From 81d0d89613c2eb30763c8cd04b36625b856eef38 Mon Sep 17 00:00:00 2001 From: Felix Held Date: Fri, 29 Apr 2022 18:38:55 +0200 Subject: soc/amd/common/block/psp/psp_gen2: rename cmd_response to buffer The cmd_response field in the pspv2_mbox struct is the buffer used to pass data to the PSP and back to the x86 side, so rename it to buffer. This also aligns the code a bit more with the reference code. Also rename the wr_mbox_cmd_resp function to wr_mbox_buffer_ptr.
