ata-creativezen looks like a legit memory-trashing bug, the rtc fixes
are bitwise inversion of a bool, and the remaining are just unused
static variables.

Cortex-M processors don't have an MMU, but can still have caches
that need software management, so on those platforms we don't want
to include the MMU related functions.
While here, remove an outdated section of a comment referring to
deprecated cache maintenance functions which no longer exist.

It's usually only called from init() in main.c, so this is safe.
There is one more call in system-dm320.c from system_init(), but
that's also "safe". I don't know if it's okay to call i2c_init()
twice, but presumably it works...

Instead of putting "#ifdef LCD_STRIDEFORMAT" at every usage of the
macro it's simpler to have config.h define LCD_STRIDEFORMAT to the
default of horizontal stride when the target leaves it unspecified.

IMHO the current name is somewhat misleading:
- usb_drv_send() is blocking and we have usb_drv_send_nonblocking()
for the non-blocking case. This inconsistent naming can only
promote confusion. (And what would we call a blocking receive?)
- Other hardware abstraction APIs in Rockbox are usually blocking:
storage, LCD, backlight, audio... in other words, blocking is the
default expected behavior, with non-blocking calls being a rarity.

Do not introduce any change for M:Robe 500 as it uses the two LCD frames

AVR interrupt signal can remain active if the state has changed during
state read. In such case, there won't be intterupt and the interface
would appear unresponsive until AVR thread received event (e.g. USB
connection/disconnect). Solve the issue by not waiting for event if AVR
interrupt signal is active prior to event wait.

Make it possible for target to provide voltage, percentage and time to
empty values. The voltage measurement is nice to have in debug menu even
if the actions are taken only based on percentage. Perform battery level
estimation based on voltage only if percentage is not available.
Use time to empty based on actual power consumption. This makes the
estimated runtime displayed in Rockbox Info to react to backlight
setting. The bq27000 updates time to empty estimate every 5.12 seconds
so it is possible to see the estimate with backlight off on the screen
if user enters Rockbox Info, activates hold switch, waits 11 seconds and
releases the hold switch.

If the commands repeatedly fail it is likely that the AVR is not
programmed. In such case simply continue normal operation. This is
especially important in bootloader as it makes it possible to load new
rockbox build using bootloader USB mode. Otherwise, the only recovery
option would be to use I2C serial.

Disabling double buffering results in expected CPPI TX behaviour. With
the double buffering enabled, sending single ZLP resulted in two ZLPs
being available. The two ZLPs is problematic because this causes Windows
to reset USB device after failed SCSI command.
The problematic sequence on Windows 10 was as follows:
* Host sends SCSI Mode Sense(6) Informational Exceptions Control(0x1C)
* Device sends ZLP
* Device sends command failed response
With endpoint double buffering enabled the ZLP was read twice by host.
As host was expecting command response on the second read (and got ZLP
instead), host attempts recovery by resetting USB device and retrying.

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
