/* These are the newlib functions present in ESP32 ROM.
7+
They should not be used when compiling with PSRAM cache workaround enabled.
8+
See also esp32.rom.newlib-data.ld for the list of .data/.bss symbols
9+
used by these functions, and esp32.rom.newlib-nano.ld for "nano" versions
10+
of printf/scanf family of functions.
11+
12+
Unlike other ROM functions which are exported using PROVIDE, which declares
13+
weak symbols, newlib related functions are exported using assignment,
14+
which declares strong symbols. This is done so that ROM functions are always
15+
used instead of the ones provided by libc.a.
16+
17+
Time functions were moved to the esp32.rom.newlib-time.ld file.
