This patch adds support to legacy serial for
UARTS with shifted registers.
The MVME5100 Single Board Computer is a PowerPC platform
that has 16550 style UARTS with register addresses that are
16 bytes apart (shifted by 4).
Commit 309257484c
"powerpc: Cleanup udbg_16550 and add support for LPC PIO-only UARTs"
added support to udbg_16550 for shifted registers by adding a "stride"
parameter to the initialisation operations for Programmed IO and
Memory Mapped IO.
As a consequence it is now possible to use the services of legacy serial
to provide early serial console messages for the MVME5100.
An added benefit of this is that the serial console will always be
"ttyS0" irrespective of whether the computer is fitted with extra
PCI 8250 interface boards or not.
I have tested this patch using the four PowerPC platforms available to me:
MVME5100 - shifted registers,
SAM440EP - unshifted registers,
MPC8349 - unshifted registers,
MVME4100 - unshifted registers.

If you say yes to this option, support will be included for the
|
|
USB Gecko adapter as an udbg console.
|
|
The USB Gecko is a EXI to USB Serial converter that can be plugged
|
|
into a memcard slot in the Nintendo GameCube/Wii.
|
|
|
|
This driver bypasses the EXI layer completely.
|
|
|
|
If in doubt, say N here.
