[bsp][tms320f28379d] Fix compile ti (#6254)

2022-08-20T17:16:41Z

* compile_ok Issues fixed: (1) update .config: select FINSH_USING_SYMTAB (2) add rt_size_t in rtconfig_project.h (3) fix finsh problems of using sym table (4) update .project to include ipc source codes. Todo list: (1) automate the build source selection of ccs and reconcile it with scons * change compiler * msh can run now the key step is to swap the order of rt_interrupt_nest -- and RT_OBJECT_HOOK_CALL(rt_interrupt_leave_hook,()) in irq.c. This is an improvised solution and an issue has been raised. * Update 2837x_FLASH_lnk_cpu1.cmd The original one is also fine. Just to make it more rigorous since FSymTab is in data section. * update readme.md Complier selection and maintainer update. Co-authored-by: YuQi

[libcpu][C28x] Fix bugs of old c28x interrupt api which can not save and restore int status

2019-06-18T12:59:00Z

In C28x DSP, interrupt status are stored in ST1 register. Both INTM and DBGM is used for masking interrupt, while the latter one is used in real-time debug mode. The origin function rudely enable and disable the interrupt without considering the recent interrupt status, which not only may cause problem in some situation but also is not in conformity with rt-thread design specifications. The new api will fix this bug.
