TQ Group produces a system-on-module family called TQMa8Xx. The user manual for this SoM is available here: https://www.tq-group.com/filedownloads/files/products/embedded/manuals/arm/embedded-modul/TQ-Socket/TQMa8Xx/TQMa8Xx.UM.0104.pdf This SoM comes in a number of different configurations. The specific NXP SoC used, and the amount of memory are both configurable. The TQMa8XQP is the part number for the TQMa8Xx family configured with the i.MX 8QuadXPlus SoC. The datasheet for the SoC is available here: https://www.nxp.com/docs/en/data-sheet/IMX8QXPAEC.pdf In addition to the SoC being configurable the amount of SDRAM on the SoM is also configurable. The support provided in this PR is specifically for the TQMa8XQP configured for 1GiB of memory. Note: Actual usable memory available to the ARM application processor is 1022MiB. System-on-modules rely on an appropriate carrier board. Testing of this PR has been done on the MBa8Xx carrier board that is available from TQ Group as part of their starter kit. To the best of my knowledge there is nothing in this PR that depends on the carrier board itself; all code is SoM specific and should support any carrier board. Note: This support is very specifically for the TQMa8XQP configured with 1GiB of memory. This may be a starting point for supporting other boards that also have the NXP i.MX 8QuadXPlus SoC (as well as the i.MX 8DXP and possibly other SoC in the i.MX 8 family). Support is limited to the specific SoM due to the way in which platform support currently works for seL4. Building a kernel currently relies on the information from the DTS file (which is SoM + RAM configuration specific). It would be preferable to allow more generic support but SoC families but that is beyond the scope of this PR. Signed-off-by: Ben Leslie <benno@brkawy.com> |
