More Qualcomm driver updates for v6.7 The Qualcomm SMC an QSEECOM drivers are moved into a "qcom" subdirectory, to declutter the base directory. Missing include guards are added to the qseecom header file. Unneded extern specifiers are removed from the scm call wrappers. __counted_by is added to the apr_rx_buf structure, in the APR driver. Lastly in the pmic_glink driver the pmic_glink drm_bridge type is corrected to DisplayPort, over the incorrect "USB" value. The return values are added to error prints for the various typec set() calls. * tag 'qcom-drivers-for-6.7-2' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: soc: qcom: pmic_glink_altmode: Print return value on error firmware: qcom: scm: remove unneeded 'extern' specifiers firmware: qcom: scm: add a missing forward declaration for struct device firmware: qcom: move Qualcomm code into its own directory soc: qcom: apr: Add __counted_by for struct apr_rx_buf and use struct_size() soc: qcom: pmic_glink: fix connector type to be DisplayPort firmware: qcom: qseecom: add missing include guards Link: https://lore.kernel.org/r/20231025201109.1016121-1-andersson@kernel.org Signed-off-by: Arnd Bergmann

EDAC/versal: Add a Xilinx Versal memory controller driver

2023-10-23T17:41:27Z

Add a EDAC driver for the RAS capabilities on the Xilinx integrated DDR Memory Controllers (DDRMCs) which support both DDR4 and LPDDR4/4X memory interfaces. It has four programmable Network-on-Chip (NoC) interface ports and is designed to handle multiple streams of traffic. The driver reports correctable and uncorrectable errors, and also creates debugfs entries for testing through error injection. [ bp: - Add a pointer to the documentation about the register unlock code. - Squash in a fix for a Smatch static checker issue as reported by Dan Carpenter: https://lore.kernel.org/r/a4db6f93-8e5f-4d55-a7b8-b5a987d48a58@moroto.mountain ] Co-developed-by: Sai Krishna Potthuri Signed-off-by: Sai Krishna Potthuri Signed-off-by: Shubhrajyoti Datta Signed-off-by: Borislav Petkov (AMD) Link: https://lore.kernel.org/r/20231005101242.14621-3-shubhrajyoti.datta@amd.com

Qualcomm driver updates for v6.7 This introduces partial support for the Qualcomm Secure Execution Environment SCM interface, and uses this to implement EFI variable access on the Windows On Snapdragon devices (for now). The 32/64-bit calling convention detector of the SCM interface is updated to not choose 64-bit convention when Linux is 32-bit. The "extern" specifier is dropped from the interface include file. The LLCC driver gains support for carrying configuration for multiple different system/DDR configurations for a given platform, and selecting between them. Support for Q[DR]U1000 is added to the driver. All exported symbols are transitioned to EXPORT_SYMBOL_GPL(). The platform_drivers in the Qualcomm SoC are transitioned to the void-returning remove_new implementation. The rmtfs memory driver gains support for leaving guard pages around the used area, to avoid issues if the allocation happens to be placed adjacent to another protected memory region. The socinfo driver gains knowledge about IPQ8174, QCM6490, SM7150P and various PMICs used together with SM8550. * tag 'qcom-drivers-for-6.7' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: (44 commits) soc: qcom: socinfo: Convert to platform remove callback returning void soc: qcom: smsm: Convert to platform remove callback returning void soc: qcom: smp2p: Convert to platform remove callback returning void soc: qcom: smem: Convert to platform remove callback returning void soc: qcom: rmtfs_mem: Convert to platform remove callback returning void soc: qcom: qcom_stats: Convert to platform remove callback returning void soc: qcom: qcom_gsbi: Convert to platform remove callback returning void soc: qcom: qcom_aoss: Convert to platform remove callback returning void soc: qcom: pmic_glink: Convert to platform remove callback returning void soc: qcom: ocmem: Convert to platform remove callback returning void soc: qcom: llcc-qcom: Convert to platform remove callback returning void soc: qcom: icc-bwmon: Convert to platform remove callback returning void firmware: qcom_scm: use 64-bit calling convention only when client is 64-bit soc: qcom: llcc: Handle a second device without data corruption soc: qcom: Switch to EXPORT_SYMBOL_GPL() soc: qcom: smem: Annotate struct qcom_smem with __counted_by soc: qcom: rmtfs: Support discarding guard pages dt-bindings: reserved-memory: rmtfs: Allow guard pages dt-bindings: firmware: qcom,scm: document IPQ5018 compatible firmware: qcom_scm: disable SDI if required ...

firmware: qcom_scm: Add support for Qualcomm Secure Execution Environment SCM interface

2023-09-13T17:18:42Z

Add support for SCM calls to Secure OS and the Secure Execution Environment (SEE) residing in the TrustZone (TZ) via the QSEECOM interface. This allows communication with Secure/TZ applications, for example 'uefisecapp' managing access to UEFI variables. For better separation, make qcom_scm spin up a dedicated child (platform) device in case QSEECOM support has been detected. The corresponding driver for this device is then responsible for managing any QSEECOM clients. Specifically, this driver attempts to automatically detect known and supported applications, creating a client (auxiliary) device for each one. The respective client/auxiliary driver is then responsible for managing and communicating with the application. While this patch introduces only a very basic interface without the more advanced features (such as re-entrant and blocking SCM calls and listeners/callbacks), this is enough to talk to the aforementioned 'uefisecapp'.

drivers: meson: sm: correct meson_sm_* API retval handling

2023-09-11T09:45:26Z

1. Following the ARM SMC32 calling convention, the return value from secure monitor is a 32-bit signed integer. This patch changes the type of the return value of the function meson_sm_call(). 2. Now, when meson_sm_call() returns a 32-bit signed integer, we need to ensure that this value is not negative. It is important to check that the return value is not negative in both the meson_sm_call_read() and meson_sm_call_write() functions. 3. Add a comment explaining why it is necessary to check if the SMC return value is equal to 0 in the function meson_sm_call_read(). It is not obvious when reading this code.
