+@deffn {Flash Driver} xcf
+@cindex Xilinx Platform flash driver
+@cindex xcf
+Xilinx FPGAs can be configured from specialized flash ICs named Platform Flash.
+It is (almost) regular NOR flash with erase sectors, program pages, etc. The
+only difference is special registers controlling its FPGA specific behavior.
+They must be properly configured for successful FPGA loading using
+additional @var{xcf} driver command:
+
+@deffn Command {xcf ccb} <bank_id>
+command accepts additional parameters:
+@itemize
+@item @var{external|internal} ... selects clock source.
+@item @var{serial|parallel} ... selects serial or parallel data bus mode.
+@item @var{slave|master} ... selects slave of master mode for flash device.
+@item @var{40|20} ... selects clock frequency in MHz for internal clock
+in master mode.
+@end itemize
+@example
+xcf ccb 0 external parallel slave 40
@end example
+All of them must be specified even if clock frequency is pointless
+in slave mode. If only bank id specified than command prints current
+CCB register value. Note: there is no need to write this register
+every time you erase/program data sectors because it stores in
+dedicated sector.
+@end deffn
+
+@deffn Command {xcf configure} <bank_id>
+Initiates FPGA loading procedure. Useful if your board has no "configure"
+button.
+@example
+xcf configure 0
+@end example
+@end deffn
+
+Additional driver notes:
+@itemize
+@item Only single revision supported.
+@item Driver automatically detects need of bit reverse, but
+only "bin" (raw binary, do not confuse it with "bit") and "mcs"
+(Intel hex) file types supported.

+@deffn {Flash Driver} bluenrg-x
+STMicroelectronics BlueNRG-1 and BlueNRG-2 Bluetooth low energy wireless system-on-chip. They include ARM Cortex-M0 core and internal flash memory.
+The driver automatically recognizes these chips using
+the chip identification registers, and autoconfigures itself.
+
+@example
+flash bank $_FLASHNAME bluenrg-x 0 0 0 0 $_TARGETNAME
+@end example
+
+Note that when users ask to erase all the sectors of the flash, a mass erase command is used which is faster than erasing
+each single sector one by one.
+
+@example
+flash erase_sector 0 0 79 # It will perform a mass erase on BlueNRG-1
+@end example
+
+@example
+flash erase_sector 0 0 127 # It will perform a mass erase on BlueNRG-2
+@end example
+
+Triggering a mass erase is also useful when users want to disable readout protection.

+@deffn {Flash Driver} psoc6
+Supports PSoC6 (CY8C6xxx) family of Cypress microcontrollers.
+PSoC6 is a dual-core device with CM0+ and CM4 cores. Both cores share
+the same Flash/RAM/MMIO address space.
+
+Flash in PSoC6 is split into three regions:
+@itemize @bullet
+@item Main Flash - this is the main storage for user application.
+Total size varies among devices, sector size: 256 kBytes, row size:
+512 bytes. Supports erase operation on individual rows.
+@item Work Flash - intended to be used as storage for user data
+(e.g. EEPROM emulation). Total size: 32 KBytes, sector size: 32 KBytes,
+row size: 512 bytes.
+@item Supervisory Flash - special region which contains device-specific
+service data. This region does not support erase operation. Only few rows can
+be programmed by the user, most of the rows are read only. Programming
+operation will erase row automatically.
+@end itemize
+
+All three flash regions are supported by the driver. Flash geometry is detected
+automatically by parsing data in SPCIF_GEOMETRY register.
+
+PSoC6 is equipped with NOR Flash so erased Flash reads as 0x00.
+
+@example
+flash bank main_flash_cm0 psoc6 0x10000000 0 0 0 $@{TARGET@}.cm0

+psoc6-specific commands
+@deffn Command {psoc6 reset_halt}
+Command can be used to simulate broken Vector Catch from gdbinit or tcl scripts.
+When invoked for CM0+ target, it will set break point at application entry point
+and issue SYSRESETREQ. This will reset both cores and all peripherals. CM0+ will
+reset CM4 during boot anyway so this is safe. On CM4 target, VECTRESET is used
+instead of SYSRESETREQ to avoid unwanted reset of CM0+;
+@end deffn
+
+@deffn Command {psoc6 mass_erase} num
+Erases the contents given flash bank. The @var{num} parameter is a value shown
+by @command{flash banks}.
+Note: only Main and Work flash regions support Erase operation.
