Add the DT nodes required to probe the CFI compatible parallel monitor flash found on the Malta development board, and remove the platform code that was previously doing it. Delete the now-empty malta-platform.c file. Adjust the Malta defconfigs that enable MTD & the pflash/CFI driver to enable CONFIG_MTD_PHYSMAP_OF rather than CONFIG_MTD_PHYSMAP in order to preserve their behaviour.

|
|
* 1. Probe driver for the Malta's UART ports:
|
|
*
|
|
* o 2 ports in the SMC SuperIO
|
|
* o 1 port in the CBUS UART, a discrete 16550 which normally is only used
|
|
* for bringups.
|
|
*
|
|
* We don't use 8250_platform.c on Malta as it would result in the CBUS
|
|
* UART becoming ttyS0.
|
|
*
|
|
* 2. Register RTC-CMOS platform device on Malta.
