在使用stm32的pwm驱动时，发现其初始化channel的时候是根据device->channel这个值去初始化的，device->channel这个值是在pwm_configh.h里面定义设置的，又根据rtt的pwm例程，和常规习惯，应该大多数人会更喜欢设置channel=1/2/3/4，而不是在pwm_configh.h中将channel设置为TIM_CHANNEL_1/2/3/4，因此建议drv_pwm.c做出PR中的修改。

在实际开发中，因pwm_configh.h的示例均是.channel=0，又没有做出解释说明要让.channel=TIM_CHANNEL_1/2/3/4的值，容易误操作导致没有成功输出PWM，这是我在实际开发中遇到的现实问题，因而提出此建议。

新增CH32V307的硬件定时器功能，并在CH32V307V-R1-1V0板卡上进行了测试。

[stm32f103-fire-arbitrary] support nandflash K9F1G08U0E && LPM init && partition create && partition read/write

[bsp][c28x] add support to not disable global interrupt in context-switch to enable zero-latency isr for critical interrupts.

如果打印格式为"%02X"的数据大于0x7F,打印的数据就会在前面多出6个'F',原因详见https://blog.csdn.net/zqxwce821/article/details/53011925。
现在通过强制转换成unsigned char后，在STM32（KEIL5+C99）已测试确认能修复该问题。

ARC: Minor port updates

In [1] we prefixed ARC Timer functions with "arc_"
and now we need to accommodate that change in RT-Thread
accordingly.

[1] https://github.com/foss-for-synopsys-dwc-arc-processors/embarc_bsp/commit/86a03d4bf99c8afad68c4c6a5941cda7a41dd4fe

In Python 3.x "print" is a function, not a command,
thus it requires braces around its arguments.

Otherwise build system fails to proceed.

* [bsp][ch32v307]添加了 pwm 驱动

1. 在c28x文件目录上一层再套一层文件夹ti，目前28379的项目路径为rt-thread\bsp\ti\c28x\tms320f28379d
2. 新增adc驱动与kconfig配置
