commit 210b7d2d1644c5c3dd1e59ffa684af56e3be498f
Author: Marc Schink <de...@za...>

flash/nor/stmqspi: Replace macros with static inline functions
There is no good reason to use macros instead of static inline functions. The
current code is hard maintain. For example, it changes variables outside of the
macro scope. Also, it is conflicting with the C coding style.

stlink: swo: use completely the available buffer
The buffer passed to stlink_usb_trace_read() is allocated of size
*size and does not need to be zero-terminated. There is no reason
to not fill its last byte.
When checking the bytes available on swo, limit the retrieved byte
length to *size.
