[PATCH V2 soc/next?] ARM: BCM53573: Initial support for Broadcom BCM53573 SoCs

[zajec5@gmail.com (Rafał Miłecki)]

From: Rafa? Mi?ecki <rafal@milecki.pl>

BCM53573 series is a new family with embedded wireless. By marketing
people it's sometimes called Northstar but it uses different CPU and has
different architecture so we need a new symbol for it.
Fortunately it shares some peripherals with other iProc based SoCs so we
will be able to reuse some drivers/bindings.

V2: Put new symbol under "Other Architectures"
