HI ,
I am using DM8148 EVM. My PSP version is 04.04.00.02. I have followed the following link for vpss
http://processors.wiki.ti.com/index.php/TI81XX_PSP_VPSS_Video_Driver_User_Guide
After flashing the new kernel image and all the driver modules in the SD card, when I ran it I am getting the gollowing error. The full logs are attached
VPSS_FVID2: M3 firmware version 0x1000145 is newer,driver may not work properly.

BUG: Your driver calls ioremap() on system memory. This leads
to architecturally unpredictable behaviour on ARMv6+, and ioremap()
will fail in the next kernel release. Please fix your driver

FATAL: Error inserting vpss (/lib/modules/2.6.37/kernel/drivers/video/ti81xx/vpss/vpss.ko): No such device
BUG: Your driver calls ioremap() on system memory. This leads
to architecturally unpredictable behaviour on ARMv6+, and ioremap()
will fail in the next kernel release. Please fix your driver.
