dnl This ld script source is fed through m4 in order to fill in dnl those settings which depend on the configuration. dnl Memory region sizes are set in ../include/config.m4, generated dnl by the configuration mechanism based on the selected target, dnl and the Makefile prepends flash.m4 or xram.m4 to select the dnl type of image we are linking: either the regular flashable image, dnl or a RAM-only test image (to be loaded via fc-xram) that does not dnl touch the flash and pretends as if the flash doesn't even exist. /* * FreeCalypso ld script for the Buildmem build */ ENTRY(ifelse(Buildmem,XRAM,_FlashorXram_entry,0)) include(`../include/config.m4')dnl MEMORY { ifelse(Buildmem,FLASH, ` FLASH_OVERLAY : ORIGIN = 0, LENGTH = 0x2000 FLASH : ORIGIN = 0x2000, LENGTH = CONFIG_FWFLASH_SIZE - 0x2000') IRAM : ORIGIN = 0x00800000, LENGTH = CONFIG_IRAM_SIZE XRAM : ORIGIN = 0x01000000, LENGTH = CONFIG_XRAM_SIZE } ifelse(FFS_IN_RAM,1,` RAMFFS_BLKSIZE_BYTES = 1 << RAMFFS_BLKSIZE_LOG2; RAMFFS_TOTAL_SIZE = RAMFFS_BLKSIZE_BYTES * RAMFFS_NBLOCKS; ')dnl SECTIONS { /* XIP code, going into flash or XRAM emulating flash */ xip.text : { *(xip.text*) xipcode.o(.text*) *libplus.xip.a:(.text*) *librv.a:(.text*) *libsprintf.a:(.text*) /* let's put the ARM->Thumb veneers in the XIP section */ *(.glue_7) } > Buildmem /* copy-to-IRAM code */ iram.text 0x80001C : { /* the 7 exception and interrupt vectors @ 0x80001C */ *(iram.vectors) *(iram.text*) iramcode.o(.text*) *libplus.iram.a:(.text*) *libc.a:(.text*) *libgcc.a:(.text*) } > IRAM AT> Buildmem __iramtext_ram_addr = ADDR(iram.text); __iramtext_flash_addr = LOADADDR(iram.text); __iramtext_size = SIZEOF(iram.text); /* all .rodata will stay in flash */ .rodata : { *(.rodata*) } > Buildmem /* * All .data will go into XRAM. * For the flash build we'll have a step that copies * the .data section from flash to XRAM; for the RAM-only * build it goes directly into XRAM and stays there. */ .data : { *(.data*) } > XRAM AT> Buildmem ifelse(Buildmem,FLASH, ` __initdata_ram_addr = ADDR(.data); __initdata_flash_addr = LOADADDR(.data); __initdata_size = SIZEOF(.data); ')dnl /* we have two kinds of BSS: internal and external */ int.bss (NOLOAD) : { *(int.bss*) iramcode.o(.bss* COMMON) *libplus.iram.a:(.bss* COMMON) *libc.a:(.bss* COMMON) *libgcc.a:(.bss* COMMON) . = ALIGN(4); } > IRAM __intbss_start = ADDR(int.bss); __intbss_size = SIZEOF(int.bss); ext.bss (NOLOAD) : { *(ext.bss*) xipcode.o(.bss* COMMON) *libplus.xip.a:(.bss* COMMON) *librv.a:(.bss* COMMON) *libsprintf.a:(.bss* COMMON) . = ALIGN(4); } > XRAM __extbss_start = ADDR(ext.bss); __extbss_size = SIZEOF(ext.bss); /* finally, we have "raw RAM": like BSS, but we don't zero it out */ int.ram (NOLOAD) : { *(int.ram*) *(system_stack) *(irq_stack) *(fiq_stack) *(timer_hisr_stack) . = ALIGN(4); _iram_end = .; } > IRAM ext.ram (NOLOAD) : { *(ext.ram*) . = ALIGN(4); ifelse(FFS_IN_RAM,1, ` _RAMFFS_area = .; . += RAMFFS_TOTAL_SIZE; ')dnl _xram_end = .; } > XRAM }
