* Description:
* Common linker script configuration options.
*
* There are three supported memory layouts for the ARMv7-M architecture:
*
* Layout 1 - Single region:
* This layout uses a single read/write/execute memory region for all data.
* This is traditionally used by firmware running from a general-purpose
* RAM region. In this configuration MEM0 represents the RAM region, and
* MEM1 is unused.
*
* Layout 2 - Dual region with relocation:
* This layout uses a read/execute memory region for read-only and
* executable data, and a write memory region for writable data. This is
* traditionally used by firmware running from a ROM region. In this
* configuration MEM0 represents the ROM region and MEM1 represents the RAM
* region.
*
* Layout 3 - Dual region without relocation:
* This layout uses an execute memory region for executable data, and a
* read/write memory region for writable data. This is traditionally used
* by firmware running from a RAM region attached to the instruction bus.
* In this configuration MEM0 represents the RAM region attached to the
* instruction bus and MEM1 represents the RAM region attached to the data
* bus.
