Hi Anatolij, Stefan,
The memory space is displayed in BAR2 of the PCI configuration space.
The video driver accesses this memory space and the exception is generated.
driver source: u-boot/drivers/video/ati_radeon_fb.c
function name: void *video_hw_init(void)
line : 760line
I attach the log where the exception is generated.
I confirmed it by the source of the following patches.
----- patch ------
#undef CONFIG_VIDEO
#ifdef CONFIG_VIDEO
#define CONFIG_BIOSEMU
#define CONFIG_ATI_RADEON_FB
#define VIDEO_IO_OFFSET 0xD8000000
#define CONFIG_SYS_ISA_IO_BASE_ADDRESS VIDEO_IO_OFFSET
#define CONFIG_VIDEO_SW_CURSOR
#define CONFIG_VIDEO_LOGO
#define CONFIG_CFB_CONSOLE
#define CONFIG_SPLASH_SCREEN
#define CONFIG_VGA_AS_SINGLE_DEVICE
#define CONFIG_CMD_BMP
#endif /* #ifdef CONFIG_VIDEO */
