AM3358: UART basic example

Hi Anping,

From what I was able to find, l2_global_address() function is NOT used for AM335x device (do nothing). You can double check this if you run your UART example in step by step mode and check if your flow will enter into this function body and compute the addr or just exit doing nothing. You can also try to put HW breakpoint into this function and check the flow.

/**

static uintptr_t l2_global_address (uintptr_t addr)
{
#if defined(SOC_K2H) || defined(SOC_K2K) || defined(SOC_K2L) || defined(SOC_K2E) || defined(SOC_K2G) || defined(SOC_C6678) || defined(SOC_C6657) || \
    defined(DEVICE_K2H) || defined(DEVICE_K2K) || defined(DEVICE_K2L) || defined(DEVICE_K2E) || defined(DEVICE_K2G) || defined(DEVICE_C6678) || defined(DEVICE_C6657)

This function seems to be specific for DSP, while AM335x device do NOT have DSP.
