it is provided as 2 inline functions in a header called checksum.h.

This makes it so the thread cached variable is only read if building

This fixes the functions for bootloaders so they do not have to import

This was introduced in e13c600133 back
when the author was trying to optimize the LCD code with DMA. For
whatever reason this broke the bootloader for the last 10 years or so
and no one could figure out why. This is now fixed.
However the bootloader is still currently broken in HEAD due to recent
changes to the LCD code. A fix for that is not yet known.

This overhauls most of the code to be easier to understand in terms
of the interactions with the flash. I found the original to be rather
confusing with how it kept switching between byte and word offsets.
My solution was to make all external access to the flash in terms of
sectors and bytes. Whatever the flash uses internally is now handled
by the subroutines for performing the erase, program, and verify
operations.
This helps make it far more consistent for the code that actually uses
these operations as they do not need to concern themselves with word
sizes and offsets anymore.
As a side effect of this change the flash operations are now done
entirely by subroutines; even the batch operations that used to use
custom loops.
Additionally some functions were merged with other functions in order
to reduce the amount of functions as well as consolidating common
code fragments.

Some mSATA adapters seem to have trouble working with Rockbox using our
normal PIO timings; the timing value we use is probably out of spec and
is different to the OF. Switch to using the OF's timings according to
which PIO mode we select. This may not completely resolve problems with
these adapters but allows Rockbox to boot and play audio.

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] 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_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)

In short, the display fading back in after a pause resuming interferes
with the audio codec, causing BadThings(tm) that cannot be recovered from
This really is just avoiding a known trigger; there's no guarantee this
condition won't occur under random circumstances during normal use,
and there's no good way to work around this from within rockbox.
I suspect the underlying problem is that both the display control and
codec control share an i2c bus, but the kernel drivers implementing them
isn't using proper linux bus access/locking.

Basically, existing sizes apply for <= 48KHz audio. Up to 96K,
we double the mix buffer. up to 192K, we double it again.
Will help reduce the interrupt load and overall latency, keeping it
roughtly constant as a function of time, regardless of bitrate.
(It is acutally a fixed-size buffer, statically-allocated to handle the
worst-case bitrate the player supports. However, at runtime if we are
using a lower bitrate we will only use a portion of it in order to keep
latancies down)

Fixes deficiencies with the button system on the X3
The x3 has an interesting button layout.
Multiple key presses are NOT supported unless
[BUTTON_POWER] is one of the combined keys
As you can imagine this causes problems as the power button takes
precedence in the button system and initiates a shutdown if the
key is held too long
instead of BUTTON_POWER use BUTTON_PWRALT in combination with other keys
IF using as a prerequsite button then BUTTON_POWER should be used
Multiple buttons are emulated by button_read_device but there are a few
caveats to be aware of:
Button Order Matters!
different keys have different priorities, higher priority keys 'overide'
the lower priority keys
VOLUP[7] VOLDN[6] PREV[5] NEXT[4] PLAY[3] OPTION[2] HOME[1]

Later when the alloc fails buflib will keep try to free items
in order to satisify the request this crashes in the sim
I suspect this behavior holds true on device as well
but I havent verified this as of yet.
patch adds minimal overhead to the buflib and panics when the size is too small

The FC-1307 CF->SD converter that is the basis of a lot of ATA->CF
devices (including several iflash iFlash models) claims to not support
ATA power management commands.
Rockbox unconditionally issues those commands as support is mandated by
the ATA spec. This patch checks the capability bit, and if it's not
supported, does not attempt to put the ATA subsystem to sleep.
It is not clear if the problems lie with the SLEEP commands or the wakeup
process, but who knows where else the FC1307 violates the ATA specs, and
reliability is much more important than power savings.

The "try to mount as superfloppy" fails with some partitioning layouts
because sector 0 can have a mostly-valid FAT32 signature. However, in
all dumps I've looked at, sector 0's fsinfo offset value points at a place
which lacks the fsinfo signature.
Resolves FS#13213, no known regressions.

This was broken when the major update to iap was comitted.
ia-lingo7.c created and various iap related files modified.
On 4G, 6G and Nano 1/2Gen iPods the remote will function
even though the radio won't.
Tested on 4G Greyscale, 4G Color, 4G Photo, 4G Mini 1st Gen,
4G Mini 2Gen, Nano 1G, Nano 2G, Video 5G, Video 5.5G

Linux offers the high-level i2c-dev driver to directly access the
i2c bus(ses) on the system. This system device is used to get rid
of the (rather silly) radio chip kernel module for ypr0 target and
correctly enables radio access also for the ypr1 target.
fm-radio chip is located on i2c-0 bus on the ypr0 target while it
is located on i2c-1 bus on the ypr1 target.
Power-up (RST) pin is also handled for both targets, which is wired
to another GPIO of the i.MX 37 platform.
Additionally, this patch simplifies the RDS low-level handling by
exploiting the Si4709 debug interface which comes with a mutex
protection as free bonus.

For reasons that are still unclear, the 'ncbss' region was overlapping
the "audiobuffer" when linked with 2.21, but okay with 2.20.
Fixed it by making the audiobuffer explcitly use the current position
instead of relying on it being implicit.
With this change, portalplayer-based targets generate working binaries
when built with binutils 2.21 or newer.
This bug also theoretically affects imx233/imx31 targets as they
also have NOCACHE_BASE games in their linker scripts, but I lack
access to one to test with.

This appears to solve _some_ of the crashes experienced when using
gcc494 on the multicore PP targets (eg most older ipods).
(With this change, the asm vs plain-C versions behave identically)
corelock_lock(), corelock_unlock(), and corelock_trylock() were declared
with the 'naked' attribute. However, naked functions are only allowed
to have 'Basic Asm' components, and we used some extended asm, but
without declaring clobbered registers, making assumptions about register
arguments, and also directly returned to the caller via asm code.
This is what the GCC docs have to say about this stuff:
"While using extended asm or a mixture of basic asm and C code may
appear to work, they cannot be depended upon to work reliably and are
not supported."

This allows for a superfloppy that has MBR-like data in the BPB.
this solves FS#12294 while allowing arbitrary partition types.

If we aren't going to check for the partition type, we don't need the array of
known FAT partition types.

Instead of only mounting partitions with a FAT partition type, try any
partition that isn't type 0 (unallocated) or 5 (extended). This makes it easier
to reformat SDXC cards which have the exFAT partition type, and also brings us
in line with pretty much every other OS at this point. Anything with a
valid-looking FAT superblock will get mounted.

On some devices, the button driver allows a "software poweroff" by long-
pressing a certain key. This behavior is inconvnient when that button needs
to be held down for other purposes, such as moving the cursor in rockpaint
or sgt-untangle.
This patch allows selectively disabling the software poweroff (enabled by
default) from both core and plugin code.
