Single port migrate to multi port Guide

[sakumisu]

Device

• add CONFIG_USBDEV_MAX_BUS macro, and only hpm can be 2, others should be 1.

#define CONFIG_USBDEV_MAX_BUS 1

• every api add uint8_t busid, and no use if CONFIG_USBDEV_MAX_BUS=1

• USBD_BASE macro remove, use usbd_initialize instead.

usbd_initialize(0, USBD_BASE, usbd_event_handler)

• USBD_IRQHandler macro remove, call USBD_IRQHandler(xxx) in your actual irq name, for example

void USBD_IRQ(void)
{
    extern void USBD_IRQHandler(uint8_t busid);
    USBD_IRQHandler(0);
}

Host

• add CONFIG_USBHOST_MAX_BUS macro

#define CONFIG_USBHOST_MAX_BUS 1

• USBH_BASE macro remove, use usbh_initialize instead.

usbh_initialize(0, USBH_BASE)

• USBH_IRQHandler macro remove, call USBH_IRQHandler(xxx) in your actual irq name, for example

void USBH_IRQ(void)
{
    extern void USBH_IRQHandler(uint8_t busid);
    USBH_IRQHandler(0);
}
