* sunxi: binman: Add support for including SCP firmwareSamuel Holland2020-10-221-0/+4
| | | | | | | | | | | | | | | | | Allwinner sun50i SoCs contain an OpenRISC 1000 CPU that functions as a System Control Processor, or SCP. ARM Trusted Firmware (ATF) communicates with the SCP over SCPI to implement the PSCI system suspend, shutdown and reset functionality. Currently, SCP firmware is optional; the system will boot and run without it, but system suspend will be unavailable. Since all communication with the SCP is mediated by ATF, the only thing U-Boot needs to do is load the firmware into SRAM. The SCP firmware occupies the last 16KiB of SRAM A2, immediately following ATF.
