* [support/ld] Unify linker scripts.Marti Bolivar2011-09-1315-248/+89
| | | | | | | | | | | | | | | | Add new common.inc, which is common_rom.inc with some DEFINED(_FLASH_BUILD) usages thrown in to allow for RAM builds. It also uses a new REGION_RODATA region alias for read-only data. Move section .USER_FLASH to REGION_RODATA. This means it lives in RAM under RAM builds. Although this might be surprising, not doing so would make RAM builds useless. Modify the individual board linker scripts to properly set REGION_RODATA and _FLASH_BUILD before calling out to common.inc. Delete common_rom.inc, common_ram.inc, common_header.inc, in favor of common.inc. This should fix RAM builds on all boards.
* [support/ld] Put Maple Native's heap on external SRAM chip.Marti Bolivar2011-09-123-0/+12
| | | | | | Specify _lm_heap_start and _lm_heap_end in Maple Native's linker scripts to point respectively to beginning and end of FSMC-mapped external SRAM chip addresses.
* [support/ld] Add linker support for reconfigurable heap.Marti Bolivar2011-09-122-2/+16
| | | | | | | | | | | | | | | - common_header.inc: Declare EXTERN symbols _lm_heap_start and _lm_heap_end. - common_rom.inc: Check for _lm_heap_start and _lm_heap_end. If they are defined, preserve their values. Otherwise, _lm_heap_start is starts after .bss, and _lm_heap_end is the end of SRAM. This allows existing linker scripts to continue using the old heap scheme, but allows for customizability elsewhere. - syscalls.c: Respect the addresses of _lm_heap_start and _lm_heap_end as the boundaries of the heap in _sbrk().

* Linker scripts: Rename section targets.Marti Bolivar2011-09-092-14/+5
| | | | | | Use region aliases in common_ram.inc, common_rom.inc. These are provided by the individual board scripts which include these. Note that the aliases have horrible names. We'll need to fix that up.

* [support/ld] Factor out header from common_rom.inc, common_ram.inc.Marti Bolivar2011-09-073-73/+48
| | | | | | | The linker scripts share an initial section. Factor this out into a new file common_header.inc, and have the main linker scripts include this file. Apart from eliminating a redundancy, this will make it easier to add new linker scripts in the future.
* DMA: Fix non-working DMA interrupts.Marti Bolivar2011-06-201-7/+7
| | | | | | | | | | | | | | | | | | | | | | libmaple/dma.c defines DMA interrupts __irq_dma_channel[1-7], consistent with what is specified by support/ld/names.inc. However, names.inc is inconsistent with what support/ld/libcs3_stm32_src/ expects. Specifically, it contradicts the files - support/ld/libcs3_stm32_src/stm32_isrs.S - support/ld/libcs3_stm32_src/stm32_vector_table.S Which use the names __irq_dma1_channel[1-7]. Change names.inc and dma.c to use the correct IRQ names. The original names.inc/libcs3_stm32_src inconsistency was introduced in 43d6921658cd29b8022af4424d340a90fbcb9a7f, but dma.c had the correct names until ec3cf2903f4b03bc1dae5e159495c9e5ef0938ca, where they were renamed for consistency with names.inc. At that point, DMA interrupts stopped working. (This was documented in the commit message). Thanks to forum user robodude666 for tracking this down.
