@deffn {Flash Driver} w600
W60x series Wi-Fi SoC from WinnerMicro
are designed with ARM Cortex-M3 and have 1M Byte QFLASH inside.
The @var{w600} driver uses the @var{target} parameter to select the
correct bank config.
@example
flash bank $_FLASHNAME w600 0x08000000 0 0 0 $_TARGETNAMEs
@end example
@end deffn
@deffn {Flash Driver} xmc1xxx @deffn {Flash Driver} xmc1xxx
All members of the XMC1xxx microcontroller family from Infineon. All members of the XMC1xxx microcontroller family from Infineon.
This driver does not require the chip and bus width to be specified. This driver does not require the chip and bus width to be specified.
