Remove CS3-style initialization.
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fix up some comments that are now out of date.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.
