Supreeth Venkatesh March 2, 2017, 10:26 p.m. UTC 
Server Base Boot Requirements (SBBR) specification is intended for SBSA-
compliant 64-bit ARMv8 servers.
It defines the base firmware requirements for out-of-box support of any
ARM SBSA-compatible Operating System or hypervisor.
The requirements in this specification are expected to be minimal yet
complete for booting a multi-core ARMv8 server platform, while leaving
plenty of room for OEM or ODM innovations and design details.
For more information, download the SBBR specification here:
http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.den0044b/index.html

This change introduces test cases as per SBBR specification to rsdp
acpi. These test cases may be subset/superset of rsdp acpi tests already
existing. However, to preserve "sbbr" classification, new file is
created, even when most of the code is re-used from acpi/rsdp.

I'm getting white space issues when I apply the patch:

Applying: sbbr/rsdp: Add initial rsdp acpi tests as per sbbr.
.git/rebase-apply/patch:120: space before tab in indent.
    	fwts_passed(fw, "SBBR: Structure of RSDP Table is consistent with
ACPI 6.0 or later and uses 64 bit xsdt addresses.");
.git/rebase-apply/patch:124: space before tab in indent.
    	fwts_failed(fw, LOG_LEVEL_CRITICAL,
.git/rebase-apply/patch:125: space before tab in indent.
    				"SBBR RSDP:",
.git/rebase-apply/patch:126: space before tab in indent.
    				"Structure of RSDP Table is not consistent with ACPI 6.0 or
later and/or does not use 64 bit xsdt addresses.");
warning: 4 lines add whitespace errors.

formatting has extra tabs, please clean that up.

I'd prefer if the comments in the code (and other patches) would match
the general fwts block style, e.g.

	/*
	 * This includes only the first 20 bytes of this table, bytes
	 * 0 to 19, including the checksum field. These bytes must
	 * sum to zero.
	 */

you don't need to initialize the above boolean

..and this one ^

please don't make const variables all caps. lowercase is the convention.

quite a long line, can it be less than 80 cols wide

this is better:

	checksum_pass = (checksum == 0);

space please between ) and ?

format the above as follows is preferred:

	if ((rsdp->xsdt_address != 0) &&
	    (rsdp->rsdt_address == 0))
		xsdt_address_pass = true;

The formatting style above needs reworking,

	if (( ... ) &&
	    ( ... ) &&
	    ....
	    ( ... ))
		fwts_passed(...)
	else
		fwts_failed(...)

Sorry, I may have messed up. Do you have recommendation like
patchcheck.py or something similar which checks style and whitespace
issues to check patches before sending it out?
