85d0580e68 imx8ulp: clock: Fix lcd clock algo
The div loop uses reassign and reuse parent_rate, which causes
the parent rate reference to be wrong after the first loop, the
resulting clock becomes incorrect for div != 1.

Fixes: 829e06bf41 ("imx8ulp: clock: Add MIPI DSI clock and DCNano clock")

c916fb1747 imx: imx8ulp: Change LPAV assignment for dual boot
Assign the LPAV owner to RTD, and assign LPAV masters and peripherals
to APD. So except the masters and peripherals, other resources
(like DDR, cgc2, pcc5) in LPAV won't be reset during reboot and suspend.

No needs to initialize DDR again after reboot.

When reset with dual boot mode, the LPAV domain won't power down
due to its master is not assigned to APD. So the NICLPAV keeps the
last setting to use PLL4PFD1. So before SPL initialize the PLL4,

Current S400 has issue if the XRDC has released to A35, then A35 reset
will fail in ROM due to S400 fails to get XRDC.
So temp work around is checking the DBD_EN, if it is not fused, we

To enable the full l2 cache (512KB), it needs to reset A35 to make
the change happen.

So re-implement the jump entry function in SPL:
1. configure the core0 reset vector to entry (ATF)
2. enable the L2 full cache
3. reset A35
So when core0 up, it runs into ATF. And we have 512KB L2 cache working.
