The console was not working on HP Moonshot (HPE Proliant Aarch64) because
the UART registers were accessed as 8-bit aligned addresses. However,
registers are 32-bit aligned for HP Moonshot.
Since ACPI/SPCR table does not specify the register shift to be applied to
the
register offset, this patch implements an erratum to correctly set the
register
shift for HP Moonshot.
Similar erratum was implemented in linux:

ACPI: SPCR: Workaround for APM X-Gene 8250 UART 32-alignment errata
APM X-Gene verion 1 and 2 have an 8250 UART with its register
aligned to 32-bit. In addition, the latest released BIOS
encodes the access field as 8-bit access instead 32-bit access.
This causes no console with ACPI boot as the console
will not match X-Gene UART port due to the lack of mmio32
option.

Any particular reason you offset this whole commit description by four spaces?
I get this effect when I use “git show” to look at a changeset for some reason.
Bhupinder, did you perhaps export a changeset as a patch using “git show” and
then re-import it?
In any case, this needs to be fixed.
Yes I copied the commit message from git show. I will align the text.
