Added

• Machines:

  • MBa93xx[CA,LA] preparation for using with Quectel GSM/LTE modem
  • Support for TQMa93xxCA on MBa93xxCA was added. This SOM shares U-Boot and devicetree with TQMa93xxLA on adaptor. Machine tqma93xxla-mba93xxca was therefore renamed to tqma93xx-mba93xxca
  • Support for TQMa93xxLA on MBa93xxLA was added. The machine config files for TQMa93xxLA on MBa93xxCA were restructured to allow sharing settings for the boards. This prevents copy and paste and allows quickly adding new boards.
• linux-imx-tq 5.15 / imx on arm64:

  • enable support of GSM/LTE modules connected via USB. Tested with Quectel EC21.
  • enable RFKILL support in kernel config
• TQMLS1046A: add machine config for RAM without ECC
• TQMLS1046A: add u-boot-tq-2018.07 configs for Modules without ECC
• TQMa93xxLA: add wifi and bluetooth to MACHINE_FEATURES and enable firmware for WLAN cards with 88W8997 chipset
• TQMa8X[xS]: Known issue regarding hardware controlled chip-select
• TQMT10xx: add initial support for TQMT10xx based machines:

  • tqmt1040-64bit-stkt104x
  • tqmt1042-64bit-stkt104x
  • tqmt1022-64bit-stkt104x
  • tqmt1024-64bit-stkt104x

Fixed

• TQMa64xxL: enable SDHC controller quirk to fix SD card access on TQMa64xxL REV.010x SoMs.
• all machines: Fix a race condition due to missing dependencies for WKS_FILE_DEPENDS. Add EXTRA_IMAGEDEPENDS to WKS_FILE_DEPENDS for all machines.
• TQMa8MPxL: fix disabling of devices when no VARD can be used. Rather than dis- abling all optional devices, print a warning and try to boot. Without the warning this restores the behaviour before handling optional devices with VARD.
• machines: fix display related features in MACHINE_FEATURES Use screen and touchscreen since this is what Yocto Project / OpenEmbedded use. Remove display which was in use solely in TQ-Systems layers.
• machines: clean WKS_FILE_DEPENDS and make sure it contains e2fsprogs-native. This prevents ext4 build errors during wix image creation. This kind of error occurs repeatedly when ext4 is not part of IMAGE_FSTYPES Additionally move all non host tools dependencies from WKS_FILE_DEPENDS to EXTRA_IMAGEDEPENDS
• MBa8Xx[S]: linux-imx-tq 5.15:

  • Pull-up configured for SPI chip-selects in kernel devicetree
  • use gpio chip select for SPI where possible to prevent toggling chip select due to SPI IP and DMA limitation
• linux-firmware: fix for multilib configurations

Removed

• Adjust and mostly remove recipes ported from meta-imx for i.MX93 support. These are ported to meta-freescale as of commit 642cf7f2 ("Merge pull request #1433 from Freescale/backport-1432-to-kirkstone")
• fm-ucode recipe removed and append for meta-freescale recipe added instead.

Changed

• TQMLS102xA

  • improve settings for U-Boot specific variables
  • allow easier usage with different RCW
  • u-boot-tq_2017.11: simplify recipe for TQMLS102xA
• imx-sc-firmware-tq_1.13.0 (TQMa8X[D,Q]P[S], TQMa8QM)

  • update to TQMa8.NXP-v1.13.0.B5561.0035
  • Improve DRAM memory region protection: only existing DRAM is partitioned
  • Move recipe out of dynamic-layers/freescale-layer. Since we provide our own binary package without dependencies to other layers the recipe does not need to be hidden.
• linux-tq 6.1 / TQMa8M: update to 6.1.9
• linux-imx-tq 5.15 / TQMa93xxLA:

  • cleanup gpio for LVDS on MBa93xxCA, make USB touch working
  • rename DT and compatible for MBa93xxCA
• u-boot-imx-tq 2022.04 / TQMa93xxLA

  • rename board and config names for MBa93xxCA
  • rename DT for MBa93xxCA
• tqma57xx: update machine configuration and bbappends for compatibility with latest meta-ti kirkstone (as of commit 38941472e1e3 "meta-ti-bsp: add BeagleBone AI-64 support")
• machines: improve usage of bitbake variables to express image dependencies Move packages from IMAGE_INSTALL:append to MACHINE_EXTRA_RRECOMMEND in machine config files.
• all imx based SOM: port changes from meta-imx kirkstone-5.15.71-2.2.0 in libdrm, weston, wayland-protocols as bbappend-files under dynamic layers to get the latest changes needed for imx93
• TQMa93xxLA: port and configure more graphic support from meta-imx
• TQMa93xxLA: rename starter kit mainboard to MBa93xxCA, therefore machine name is now tqma93xxla-mba93xxca
• u-boot-imx-tq 2022.04 / TQMa93xxLA

  • improve VARD support, fixup devictree
  • improve QSPI NOR support
  • speed grade / temperature grade handling
• linux-imx-tq 5.15:

  • TQMa93xxLA: LVDS support, QSPI support, USB at mPCIe slot,
  • enable enable marvel / nxp wifi driver in wifi support fragment
  • enable PWM driver needed for i.MX93
• TQMa93xxLA: update firmware-imx-9 to 8.18. Needs at least meta-freescale commit 8bd13d69 ("firmware-imx: Upgrade 8.17 -> 8.18")

BSP

• Update to Yocto Kirkstone 4.0.6
• Allow kernel image to be installed in rootfs per default
• Rewrite logic for KERNEL_DEVICETREE and device trees in IMAGE_BOOT_FILES. This removes the intermidiate variable BOARD_DEVICETREE_FILES
