In the case of Cortex-A, compile error occurs in critical.c

[TomoYamanaka]

Hi.

In the following mbed SDK
  https://github.com/mbedmicro/mbed

You implemented critical.c. In this file, "__get_PRIMASK()" is referenced.
However, "__get_PRIMASK()" is a function that is supported only on Cortex-M.
"__get_PRIMASK()" is not supported in Cortex-A.
Therefore, the compile error occurs in Cortex-A.

Reference: #1804, and more...

Regards,
Yamanaka
