7f307423c1 newlib: Provide library name for ROM libc object files linked as PSRAM workarounds
Works around bug reported on forums where any source file ending in *lock.c or *creat.c
was being linked to IRAM.

https://esp32.com/viewtopic.php?f=13&t=8909&p=37362#p37362

Also moves all related functionality to newlib component.

8deb885ce3 newlib: disable some optimizations for syscalls.c
Don’t allow the compiler to convert malloc + memset into calloc,
causing a recursive call in _calloc_r. Fixes crash when building with
-O2 optimization level.

9903ea1c11 Add --warn-undefined-variables to MAKEFLAGS
Fix warnings where undefined vars are used.

Make Kconfig emit "FOO=" for unset bool options
To ensure make variables are always defined, even if empty.

When writing auto.conf, include symbols disabled by dependency to make sure all make variables are always defined.

Fixes espressif/esp-idf#137

Cherry-picked from https://github.com/espressif/esp-idf/pull/138

34372a091c Add initial SPI RAM support. This adds support for an ESP-PSRAM32 chip connected to the default flash pins and GPIO 16 and 17. The RAM is mapped to address 0x3F800000, but otherwise ignored by esp-idf as of yet. 2017-09-04 12:05:49 +08:00

d664e32394 build system: Use component.mk for all components, refactor bootloader build
For config-only components, component.mk should now contain "COMPONENT_CONFIG_ONLY := 1"

Also refactored some of the generation of linker paths, library list. This required cleaning up the way the bootloader
project works, it's now mostly independent from the parent.

221dc13535 newlib: add "full" formatting support, add missing functions
- add two versions of libc: libc.a and libc_nano.a. First one has full C99 formatting support, second one uses “nano” formatting functions available in ROM.
- fix linker error for fmod, fmodf, atof, atoff
- update tests

208e83def7 build system: Refactor component.mk to not need component_common.mk
New makefile component_wrapper.mk allows some variables to be set
before component.mk is evaluated. This properly fixes problems with
sdkconfig being hard to access in all phases of the build.

Including component_common.mk is no longer necessary and will print a
deprecation warning for components which use it.

830e5caf4d build system: Replace get_variable target w/ component_project_vars.mk generated makefiles
Reduces number of make invocations, allows variables exported in project
to be seen in all component make processes, not just the main ones.

Also makes a no-op build about 3x faster than it was.

- spaces->tabs in tasks.c
- update vfs_uart.c to use per-UART locks

3b1c3dab4b Name component makefiles component.mk instead of Makefile
Fixes problems with Eclipse trying to build in directories it shouldn't.

This is a breaking change for existing repositories, they need to rename
any component Makefiles to component.mk and rename their references to
$(IDF_PATH)/make/component.mk to $(IDF_PATH)/make/component_common.mk

Renamed from components/newlib/Makefile (Browse further)
