imxrt:uart: Add PINs init for each uart port Add PINs init function based on the selected UART port. In general, user should configure all necessary PINs based on the specific imxrt board in: bsp/imxrt/xxxx/board/MCUX_Config/pin_mux.c There is a convenient GUI tool named MCUXpresso Config Tools, it's free and can be obtained from NXP offical website. Open the file: bsp/imxrt/imxrt1052-nxp-evk/board/MCUX_Config/MCUX_Config.mex with MCUXpresso Config Tools, set the necessary PINs (or clocks) and generate the new code of pin_mux.c (or clock_config.c), the project can get right configurations based on specific imxrt board. But, there is no relation between RT-Thread Kconfig and MCUXpresso Config Tools. User selects one driver in RT-Thread menuconfig, then the ping_mux.c should be udpated by MCUXpresso Config Tools to set the right PIN configurations for the selected driver. It's clear but a little complex. We add the PIN init functions for some drivers in the board.c file, 1. It's convenient to usr a driver in RT-Thread. Just select the driver, then the code will include all necessary parts, and the driver can work well. 2. User can also configure the PINs with MCUXpresso Config Tools. 3. The drivers in bsp/imxrt/libraries/drivers are common for all imxrt boards. They may have different PIN configurations based on different hardware design. So we put the PIN init functions in each board.c file following each different imxrt board. Signed-off-by: Gavin Liu <gavin-liugang@outlook.com>

imxrt:enet: Support imxrt ethernet interface 1. Add "drv_eth.c" for all imxrt platforms. 2. Add ksz8081 phy driver for imxrt1052-nxp-evk board. 3. Disable the LED demo in main.c file if enable the ENET and ksz8081 phy, because the PINs of LED and ksz8081 reset are from the same GPIO. 4. Update the relevant Kconfig and Sconscript files.

imxrt:uart: Add PINs init for each uart port Add PINs init function based on the selected UART port. In general, user should configure all necessary PINs based on the specific imxrt board in: bsp/imxrt/xxxx/board/MCUX_Config/pin_mux.c There is a convenient GUI tool named MCUXpresso Config Tools, it's free and can be obtained from NXP offical website. Open the file: bsp/imxrt/imxrt1052-nxp-evk/board/MCUX_Config/MCUX_Config.mex with MCUXpresso Config Tools, set the necessary PINs (or clocks) and generate the new code of pin_mux.c (or clock_config.c), the project can get right configurations based on specific imxrt board. But, there is no relation between RT-Thread Kconfig and MCUXpresso Config Tools. User selects one driver in RT-Thread menuconfig, then the ping_mux.c should be udpated by MCUXpresso Config Tools to set the right PIN configurations for the selected driver. It's clear but a little complex. We add the PIN init functions for some drivers in the board.c file, 1. It's convenient to usr a driver in RT-Thread. Just select the driver, then the code will include all necessary parts, and the driver can work well. 2. User can also configure the PINs with MCUXpresso Config Tools. 3. The drivers in bsp/imxrt/libraries/drivers are common for all imxrt boards. They may have different PIN configurations based on different hardware design. So we put the PIN init functions in each board.c file following each different imxrt board. Signed-off-by: Gavin Liu <gavin-liugang@outlook.com>

imxrt:enet: Support imxrt ethernet interface 1. Add "drv_eth.c" for all imxrt platforms. 2. Add ksz8081 phy driver for imxrt1052-nxp-evk board. 3. Disable the LED demo in main.c file if enable the ENET and ksz8081 phy, because the PINs of LED and ksz8081 reset are from the same GPIO. 4. Update the relevant Kconfig and Sconscript files.
