ls1046ardb tfa

[Renaud Barbier <Renaud.Barbier@ametek.com>]

We have a board using the LS1046A (based on the LS1046ARDB) and recently moved to v2025.06.1.
There is a failure to boot.
I noticed that the PPA support is gone from the ls1046ardb and enabled FIRMWARE_LS1046A_ATF and
built the bl31.bin file from  https://github.com/nxp-qoriq/atf.git which is copied under the directory firmware/
At present, I have a limited knowledge of TFA support.

The dram structure passed to bl31 is as follows:
 static struct dram_regions_info dram_info = {
           .num_dram_regions = 1,
           .total_dram_size = SZ_2G,
           .region = {
                   {
                           .addr = SZ_2G,
                           .size = SZ_2G,
                   },
           },
  };

Debug output:
Data Bus test:
        Walking 0: PASS
        Walking 1: PASS

Pattern Test:
        Pattern (ffffffff): PASS.............

Seeing the TQMLS1046A uses the BL31 firmware, I was wondering if my build of bl31.bin is correct.
Any help welcome.

Cheers,
