* Remove CS3-style initialization.Marti Bolivar2012-04-111-5/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove libcs3-related bits from support/ld. Break them out into libmaple proper and Wirish as appropriate: vector table definition and ISR declarations go into libmaple proper, and startup code goes into Wirish. Vector table symbols are included into common.inc from an STM32 family-specific directory under support/ld/stm32. This is a combination of 5 commits. Individual commit messages follow: libcs3_stm32_src: Don't depend on cs3.h. So we can use the existing toolchain. Move ISR decls/vector table into libmaple proper. This allows us to configure the vector table on a per-family basis. - Move support/ld/libcs3_stm32_src/stm32_isrs.S stm32_vector_table.S to libmaple/stm32f1/isrs_performance.S vector_table_performance.S, respectively. The directory libmaple/stm32f1/ is intended to hold all STM32F1-specific code within libmaple. Obviously, there's a lot of work to do before this becomes true. - support/ld/libcs3_stm32_src/Makefile: Don't try to compile stm32_isrs.S and stm32_vector_table.S anymore. - Add libmaple/stm32f1/rules.mk to include these new files in the standard libmaple build. - support/make/target-config.mk: Add LIBMAPLE_MODULE_FAMILY, which selects a directory to use as a family-specific libmaple submodule. - Makefile: Add LIBMAPLE_MODULE_FAMILY to LIBMAPLE_MODULES. Remove support/ld/libcs3_stm32_src and derived object files. From support/ld/libcs3_stm32_src, move start.S and start_c.c into Wirish. Modify wirish/rules.mk accordingly. Delete support/ld/libcs3_stm32_*_density.a. These are no longer necessary, as the relevant objects are included in the standard Wirish build. Remove the GROUP statements from the board linker scripts accordingly. Remove SEARCH_DIR(.) from common.inc; it's no longer necessary. Also fix up some comments that are now out of date. wirish/start_c.c: Don't use CS3-style memory initialization. Switch memory initialization to a simpler style of initializing .data if necessary, then zeroing .bss. Initializing .data is only necessary during Flash builds, since during RAM builds, LOADADDR(.data) == ADDR(.data). This makes libmaple completely incompatible with the CS3 startup sequence. Subsequent commits will clean up the namespace to reflect that fact. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
* [support/ld] Unify linker scripts.Marti Bolivar2011-09-131-1/+3
| | | | | | | | | | | | | | | | 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.

still need usb descriptors to improve, and also nothing else is tested.
