This patch should be applied on top of the patchset
"MIPS: OCTEON: flash: syncronize bootbus access"
https://lkml.kernel.org/g/<1419337623-16101-1-git-send-email
ented differently.
Now the code uses the existing match() member of struct console.
It has already been implemented for 8250.
Probably SPCR table specifies incorrect data.
It was reported that D02 board has similar issue.

We have multiple "earlycon" early_param handlers - merge the DT one into
the main earlycon one. It's a cleanup that also will be useful
to decide if ACPI SPCR earlycon should be set up.

This patch adds function pl011_console_match() that implements
method match of struct console. It allows to match consoles against
data specified in a string, for example taken from command line or
compiled by ACPI SPCR table handler.

Instead, pass the sideband data specified by the driver.
- Fix the driver's callback signatures: a. Add an unused pointer to void
for table matchers (currently only clocksource callback) b. Change
the type of sideband data to kernel_ulong_t.

the decision on whether to attempt ACPI configuration into the
early_param handling. Then make acpi_boot_table_init() bail out if
