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,
Renaud
