This commit adds i.MX91 and i.MX93 support to Buildroot. https://www.nxp.com/products/processors-and-microcontrollers/arm-processors/i-mx-applications-processors/i-mx-9-processors:IMX9-PROCESSORS There is no i.MX95 software provided by NXP at the moment that's why i.MX95 is left behind. Adapt package firmware-imx for the LPPDR4 firmware binaries. The i.MX91 and i.MX93 only support LPDDR4 and LPDDR4x, but using different binaries than i.MX8. For simplicity, use a completely separate code path for i.MX91 and i.MX93, using the symbol BR2_PACKAGE_FIRMWARE_IMX_NEEDS_DDR_FW_IMX9. There is only one type of firmware supported, so there's no need for a choice or for selecting the version (at least for now).

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC.
