Ye Li def88bce09 spi: fsl_qspi: Support to use full AHB space on i.MX 
i.MX platforms provide large AHB mapped space for QSPI, each
controller has 256MB. However, current driver only maps small
size (AHB buffer size) of AHB space, this implementation
causes i.MX failed to boot M4 with QSPI XIP image.

Add config CONFIG_FSL_QSPI_AHB_FULL_MAP (default enabled for i.MX)
to address above problem.

When the config is set:
1. Full AHB space is divided to each CS.
2. A dedicated LUT entry is used for AHB read only.
3. The MODE instruction in LUT is replaced to standard ADDR instruction
4. The address in spi_mem_op is used to SFAR and AHB read

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.

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.
