These should be u8 after all, right? Wait, status is a bool in the end:
while ((status = !litex_read8(membase + OFF_RXEMPTY)) == 1) {
But why is it passed to uart_insert_char() as such? That's ugly. Maybe drop all of this "status" and pass LSR_RXC directly. The while's condition would simply look like (!litex_read8(membase + OFF_RXEMPTY)) then.
ch = litex_read8(membase + OFF_RXTX);
