The RT_ASSERT(obj != object) line is only compiled for debug mode.
But the rt_enter/exit_critical causes the compiler not to optimize
at least these 2 calls, even if it could optimize out the whole loop,
because the rt_list_entry function has no side effect, and RT_ASSET
is a no-operation in release mode. So this patch fixes this:
- no warnings anymore
- better speed in release mode
* [bsp/nuvoton] Support NuMaker-M467HJ BSP and update drivers.
* Format files.
* [usbhost] List keyboard and update driver.
* Enlarge to reasonable thread stack size.
* Do indent..
* Keep private.

* 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

IAR new project defualt Processor mode is Thumb, this will cause user

* 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
