tms320f28379d fix init (#6343)

2022-08-29T19:35:23Z

解决 tms320f28379d bsp 启动的问题。主要改动如下。修正context.s中汇编代码错误。在旧版的代码中，操作数为32位而汇编命令却使用了针对16位数据的命令MOV，导致程序在某些情况无法正常启动线程。由于C28x的平台下，SP只支持16bit寻址，所以用于线程空间存放的heap以及ebss段都需要放在低16位的空间，针对这个问题修改了CMD文件。此外还增加基于CMD文件基于RAM的支持，方便调试。新增rtdef.h中RT_SECTION，RT_USED，ALIGN和RT_WEAK的定义。旧版bsp中这些定义为空，导致INIT_EXPORT注册的函数失效。修改程序启动代码，在程序入口直接调用原生启动代码以上改动在LAUNCHXL-F28379D 通过了测试。

[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
