flash/nor: Add PSoC 5LP flash driver
Always probe for ECC mode and display ECC sectors if disabled. Non-ECC write is implemented as zeroing the ECC/config bytes. Erasing ECC sectors is ignored, erase-checking takes them into account. Tested with CY8CKIT-059 (CY8C5888), except ECC mode.

@deffn {Flash Driver} psoc5lp
|
||||||
|
All members of the PSoC 5LP microcontroller family from Cypress
|
||||||
|
include internal program flash and use ARM Cortex-M3 cores.
|
||||||
|
The driver probes for a number of these chips and autoconfigures itself,
|
||||||
|
apart from the base address.
|
||||||
|
|
||||||
|
@example
|
||||||
|
flash bank $_FLASHNAME psoc5lp 0x00000000 0 0 0 $_TARGETNAME
|
||||||
|
@end example
|
||||||
|
|
||||||
|
@b{Note:} PSoC 5LP chips can be configured to have ECC enabled or disabled.
|
||||||
|
@quotation Attention
|
||||||
|
If flash operations are performed in ECC-disabled mode, they will also affect
|
||||||
|
the ECC flash region. Erasing a 16k flash sector in the 0x00000000 area will
|
||||||
|
then also erase the corresponding 2k data bytes in the 0x48000000 area.
|
||||||
|
Writing to the ECC data bytes in ECC-disabled mode is not implemented.
|
||||||
|
@end quotation
|
||||||
|
|
||||||
|
Commands defined in the @var{psoc5lp} driver:
|
||||||
|
|
||||||
|
@deffn Command {psoc5lp mass_erase}
|
||||||
|
Erases all flash data and ECC/configuration bytes, all flash protection rows,
|
||||||
|
and all row latches in all flash arrays on the device.
