2018-10-16rtos: check symbol list when updating uCOS-IIISteven Stallion1-0/+5
This patch corrects a crash in uCOS-III on a new GDB connection when RTOS autodetection is not used. The crash was caused by not checking if the symbol list had been loaded prior to updating threads.

2018-10-16esirisc: support eSi-RISC targetsSteven Stallion1-0/+14
eSi-RISC is a highly configurable microprocessor architecture for embedded systems provided by EnSilica. This patch adds support for 32-bit targets and also includes an internal flash driver and uC/OS-III RTOS support. This is a non-traditional target and required a number of additional changes to support non-linear register numbers and the 'p' packet in RTOS support for proper integration into EnSilica's GDB port.

2018-10-16rtos: support gdb_get_register_packetSteven Stallion1-2/+4
This patch adds support for p packet responses by targets configured with RTOS support. This change required moving to a rtos_reg struct, which is similar to struct reg used by targets, which resulted in needing to update each stacking with register numbers. This patch also allows targets with non-linear register numbers to function with RTOSes as well.

2017-06-30rtos: better sanity checking for uCOS-IIISteven Stallion1-0/+5
This patch improves the OSRunning check. If the rtos_running check fails, update_threads will return an error rather than attempt to update the thread list using bad values.

2017-06-30rtos: style corrections for uCOS-IIISteven Stallion1-68/+65
This patch corrects a number of style infractions in RTOS support for uC/OS-III. These were missed during initial review last year prior to the 0.10.0 release.

2016-12-08rtos: add support for uC/OS-IIISteven Stallion1-0/+509
This patch introduces RTOS support for uC/OS-III. Currently, only FPU-less ARM Cortex-M targets are supported. Due to the configurability of the RTOS, an OpenOCD-specific file must be linked along with the project to determine the correct offsets within the OS_TCB structure. In addition to the above, a crash was fixed in rtos_get_gdb_reg_list such that RTOS support could be used between resets without restarting OpenOCD and support for the Hg packet was cleaned up.
