CONFIG_ARMV7_M_ARMV8_M_MAINLINE
¶
(No prompt – not directly user assignable.)
Type: bool
Help¶
This option signifies the use of an ARMv7-M processor implementation, or the use of a backwards-compatible ARMv8-M processor implementation supporting the Main Extension.
Notes: - A Processing Element (PE) with the Main Extension is also referred to as a Mainline Implementation. - ARMv7-M compatibility requires the Main Extension.
From https://developer.arm.com/products/architecture/m-profile: The Main Extension provides backwards compatibility with ARMv7-M.
Defaults¶
