[iMX51] Workaround in my BSP : Write in AIPS 0x77777777?

In my Bsp of iMX512, a work around is executed at the beginning:

 

/* workaround for UART SDMA support */

 

    LDR r1, =0x73F00000

    LDR r2, =0x77777777

    STR r2, [r1]

 

The 0x73F00000 address seems to be inside AIPS but this is not documented by Freescale.

Do you have any information about the purpose of this workaround? Is it the correct address?

 

Thank you in advance for your help.

Florent
