2019-10-03firmware: meson_sm: Rework driver as a proper platform driverCarlo Caione1-6/+9
The secure monitor driver is currently a frankenstein driver which is registered as a platform driver but its functionality goes through a global struct accessed by the consumer drivers using exported helper functions. Try to tidy up the driver moving the firmware struct into the driver data and make the consumer drivers referencing the secure-monitor using a new property in the DT. Currently only the nvmem driver is using this API so we can fix it in the same commit.

2018-09-12firmware: meson_sm: Add serial number sysfs entryNeil Armstrong1-0/+1
The Amlogic Meson SoC Secure Monitor implements a call to retrieve an unique SoC ID starting from the GX Family and all new families. The serial number is simply exposed as a sysfs entry under the firmware sysfs directory. Signed-off-by: Neil Armstrong <[email protected]> Signed-off-by: Kevin Hilman <[email protected]>
2017-03-23firmware: meson-sm: Check for buffer output sizeCarlo Caione1-2/+2
After the data is read by the secure monitor driver it is being copied in the output buffer checking only the size of the bounce buffer but not the size of the output buffer. Fix this in the secure monitor driver slightly changing the API. Fix also the efuse driver that it is the only driver using this API to not break bisectability.

2016-09-01firmware: Amlogic: Add secure monitor driverCarlo Caione1-0/+31
Introduce a driver to provide calls into secure monitor mode. In the Amlogic SoCs these calls are used for multiple reasons: access to NVMEM, set USB boot, enable JTAG, etc...
