For various reasons (design, errata) boards may need to implement their

CONFIG_CFI_FLASH_USE_WEAK_ACCESSOR mark the functions as weak.  In the

Simon Glass aed2fbef5e dm: serial: Tidy up the pl01x driver
Adjust the driver so that leaf functions take a pointer to the serial port
register base. Put all the global configuration in the init function, and
use the same settings from then on.

This makes it much easier to move to driver model without duplicating the
code, since with driver model we use platform data rather than global
settings.

The driver is compiled with either the CONFIG_PL010_SERIAL or
CONFIG_PL011_SERIAL option and this determines the uart type. With driver
model this needs to come in from platform data, so create a new
CONFIG_PL01X_SERIAL config which brings in the driver, and adjust the
driver to support both peripheral variants.

Simon Glass fbb099183e dm: Convert spi_flash_probe() and 'sf probe' to use driver model
We want the SPI flash probing feature to operate as a standard driver.
Add a driver for the basic probing feature used by most boards. This
will be activated by device_probe() as with any other driver.

The 'sf probe' command currently keeps track of the SPI slave that it
last used. This doesn't work with driver model, since some other driver
or system may have probed the device and have access to it too. On the
other hand, if we try to probe a device twice the second probe is a nop
with driver model.

Fix this by searching for the matching device, removing it, and then
probing it again. This should work as expected regardless of other device
activity.
