Series implements some of the new NVMEM bindings:
- New providers:
- nvmem-cells (for MTD partitions)
- nvmem-rmem (memory regions passed by previous boot stages)
- New consumers:
- Network devices: Unlike Linux, we do that for all drivers
in generic code. This is done postenvironment, so network drivers,
board code and other (OTP) drivers are not overridden.
- nvmem-reboot-mode: To go along with syscon-reboot-mode
- nvmem command: This one only prints registered devices for now
And changes sandbox to make use of it.
Ahmad Fatoum (13):
nvmem: bsec: remove unused, left-over, struct member
nvmem: treat devices without nvmem_bus::write as read only
nvmem: add support for new read-only memory (rmem) binding
nvmem: add support for nvmem-cells binding
sandbox: use nvmem on top of stickypage for reset reason
power: reset: port Linux generic NVMEM reboot mode driver
sandbox: use nvmem-reboot-mode instead of syscon-reboot-mode
sandbox: dts: fix unit-address for state partition
nvmem: add command to list nvmem devices
sandbox: hostfile: move initcall to earlier postcore level
of: of_net: sync of_get_mac_address with Linux for NVMEM support
net: consult device tree for ethernet address in NVMEM as fall-back
sandbox: ship sample environment
