functions and a file for mt7628 which has additional support for pinconf.

Currently this driver uses a different way to implement the spi xfer,
by modifying some fields of two registers, which is incompatible with the
MTK's original SDK linux driver. This will cause the flash data being
damaged by the SDK driver.
This patch lets the mt7621_spi_set_cs() restore the original register
fields after cs deactivated.

The mt7621 spi controller supports continuous generic half-duplex spi
transaction. There is no need to cache xfer data at all.
To achieve this goal, the OPADDR register must be used as the first data
to be sent. And follows the eight generic DIDO registers. But one thing
different between OPADDR and DIDO registers is OPADDR has a reversed byte
order.
With this patch, any amount of data can be read/written in a single xfer
function call.

All three UARTs of mt7628 are actually MediaTek's high-speed UARTs which
support baudrate up to 921600.
The high-speed UART is compatible with ns16550 when baudrate <= 115200.
Add compatible string to dtsi file so u-boot can use it when serial_mtk
driver is built in.

The UART of MT7628 has fixed 40MHz input clock so there is no need to put

The current brcmnand driver is based on 4.18 linux kernel which uses
mtd_set_ooblayout to set ecc layout. But nand base code in u-boot is from
old kernel which does not use this new API and expect nand_chip.ecc.layout
structure to be set. This cause nand_scan_tail function running into a bug
check if the device has a different oob size than the default ones.
This patch ports the brcmstb_choose_ecc_layout function from kernel 4.6.7
that supports the ecc layout struture and replaces the mtd_set_ooblayout
method

The ULP has two USB controllers. These two controllers have similar NC
registers layout as i.MX7D. But OTG0 uses UTMI PHY simliar as i.MX6, not
the integrated PHY on i.MX7D. The OTG1 needs off-chip HSIC PHY or ULPI PHY
to work.
This patch only supports OTG0 with UTMI PHY.

This fixes the issues with calculation of controller indexes in
ehci_usb_bind() for iMX7, as USB controllers on iMX7 SoCs aren't
placed next to each other, and their addresses incremented by 0x10000.
Example of USB nodes for iMX7S/D:
usbotg1: usb@30b10000 {
compatible = "fsl,imx7d-usb", "fsl,imx27-usb";
reg = <0x30b10000 0x200>;
^^^^^^^^^^
....
usbotg2: usb@30b20000 {
compatible = "fsl,imx7d-usb", "fsl,imx27-usb";
reg = <0x30b20000 0x200>;
^^^^^^^^^^
....
usbh: usb@30b30000 {
compatible = "fsl,imx7d-usb", "fsl,imx27-usb";
reg = <0x30b30000 0x200>;
^^^^^^^^^^
....
Which was leading to usb enumeration issues:
Colibri iMX7 # usb start
starting USB...
Bus usb@30b10000: USB EHCI 1.00
Bus usb@30b20000: probe failed, error -22
scanning bus usb@30b10000 for devices... 1 USB Device(s) found

All platforms which are using MANUAL_RELOC are jumping back to origin
