Refactor MCU status word and MCU firmware features reading to make it simpler to use. Signed-off-by: Marek Behún <kabel@kernel.org>
Implement reading board serial number, first MAC address and board version from MCU. MCU supports board information if the FEAT_BOARD_INFO feature bit is set in MCU features. Prefer getting board information from MCU if supported, fallback to Atmel SHA chip. Signed-off-by: Marek Behún <kabel@kernel.org>
If MCU supports the FEAT_CRYPTO feature, read board ECDSA public key from MCU and print it. Signed-off-by: Marek Behún <kabel@kernel.org>
If the FEAT_CRYPTO feature bit is present in MCU features, the board crypto is implemented by MCU and the Atmel SHA chip is not present. Disable Atmel SHA device-tree node in that case. Signed-off-by: Marek Behún <kabel@kernel.org>
Commit 35e29e8 ("arm: mvebu: Implement simple mvebu-reset driver for enabling/disabling PCIe ports") made it so that the mvebu reset driver for enabling/disabling PCIe ports is build if CONFIG_DM_RESET is enabled. This is because PCI_MVEBU depends on DM_RESET. But the driver should not be built for SPL. Indeed the PCI_MVEBU driver is not supported in SPL now, and so the mvebu-reset driver is not needed. Signed-off-by: Marek Behún <kabel@kernel.org>
The system-controller driver for 32-bit Armada is currently registered as UCLASS_RESET, since it only provides enabling/disabling PCIe ports. Rework it as UCLASS_SYSCON and bind mvebu-reset as a child device. Signed-off-by: Marek Behún <kabel@kernel.org>
…MVEBU The mvebu-reset driver is only needed by the mvebu PCIe driver, but currently it is automatically selected if DM_RESET is enabled. Add the condition of PCI_MVEBU also being enabled for mvebu-reset to be selected. Signed-off-by: Marek Behún <kabel@kernel.org>
Add driver model support for sysreset via mvebu system controller. This is currently only available for U-Boot proper. Signed-off-by: Marek Behún <kabel@kernel.org>
U-Boot builds for Turris Omnia are approaching the limit of 0xf0000 bytes, which is the size of the U-Boot partition on Omnia. Enable LTO to get more size optimized binaries. Signed-off-by: Marek Behún <kabel@kernel.org>
Since commit 8cd4bf7 ("turris: Use checkboard() instead of show_board_info()") the model is show two times during boot: Model: Turris Omnia Model: Turris Omnia This is because the common function show_board_info() shows it, and Turris' checkboard() also does. Remove the second print. Fixes: 8cd4bf7 ("turris: Use checkboard() instead of show_board_info()") Signed-off-by: Marek Behún <kabel@kernel.org>
Use byteorder conversion function instead of manually assembling data from/to MCU. Signed-off-by: Marek Behún <kabel@kernel.org>
Add header containing all MCU command definitions and use it in board code and in MCU driver. Signed-off-by: Marek Behún <kabel@kernel.org>
Add support for system power off via UCLASS_SYSRESET. Newer versions of Turris Omnia MCU firmware can power off the board (MCU will disable almost all voltage regulators and go into low power mode). Move the MCU driver into drivers/misc and register it under UCLASS_MISC. The sysreset and gpio device are bound as child devices of the MCU device. Signed-off-by: Marek Behún <kabel@kernel.org>
…config Enable support for the poweroff command via sysreset for Turris Omnia. Signed-off-by: Marek Behún <kabel@kernel.org>
In the rng command, print Abort instead of Reading RNG failed if the error number is -EINTR. Signed-off-by: Marek Behún <kabel@kernel.org>
Add support for true random number generator provided by the MCU on Turris Omnia. The MCU firmware supports TRNG if the FEAT_TRNG bit is set in features. In that case we bind the rng driver. Signed-off-by: Marek Behún <kabel@kernel.org>
Now that Turris Omnia has a rng driver provided in the MCU driver, enable the rng command in defconfig. Signed-off-by: Marek Behún <kabel@kernel.org>
