imx: fix header inclusion guards

2023-05-31T14:11:46+00:00

It seems like the header inclusion guards for some IMX related headers
were misspelled or got out of sync.

Make the preprocessor symbols for the #ifndef and #define lines the
same, so that the double inclusion protection works as expected.

imx: ahab: Move imx9 and imx8ulp AHAB support together

2023-03-29T20:27:38+00:00

Use common file ele_ahab.c for i.MX9 and iMX8ULP AHAB support, since
both of them use same sentinel ELE APIs

imx: imx8ulp: Configure XRDC PDAC and MSC for DBD owner=S400 only

2023-03-29T18:15:42+00:00

This patch is used to support DBD owner fuse changed to S400 only.
The XRDC PDAC2 for LPAV pbridge5 and MSC1/2/3 for GPIO and LPAV are not
configured by S400 default setting.  So these PDAC and MSC are invalid,
only DBD owner can access the corresponding resources.

We have to configure necessary PDAC and MSC for SPL before DDR
initialization.

imx: imx8ulp: Adjust handshake to sync TRDC and XRDC completion

2023-03-29T18:15:42+00:00

To fit the DBD_EN fused part, we re-design the TRDC and XRDC assignment.
M33 will be the TRDC owner and needs to configure TRDC. A35 is the
XRDC owner, ATF will configure XRDC.

The handshake between U-boot and M33 image is used to sync TRDC and
XRDC configuration completion. Once the handshake is done, A35 and M33
can access the allowed resources in others domain.

The handshake is needed when M33 is booted or DBD_EN fused, because both
cases will enable the TRDC. If handshake is timeout, the boot will hang.
We use SIM GPR0 to pass the info from SPL to u-boot, because before the
handshake, u-boot can't access SEC SIM and FSB.
