arpadbuermen 4045406ed8 Added support for fine-grained bootloader and flash locking in samd.c 
lock_flash and lock_bootprot currently support only locking the whole flash and locking the maximal leading flash chunk (32k). 
An optional numerical parameter is added. It can be specified in decimal or 0x prefixed hexadecimal. 
For samd21 'lock_bootprot 0' locks the first 32k of flash while 'lock_bootprot 6' locks the first 512 bytes. 'lock_bootprot 0' is equivalent to 'unlock_bootprot'.  
Similarly, 'lock_flash <number>' locks the flash segments corresponding to zeros in the binary representation of the given number. 
'lock_flash 0xffff' is equivalent to 'unlock_flash'. 
If the optional parameter is not given both commands work as previously.

Sean Cross c832cb04e7 samd: add support for SAMD09 
The SAMD09 CPU is used in boards such as the Adafruit Seesaw. It has a
smaller amount of memory and flash than other SAMD ports.

This was tested with an Adafruit Seesaw. These boards come with preloaded
firmware. As a test, the firmware was dumped and flash was erased. Then,
flash was verified to be all zeroes. Finally, the firmware was loaded
back in:

Sean Cross d00607f71a samd: parameterize memory and flash sizes 
Various SAMD devices have different amounts of memory. Up until now, all
SAMD devices have had the same amount, and therefore this value was
hardcoded to 32k of RAM and 256k of flash.

Add a parameter to the description field and set it to default to the
previous values. Use this description field when adding memories to the
target definition.

Uwe Bonnes ac7c1057cc efm32/samd/samx5x: Remove static allocates strings. Allocate in priv_storage.

Uwe Bonnes dc3fd2eb06 Classify debug messages 
Firmware BMP with ENABLE_DEBUG=1 will print WARN and INFO as before.
PC-Hosted BMPwill alway print to stderr. Warn is printed unconditional,
INFO, GDB, TARGET, DONGLE and WIRE will print if their appropriate bit in
cl_debuglevel is set via the -v verbose command line argument.
INFO will go to stdout with -t or -l.

dpslwk 67f9d26644 samd: Add support for L21 & L22 (PR #345) 2019-11-09 13:59:37 +01:00
Uwe Bonnes 1cf0b8ac13 Make all arguments for all commands (struct *t, int argc, const char **argv). 
-Wall on gcc8 otherwise warns without -Wno-cast-function-type but older
GCCs/CLang choke on that argument:
error: unknown warning option '-Wno-cast-function-type'; did you mean
 '-Wno-bad-function-cast'? [-Werror,-Wunknown-warning-option]

This adds 24 byte to the binary, as some functions are now called with
additional dummy arguments:

Richard Meadows 600bc9f029 Generate DEBUG warnings and return if `malloc`/`calloc` fail. 
This is will make debugging earier if this does happen, rather than
dereferencing the null pointer (or passing it to memcpy, or worse).
