Subject: [PATCH v4 0/5] spi: spi-mem: Add driver for NXP FlexSPI
controller

- Add driver for NXP FlexSPI host controller

 FlexSPI is a flexsible SPI host controller [1], Chapter 30 page
1475,  which supports two SPI channels and up to 4 external devices.
 Each channel supports Single/Dual/Quad/Octal mode data transfer
(1/2/4/8 bidirectional data lines)  i.e. FlexSPI acts as an
interface to external devices, maximum 4, each with up to 8  bidirectional

data lines.

- Tested this driver with mtd_debug(Erase/Write/Read) utility and
JFFS2 filesystem mounting and booting on NXP LX2160ARDB[2] and
LX2160AQDS targets.
 LX2160ARDB is having two NOR slave device connected on single bus A
i.e. A0 and A1 (CS0 and CS1).
 LX2160AQDS is having two NOR slave device connected on separate
buses  one flash on A0 and second on B1 i.e. (CS0 and CS3).
 Verified this driver on following SPI NOR flashes:
   Micron, mt35xu512aba[3], [Read - 1 bit mode]
   Cypress, s25fl512s, [Read - 1/2/4 bit mode]
