2023-06-16board: stm32mp1: use fdt_copy_fixed_partitionsPatrick Delaunay
Copy the fixed partition nodes from U-Boot device tree to Linux kernel device tree to dynamically configure the MTD partitions. fdt_copy_fixed_partitions is only based on device tree and replace the function fdt_fixup_mtdparts based on mtdparts variable; the variable mtdid and mtdparts are not more required.

2023-06-16arm: dts: stm32: Add partitions in flash0 and nand node for stm32mp15xx-ev1Patrice Chotard
Add partitions subnode in flash0 and nand nodes for all stm32mp157xx-ev1 boards. Update only the file stm32mp157c-ev1-*u-boot.dtsi, included by other files stm32mp15*-ev1-*-u-boot.dtsi. For SCMI variant of device tree used with stm32mp15_defconfig add partitions needed by TF-A firmware update: - metadata to save the TF-A information: 2 copy - fip-a / fip-b: two FIP slots, used for system A/B (seamless) update - the previous "fsbl" partition with 2 copy of TFA is replaced by 2 partitions (only one copy in each MTD partition) to simplify the update: no need to managed this copy on update, need to update the two partition (skip bad block for NAND) The offset for ENV partition are also updated in stm32mp15_defconfig Signed-off-by: Patrick Delaunay <patrick.delaunay@foss.st.com> Signed-off-by: Patrice Chotard <patrice.chotard@foss.st.com> Reviewed-by: Patrice Chotard <patrice.chotard@foss.st.com>

2023-06-16stm32mp: stm32prog: Remove usage of "mtdparts" functionPatrice Chotard
Motivation for this patch is to remove usage of function define in cmd/mtdparts.c interface, based on env variables mtdids and mtdparts: mtdparts_init() and find_dev_and_part(). See commit 938db6fe5da3 ("cmd: mtdparts: describe as legacy") Now, all MTD devices are populated with their partition's information found in DT, accessible in MTD devices. Use these information to find the wanted partitions, no more need of find_dev_and_part() usage.

For a bit more context, the DPAA2 u-boot software architecture uses a default network interface object - a DPNI - which, at runtime, will get connected to the currently used DPMAC object.

2023-06-13test/py: Account PCR updates properly during testingIlias Apalodimas
Currently we only read the pcr updates once on test_tpm2_pcr_read(). It turns out that the tpm init sequence of force_init() which consists of: - tpm2 init - tpm2 startup TPM2_SU_CLEAR - tpm2 self_test full - tpm2 clear TPM2_RH_LOCKOUT also counts as an update. Running this in the console verifies the update bump => tpm2 init => tpm2 startup TPM2_SU_CLEAR => tpm2 self_test full => tpm pcr_read 10 $loadaddr PCR #10 content (28 known updates): 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 => tpm2 clear TPM2_RH_LOCKOUT => tpm pcr_read 10 $loadaddr PCR #10 content (29 known updates): 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 => With the recent changes of replacing 'tpm2 init' with 'tpm2 autostart' we end up always running the full init. The reason is 'tpm init' returns -EBUSY if the tpm is already open, while 'tpm autostart' handles ths gracefully and continues with the initialization. It's worth noting that this won't affect the device functionality at all since retriggering the startup sequence and selftests has no side effects. Instead of relying on the initial value, reread the 'known updates' just before updating the PCR to ensure we read the correct values before testing Reviewed-by: Simon Glass <sjg@chromium.org> Signed-off-by: Ilias Apalodimas <ilias.apalodimas@linaro.org>

2023-06-13tpm: Add 'tpm autostart' shell commandIlias Apalodimas
For a TPM device to be operational we need to initialize it and perform its startup sequence. The 'tpm init' command currently calls tpm_init() which ends up calling the ->open() per-device callback and performs the initial hardware configuration as well as requesting locality 0 for the caller. There no code that currently calls tpm_init() without following up with a tpm_startup() and tpm_self_test_full() or tpm_continue_self_test(). So let's add a 'tpm autostart' command and call tpm_auto_start() which leaves the device in an operational state. It's worth noting that calling tpm_init() only, doesn't allow a someone to use the TPM since the startup sequence is mandatory. We always repeat the pattern of calling - tpm_init() - tpm_startup() - tpm_self_test_full() or tpm_continue_self_test() Reviewed-by: Simon Glass <sjg@chromium.org> Signed-off-by: Ilias Apalodimas <ilias.apalodimas@linaro.org>

2023-06-12video: zynqmp: Driver for Xilinx ZynqMP DisplayPort SubsystemVenkatesh Yadav Abbarapu
The Xilinx ZynqMP SoC has a hardened display pipeline named DisplayPort Subsystem. It includes a buffer manager, blender, an audio mixer and a DisplayPort source controller (transmitter). The DisplayPort controller can source data from memory (non-live input) or the stream (live input). The DisplayPort controller is responsible for managing the link and physical layer functionality. The controller packs audio/video data into transfer units and sends them over the main link. The link rate and lane counts can be selected based on the application bandwidth requirements. The DisplayPort pipeline consists of the DisplayPort direct memory access (DMA) for fetching data from memory. The DisplayPort DMA controller (DPDMA) supports up to six input channels as non-live input. This driver supports the DisplayPort Subsystem and implements 1)640x480 resolution 2)RGBA8888 32bpp format 3)DPDMA channel 3 for Graphics 4)Non-live input 5)Fixed 5.4G link rate 6)Tested on ZCU102 board There will be additional work to configure GT lines based on DT, higher resolutions, support for more compressed video formats, spliting code to more files, add support for EDID, audio support, using clock framework for all clocks and in general code clean up.
