This patch adds support for Xilinx Kria KD240 starter kit. KD240 features can be found here: https://www.xilinx.com/products/som/kria/kd240-drives-starter-kit.html While the Kria SOM is based on a ZynqMP SoC, there are some key boot config differences from the other ZynqMP evaluation boards. 1. There are no boot switches on Kria SOMs. The boot mode is thus hard configured for QSPI flash. A pre-programmed boot.bin comes with every Starter Kit. U-Boot can then find the Linux kernel and file system on the SD card. Optional instructions for updating the boot.bin in the QSPI flash can be found in the readme.txt file and the link below. https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/1641152513/Kria+K26+SOM 2. Kria SOMs use UART1 for the console instead of UART0. For this reason, Kria Starter Kits will use a separate extlinux.conf file from other ZynqMP evaluation boards. 3. The KD240 has a USB to SD card bridge, so the Linux kernel and file system are found on /dev/sda1 and /dev/sda2. 4. The following patches have been submitted upstream to u-boot. Without these patches, the usb, sd card and ethernet peripherals do not work correctly. https://patchwork.ozlabs.org/project/uboot/patch/20231213134007.2818069-1-neal.frager@amd.com/ https://patchwork.ozlabs.org/project/uboot/patch/20231213134052.2818879-1-neal.frager@amd.com/ Signed-off-by: Neal Frager <neal.frager@amd.com> Reviewed-by: Luca Ceresoli <luca.ceresoli@bootlin.com> [Peter: add upstream tag, drop patch numbering from patches] Signed-off-by: Peter Korsgaard <peter@korsgaard.com>
