From: Ashok Reddy Soma Date: Wed, 14 Jun 2023 12:13:50 +0000 (-0600) Subject: xilinx: versal-net: Add mini ospi configuration X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=38e0fc06b20d527e99ae18bb99c71c5e83b86864;p=u-boot.git xilinx: versal-net: Add mini ospi configuration Add support for Versal NET mini Octal SPI flash configuration. This runs from onchip memory, so it has to be compact. Hence only Octal SPI related settings are enabled.
