Merge patch series "TI: AM64-EVM/SK: Enable MAIN UART1 for SYSFW tracing"
Vishal Mahaveer <[email protected]> says:
Collecting SYSFW traces from DMSC firmware is broken on the current
codebase. These changes enables MAIN_UART1 for collecting SYSFW traces
when the trace option is enabled in the boardcfg.
