556954141e AVR: Add support for AVR chips with 24-bit Program Counter register 
The main challenge is to change the context switch code to be aware of the
extra byte that is saved on stack during call and intterupt. This relates also
to the task startup and signal handling.

99aab135b2 AVR: Make setting of XDIV optional for platforms that support it 
Put setting of XDIV into ifdef since not AVR platforms support it.

462307f4b7 AVR: Clear EIND on system start-up 
For AVR chips (Atmega2560) Program Counter register larger than 16 bits
EIND represents the most significant byte that is used for EICALL and EIJMP
instructions.

Setting of EIND is normally managed by compiler, but I have seen a situation
when for first 64K flash segment compiler didn't set EINT explicitly. Thus
setting EIND at system startup makes sure we are safe.

9a4a06bf47 AVR: Explicitly disable interrupts as the first step of system init 
Disabling interrupts at the very beginning of system init does not
make sense after reset since interrupts are disabled anyway. But
it is very convenient for debugging purposes, in situations when the
system misbehaves and ocassionally jumps to zero.

ff5e589f76 AVR: add support for TCGETS and TCSETS terminal controls 
Sometimes I need UART to support binary data transfer, TCSETS/TCGETS allow
stwitching into binary mode.

d6f6e41a36 AVR: Fix linking error for AVR platforms that have no ARCH_HAVE_LEDS defined 
Minor bug while working on Arduino Mega support. I didn't add support
for ARCH_HAVE_LEDS and have it undefined in .config. To my surprise compilation
failed since AVR code had a related function compiled in.

8f8b88f532 AVR: Fix resulting nuttx file name when EXEEXT is not empty 
arch/avr/Makefile is adding extra EXEEXT to the
nuttix image file. This was not discovered since in most configurations
EXEEXT is empty string.

41bdcd16b8 Change notation of PCH and PCL registers into PC0 and PC1 
This is for forthcoming Atmega2560 support. The Atmega2560 has 24-bit PC
thus, PCH and PCL would become PCH, PCM and PCL (M for Middle). The problem
that in this notation PCM is equivalent to former PCH. This makes compatable
porting kind of difficult, at least for my taste.

Instead PCH becomes PC0 and PCL becomes PC1 (think of the index as order of
bytes pushed to stack when call is performed, PC0 as MSB goes first, PC1
goes to stack second, and for 24-bit PC, PC2 as LDB goes last).

0998876ef6 AVR: Fix interrupt bombing during a context switch 
TCB_RESTORE macro has a problem when restoring Status Register
and returning from the function (in up_fullcontextrestore()) as non-atomic action.

If there is some frequently occurring interrupt, chances are that we will
enter the interrupt handler just before ret is called.
The handler may cause a context switch which, when unrolled, will
execute up_fullcontextrestore() function that employs TCB_RESTORE.
It will be interrupted again just before return, leaving part of context
switch content un-popped again, etc... Thus, chances are that the stack will
eventually blow.

Note that this is not some edge condition fix. This bug was discovered when
testing AVR with UART configured to work on 115200 baud rate.

31b8137956 There used to be two ways to pass parameters to new tasks, depending upon the configuration: Either (1) argv[] as created as an array with each string strdup'ed. Or (1) argv[] array and strings were created on the stack before the new task was started. Now, there is only one way, way (1). Way (2) might be slightly more compact, but this is not worth carry the complexity of two different ways of doing the same thing. 2014-09-01 15:39:34 -06:00
