 * This is an adapted linker script from egcs-1.0.1

 *

 * Memory layout for an SH7045F with main memory in area 2

 * This memory layout it very similar to that used for Hitachi's

 * EVB with CMON in FLASH

 *

 * NOTE: The ram start address may vary, all other start addresses are fixed

 *       Not suiteable for gdb's simulator
