Sure, I will test it and will let you know how it goes.

In the meantime, I am wondering if the change below would allow your
board to boot:

--- a/arch/arm/cpu/armv7/mx6/soc.c
+++ b/arch/arm/cpu/armv7/mx6/soc.c
@@ -105,6 +105,10 @@ void init_aips(void)
 #ifdef CONFIG_MX6SX
        struct aipstz_regs *aips3;
 #endif
+       struct mxc_ccm_reg *ccm = (struct mxc_ccm_reg *)CCM_BASE_ADDR;
+
+       /* Turn on AIPS1 and AIPS2 clocks */
+       setbits_le32(&ccm->CCGR0, 0xf);

        aips1 = (struct aipstz_regs *)AIPS1_BASE_ADDR;
        aips2 = (struct aipstz_regs *)AIPS2_BASE_ADDR;
