generated from vivado and from bootgen. With this new change in
Xilfpga, uboot doesn't need to validate and swap bitstream as it will
be taken care inside Xilfpga. ZynqMP PL driver now checks for supporting
PMUFW version before skipping the validation and swap sequence as there
can be old PMUFW which doesn't supports this feature. In this case, driver
uses old way of PL bitstream loading sequence.

The loop in ahci_start_ports() is looping over the maximum number of
SCSI devices in the system, which can be larger than the amount of ports
a particular AHCI controller has. The extra looping isn't directly
harmful because the link_port_map bitmap won't have the bit set for a
nonexistent port, but it is wasteful. Replace the loop limit with the
port count of the AHCI controller instead.

On some boards using TI CPSW, it may be possible that
PHY address was not latched correctly, and the actual

Some MTD sublayers/drivers are implementing ->_read/write() and
not ->_read/write_oob().
While for NAND devices both are usually valid, for NOR devices, using
the _oob variant has no real meaning. But, as the MTD layer is supposed
to hide as much as possible the flash complexity to the user, there is
no reason to error out while it is just a matter of rewritting things
internally.
Add a fallback on mtd->_read() (resp. mtd->_write()) when the user calls
mtd_read_oob() (resp. mtd_write_oob()) while mtd->_read_oob() (resp.
mtd->_write_oob) is not implemented. There is already a fallback on the
_oob variant if the former is used.

Unlike what's done in mtd_read/write(), there are no checks to make sure
the parameters passed to mtd_read/write_oob() are consistent, which

Do general sanity checks, like ops fields consistency and range checking.
