* Major changes in Chopstx 0.11
Released 2016-0X-XX
** FS-BB48: Kinetis L MCU
Support for FS-BB48 board with Kinetis L MCU is added.
** No HardFault at context switch on Cortex-M0
By its design, Chopstx does context switch hodling scheduler lock.
This is implemented with the feature of BASEPRI on Cortex-M3. Because
Cortex-M0 doesn't have support of BASEPRI, the context switch (before
version 0.11) always caused HardFault exception. Since Cortex-M0
doesn't have complex exception mechism of ICI/IT (which is supported
on Cortex-M3), it is actually possible to implement the context switch
in user mode. This is done.
