Subject[RFT 12/16] memory: brcmstb_dpfe: Add separate entry for compile test
Date
Add separate entry for Broadcom STB DPFE driver, selected by platforms
by default. This allows further customization and compile testing.

Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>

I have other changes around drivers/memory/Kconfig pending. Sending them
together would avoid conflicts.

+ This driver provides access to the DPFE interface of Broadcom
+ STB SoCs. The firmware running on the DCPU inside the DDR PHY can
+ provide current information about the system's RAM, for instance
+ the DRAM refresh rate. This can be used as an indirect indicator
+ for the DRAM's temperature. Slower refresh rate means cooler RAM,
+ higher refresh rate means hotter RAM.
