If the application defines dozens of global variables,
the speed of clearing the bss segment will be slower.
Because icache can be enabled before the mmu enabled.
Therefore, in order to speed up the process of clearing the BSS segment,
enable icache needs to be put ahead.
* bsp beaglebone: add IAR template files and fix it's build error
ATTENTION:
project.* was generated by scons, so I add it to gitignore.
rtconfig.py *FLAGS located in "PLATFORM == 'iccarm'" are unverified and maybe wrong.
（我只是从STM32里面抄来，然后根据自己的理解改了一下，并没有验证这些参数的正确性，
我也不知道怎么用命令行调用这些参数来编译）
* bsp beaglebone: add beaglebone_ram.icf ROM address from uboot_cmd.txt
am335x_DDR.icf use 0x82000000, different to uboot_cmd.txt & gcc beaglebone_ram.lds,
the difference will easy cause later developer got below error:

* bsp beaglebone: change IAR template.ewp code use Arm mode
Arm mode bin size will bigger than Thumb mode
* libcpu am335x: IAR: use rt_hw_cpu_dcache_enable instead of rt_cpu_dcache_enable
Reviewer mysterywolf say:
麻烦把rt_cpu_icache_enable 和 rt_cpu_dcache_enable, 统一改成 rt_hw_cpu_icache_enable 和 rt_hw_cpu_dcache_enable
rt_hw_cpu_icache_enable 和 rt_hw_cpu_dcache_enable 是其他bsp也是这么命名的 这是个命名统一的函数
* bsp beaglebone: rerun menuconfg
* bsp beaglebone: add uart0 support
* bsp beaglebone: use uart0 as console
* bsp beaglebone: add heap init
fix rt_application_init() error:
(m != RT_NULL) assertion failed at function:rt_smem_alloc, line number:288
* bsp beaglebone: add mmu & interrupt init
must init mmu, otherwise no interrupt is generated, cause scheduler can't work.
I don't know why need mmu, just seen: bsp/rockchip/rk3568/driver/board.c
* libcpu am335x: reset interrupt controller before init vector
I think reset before init is more better

* bsp beaglebone: full gpio driver support
* bsp beaglebone: add tftpboot way to uboot_cmd.txt
* bsp beaglebone: optimize am33xx_gpio_hdr, check irqstatus is the last one

* 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.

使用不同的优化等级会出现不同的效果
当使用-O0 等级时，无法正确得到关闭中断之前的状态
Using different optimization levels will have different effects
When the - o0 level is used, the state before the shutdown interrupt cannot be obtained correctly
