* Major changes in Chopstx 1.15
Released 2019-05-10
Released 2019-05-1X
** SYS version 4.0
USB initialization/finalization demarcation has been changed.
Enabling/disabling USB module is done by USB driver. SYS routines
only handles USB cable config. If a board has a fixed pull-up
resistor, USB driver can omit calling
usb_lld_sys_init/usb_lld_sys_shutdown.
only handles USB cable config. For all boards, USB driver doesn't use
usb_lld_sys_init/usb_lld_sys_shutdown (those routines only makes sense
for USB self powered situation, which Chopstx does not support yet).
** USB driver change
Enabling/disabling USB module is done by USB driver. Only with
-DUSE_SYS option, it calls usb_lld_sys_init/usb_lld_sys_shutdown.
Don't forget having -DUSE_SYS to support boards with non-fixed 1K5
resistor. Despite this change, it should work well with SYS 3.0
routines.
Enabling/disabling USB module is done by USB driver. It's
responsibility of board configuration to enable external transistor
for pull-up D+-line.
** Board configuration change
For USB driver change, board-maple-mini.h, board-olimex-stm32-h103.h,
board-stbee.h, and board-stm32-primer2.h were changed.
** Cortex-M4 support
Cortex-M4 support has been added. Not supporting use of FPU or DSP,
