Add support for Xilinx versal2 devices which include two new applications for the xilinx-embeddedsw package. BR2_TARGET_XILINX_EMBEDDEDSW_VERSAL2_PLM There is a new PLM (platform loader and manager) application for versal2 devices. The purpose of the PLM is to act as the bootloader for loading the boot.pdi to configure the DDR memory and then loading arm-trusted-firmware and u-boot on the Cortex-A78 core 0. BR2_TARGET_XILINX_EMBEDDEDSW_VERSAL2_ASUFW Included with versal2 devices is a risc-v based security accelerator called the ASU (application security unit). The ASUFW is the open-source application which runs on the ASU. Versal2 devices simplified the boot process by getting rid of the second microblaze core called the PSM (processor system manager). There is thus no longer a need for a separate psmfw application like with the original versal devices, as this functionality is now fully included in the new PLM for versal2.

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. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
