As the A64 is designed for use in mobile devices without easy access to
a UART, MMC0, or a FEL button, it would be useful to be able to reboot
to FEL mode, fastboot, etc. via a command from Linux. As reboot(2)
supports passing a command with LINUX_REBOOT_CMD_RESTART2, and we have
battery-backed
Store a reboot mode in one of the RTC's general purpose registers.
This value can be used by U-Boot or another bootlader, for example to
enter FEL or fastboot mode.

The sun6i RTC provides 64 bytes of general-purpose data registers.
They can be used to save data in the always-on RTC power domain.
The registers are writable via 32-bit MMIO accesses only.
Expose the region as a NVMEM provider so it can be used by userspace and
other drivers.

The #ifdef CONFIG_xxxPWR conditionals were not working as expected, as
string Kconfig symbols are always "defined" from the preprocessor's
perspective. This lead to unnecessary calls to the GPIO routines, but
also always added a half a second delay to wait for a SATA disk to power
up. Many thanks
