Last time, I submitted a PR to enable UMS on lpi4a.
My idea is to perform GPIO detection before loading opensbi to determine whether to enter UMS mode.
This would make it convenient for operating on EMMC and enable a unified firmware flashing for both SD cards and EMMC.
However, I am currently unsure if the buttons on lpi4a have any reserved functionality, and I don't have information about the GPIO of the REC button (or any other button).
Do you have any thoughts or insights regarding these aspects?
