With this patch applied following warnings appear:
ati_radeon_fb.c: In function 'video_hw_init':
ati_radeon_fb.c:740: warning: assignment makes integer from pointer without a
cast
ati_radeon_fb.c:741: warning: assignment makes integer from pointer without a
cast
ati_radeon_fb.c:746: warning: assignment makes integer from pointer without a
cast
ati_radeon_fb.c:754: warning: assignment makes integer from pointer without a
cast
ati_radeon_fb.c:755: warning: assignment makes integer from pointer without a
cast
Please include inlined patch below to fix them. Thanks.
Other than this, I tested this patch on PPC440EPx based sequoia board
with ATI Radeon 9250 PCI card, it works.
