From 83ea9472389530b78d1a5daae267e7e75e4533dd Mon Sep 17 00:00:00 2001 From: Siva Durga Prasad Paladugu Date: Fri, 7 Feb 2025 11:19:51 +0530 Subject: [PATCH] firmware: xilinx: Dont send linux address to get fpga config get status [ Upstream commit 5abc174016052caff1bcf4cedb159bd388411e98 ] Fpga get config status just returns status through ret_payload and there is no need to allocate local buf and send its address through SMC args. Moreover, the address that is being passed till now is linux virtual address and is incorrect. Corresponding modification has been done in the firmware to avoid using the address sent by linux.
