar type.

lcd-as-memframe ASM code does not work with 24bit currently so the with 24bit
it enforces the generic C code.

All plugins are ported over. Except for rockpaint. It uses so much memory that
it wouldnt fit into the 512k plugin buffer anymore (patches welcome).

0250be1d67 lcd-16bit: Split out some functions to lcd-color-common.c
An upcoming lcd-24bit.c driver will re-use a lot of code from the 16bit
drivers, so prepare for that.
