Subject: drm/amdgpu: check kdb_bin_size to exclude kdb loading sequence
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=f216994613bc9f44202eac3a298e52124eb3e35e;p=openwrt%2Fstaging%2Fblogic.git

drm/amdgpu: check kdb_bin_size to exclude kdb loading sequence

The legacy navi10 sos binary will not carry on kdb image. the kdb_start_addr
is actually the start address of sys_drv image and shouldn't be sent to psp
bootloader.
