Subject: [PATCH] LF-484 tty: serial: lpuart: support UPIO_MEM32 for lpuart32
|
|
|
|
"earlycon" no need to specify the value string since it uses
|
|
stdout-path parameters. However when earlycon and normal console
|
|
are not using the same uart port, we need specify value string
|
|
to earlycon, this is what we need to do when support dual linux
|
|
using jailhouse hypervisor. The 2nd linux will use the uart
|
|
of the 1st linux as earlycon.
|
|
|
|
earlycon=lpuart32,mmio32,0x5a060010,115200 not work for i.MX8QXP.
|
|
It is because lpuart32_early_console_setup not support little endian.
|
|
|
|
Since the original code is to support UPIO_MEM32BE, so if not
|
|
UPIO_MEM32, we still take it as UPIO_MEM32BE
