[posix] POSIX standard implementation for PSE51 (#5384) 
* [posix] POSIX standard implementation for PSE51

- add some posix's interfaces that we haven't before.
- these PR have passed the interface definition test across gcc platfrom;
- have tested base on qemu-a9 and stm32h750-art-pi.

* [newlib] only enable POSIX.1-1990

* update projects

T-HEAD SMART-EVB Introduction

SMART-EVB is a development board provided by T-HEAD, based on FPGA to provide implementation, integrating T-HEAD's RISC-V CPU (eg. E902/E906/C906) and C-SKY CPU (eg. E805/E804/E803/E802 ), integrates basic peripheral resources such as GPIO/TIMER/UART/RAM.

The main resources on board are as follows:

  1. SMART-EVB for T-Head CPU E9xx Series
res description
ISA RISCV
CPU E906
FREQ 20MHz
SRAM 768KB
  1. SMART-EVB for E804/E804F/E804D
res description
ISA C-SKY
CPU E804
FREQ 20MHz
SRAM 768KB

Compile T-HEAD BSP

SMART-EVB BSP supports GCC compiler, the version information is:

  1. SMART-EVB for E906/7/F/D/P
IDE/Compiler version
GCC gcc version 8.4.0 (C-SKY RISCV Tools V1.9.6 B20200616)
2. select cpu in rtconfig.py
3. scons -c; scons

Quick start with qemu

  1. download qemu wget https://occ-oss-prod.oss-cn-hangzhou.aliyuncs.com/resource/1356021/1612269502091/csky-qemu-x86_64-Ubuntu-16.04-20210202-1445.tar.gz
  2. qemu run qemu-system-riscv32 -cpu e906fdp -M smartl -kernel rtthread-e9xx.elf -nographic

Quick start with smart-evb

  1. Connect JTAG
  2. Connect the serial port
  3. riscv64-unknown-elf-gdb rtthread-e906f.elf
