William Zhang 55c0144bd3 spi: bcmbca-hsspi: Add driver for newer HSSPI controller 
The newer BCMBCA SoCs such as BCM6756, BCM4912 and BCM6855 include an
updated SPI controller that add the capability to allow the driver to
control chip select explicitly. Driver can control and keep cs low
between the transfers natively. Hence the dummy cs workaround or prepend
mode found in the bcm63xx-hsspi driver are no longer needed and this new
driver is much cleaner.

menuconfig SPI
bool "SPI Support"
help
The "Serial Peripheral Interface" is a low level synchronous
protocol. Chips that support SPI can have data transfer rates
up to several tens of Mbit/sec. Chips are addressed with a
controller and a chipselect. Most SPI slaves don't support
dynamic device discovery; some are even write-only or read-only.
SPI is widely used by microcontrollers to talk with sensors,
eeprom and flash memory, codecs and various other controller
chips, analog to digital (and d-to-a) converters, and more.
MMC and SD cards can be accessed using SPI protocol; and for
DataFlash cards used in MMC sockets, SPI must always be used.
SPI is one of a family of similar protocols using a four wire
interface (select, clock, data in, data out) including Microwire
(half duplex), SSP, SSI, and PSP. This driver framework should
work with most such devices and controllers.
if SPI
config DM_SPI
bool "Enable Driver Model for SPI drivers"
depends on DM
help
Enable driver model for SPI. The SPI slave interface
(spi_setup_slave(), spi_xfer(), etc.) is then implemented by
the SPI uclass. Drivers provide methods to access the SPI
buses that they control. The uclass interface is defined in
include/spi.h. The existing spi_slave structure is attached
as 'parent data' to every slave on each bus. Slaves
typically use driver-private data instead of extending the
spi_slave structure.

help
Enable this option if you want to enable the SPI memory extension.
This extension is meant to simplify interaction with SPI memories
by providing an high-level interface to send memory-like commands.
config SPI_DIRMAP
bool "SPI direct mapping"
depends on SPI_MEM
help
Enable the SPI direct mapping API. Most modern SPI controllers can
directly map a SPI memory (or a portion of the SPI memory) in the CPU
address space. Most of the time this brings significant performance
improvements as it automates the whole process of sending SPI memory
operations every time a new region is accessed.
