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:
=> go 0x80200000

* libcpu am335x: context_iar.S rt_hw_context_switch: add thumb mode support
IAR new project defualt Processor mode is Thumb, this will cause user
easy occur the following 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
AM335X_StarterWare_02_00_01_01\system_config\armv7a\am335x\interrupt.c
IntAINTCInit()
* 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
