There are two other drivers that bind to "mrvl,mmp-uart": the 8250_of and the 8250_pxa. The previous one is generic and the latter is binded to ARCH_PXA || ARCH_MMP. Now we may have pxa programming compatible HW to support, making use of the generic 8250_of seems a good idea. However, there's no earlycon support if we go with this solution. So move the mmp|pxa-uart earlycon code to core 8250_early.c. patch2 adds xscale earlycon support too, only build test since I have no xscale machine any more. Since v1: - split the patch into two as suggested by Greg Jisheng Zhang (2): serial: 8250: move mmp|pxa uart earlycon code serial: 8250_early: add xscale earlycon support drivers/tty/serial/8250/8250_early.c | 11 +++++++++++ drivers/tty/serial/8250/8250_pxa.c | 16 ---------------- 2 files changed, 11 insertions(+), 16 deletions(-) -- 2.43.0
