build-system: include soc_caps defines into kconfig Adds gen_soc_caps_kconfig.py which parses the soc caps (soc_caps.h) into a format that can be included in kconfig. 2021-11-05 05:23:24 -04:00			`#####################################################`

newlib: Add workaround for printf functions using 32-bit time_t on first call sizeof(time_t) was previously switched from 4 to 8, ROM functions that use time_t or dependent types (such as "struct stat") are no longer called due as they still treat sizeof(time_t) as 4 (see commit 24c20d188e24c815e28351cddb838c01e7dfb241). However, there is a ROM callpath that was left out. If putchar is the first stdio print related call, the call path will result in cantwrite() -> __swsetup_r() -> __smakebuf_r() -> __swhatbuf_r() using the ROM "struct stat" (where sizeof(time_t)==4). Instead of removing all printf related ROM newlib functions (which will result in increased binary size), this commit adds a workaround to setup the stdio files before any print related calls occur. This results in cantwrite() always returning false, thus the callpath described above never being reached. Closes https://github.com/espressif/esp-idf/issues/9269 2022-08-18 09:23:53 -04:00
