BSP

• Update to Yocto Kirkstone

U-Boot

• Update imx-seco
• Update imx seco-libs
• Update imx-sc-firmware

Linux

• Linux 5.15 support based on linux-fslc 5.15 + imx

U-Boot

• Support booting UBI rootfs from SPI NOR
• Use local version as implemented in branch zeus-tqma8. This will make the U-boot version string consistent with newer and upcomming kernel version string and consists of <upstream version>-tq+g<git short hash>
• Support for large micron SPI NOR on TQMa8Xx / TQMa8x flash was discovered but progam / erase silently fails. Backport upstream driver changes for FlexSPI IP and use this driver instead of the older one.
• TQMa8[all variants] adjust DEFAULT_FDT_FILE to kernel 5.10 used in this BSP. This is also the naming scheme that will be found in linux-mainline.

Linux

• Rewrite to use linux-yocto class
• Force build vivante gpu driver for linux-tq-imx as out of tree module to ensure versions between module and userland match. Overrides default assignments from meta-freescale.
• Switch to use linux-yocto for kernel fragment handling
• Remove support for i.MX8 based machines

• Update tqma8-cortexm-demos version: basic CortexM4 support for TQMa8Xx[S]
• Disable packages only relevant for NXP STK:
  • nxp8987 WiFi
  • imx-m[4,7]-demos
• Migrate all imx8 machines with U-Boot v2020.04 support to NXP BSP version
• Migrate all machines to NXP BSP version

U-Boot

• Add reserved memory nodes in DT to prevent U-Boot accessing M4 reserved memory
• Allow building bootstream with Cortex M4 demo for TQ Systems SOM
• Fix location U-Boot config node in DT
• Prevent voltage switch error message for e-MMC. This is not a real error but ugly behaviour which was fixed for other SOM before

• DSR support for Micron SPI NOR
• I2C recovery gpio

Linux

• Device trees for Cortex M4 demos
• Set CAN PDRV to low
• Upstream fixes from linux-imx

  • Remove unused net devices
  • Enable Vision Components GmbH MIPI CSI cameras
• DSR support for Micron SPI NOR
• I2C recovery gpio

BSP

• config/machines: sanitize variable assignments to improve reusability
  • Replace IMAGE_INSTALL_append with more approbiate MACHINE_EXTRA_RRECOMMENDS_append
  • Remove all dirty magic for DISTRO_FEATURES_remove
  • Replace hard assignments to IMAGE_BOOT_FILES with ?=

U-Boot

• v2020.04 fix FEC Ethernet PHY init
  • Fix phy_config using devicetree
  • Forward error from phy_config

BSP

• support for tqma8xdp[4]-mba8xx

U-Boot

• Fix board name for TQMa8XDP[4]

Linux

• Support for tqma8xdp[4]-mba8xx

U-Boot

• Fix not working update scripts when exchanging an SD card just before start updating
• Allow DSR for Macronix SPI NOR on all supported TQ-Systems SOM

Linux

• Backport improvements for TI TLV320AIC32x4 codec
• Lower drive strength for some pins
• QSPI NOR DSR
• Adjust thermal trip points
• Reenable audio in DT (deadlock fixed for I2C host)
• Fix deadlock i2c-imx-lpi2c
• Fix PMIC / CPU thermal sensor support
• Allow DSR for Macronix SPI NOR on all supported TQ-Systems SOM
• Add DSR support for Macronix flash
• Enable VPU support

BSP

• Update SCFW to tq-TQMa8.NXP-v1.6.0.B4894.0030
• Use Release Version of SC Firmware without debug output
• Update to U-Boot imx-5.4.47-2.2.0

• Fix missing dependency on bison-native for u-boot-fw-utils-imx-tq
• Rewrite systemd-machine-units bbappend to conform to new systemd version. CAN does not need separate units, but a simple network definition
• Add Support for TQMa8XQP4. The new machine needs a different bootstream hence a differen SCU firmware. The rest is equal to the existing TQMa8XQP.

U-Boot

• Support for TQMa8XQP4 as variant of TQMa8Xx (defconfigs, memory defines)
• Use same asound.state for all TQMa8 boards. Depends on linux support
• Fixed missing defines for default mtest addresses
• Use weak assignments for IMXBOOT_TARGETS to allow overrides and to prevent generating invalid bootstreams in imx-boot-mfgtool_
