When received a packet with an invalid length recorded in rx descriptor,
we should free this rx descriptor to allow us to continue to receive
following packets.
Without doing so, u-boot will stuck in a dead loop trying to process this
invalid rx descriptor.
This patch adds a call to mt7628_eth_free_pkt() after received an invalid
packet length.

The mt7628 has an embedded ethernet switch (5 phy ports + 1 cpu port).
Although in IOT mode only port0 is usable, the phy0 is still connected
to the switch, not the ethernet gmac directly.
This patch rewrites it and makes it optional. It can be turned on by adding
mediatek,poll-link-phy = <?> explicitly into the eth node. By default the
driver is switch mode with all 5 phy ports working without link detection.

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.

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

host controller interface are the following:
- Initiate the Host Controller Initialization process by writing to the
Host controller enable register.
- Configure the Host Controller base address registers by allocating a
host memory space and related data structures.
- Unipro link startup procedure
- Check for connected device
- Configure UFS host controller to process requests
Also register this host controller as a SCSI host controller.
