This commit deprecates the "freertos/xtensa_context.h" and "xtensa/xtensa_context.h" include paths. Users should use "xtensa_context.h" instead. - Replace legacy include paths - Removed some unnecessary includes of "xtensa_api.h" - Add warning to compatibility header

|
|
* is being injected into various memory regions which produces
|
|
* EXCCAUSE_ILLEGAL on execution attempt. Such a result is expected
|
|
* but it causes system reboot in the standard panic handler.
|
|
* The following variant of panic handling simply returns back to the
|
|
* next instruction and continues normal execution.
|
|
*
|
|
* NOTE: if EXCCAUSE_ILLEGAL comes from a different source than the testing code
|
|
* the behavior is undefined
