Secure DRAM

System Software version 0.931.010 Secure DRAM

On System Software version 0.931.010, SKBL is stored at physical address 0x50000000. So, on System Software version 0.931.010, which data are stored at 0x40040000? Is it even considered as Secure DRAM?

ARZL compressed NSKBL is kept in place inside SKBL segment 0 (at offset 0x37100) til ARZL decoding to Non-secure DRAM at physical address 0x51000000.

FWs 0.990-0.995 Secure DRAM

On FWs 0.990-0.995, SKBL segment 0 starts at physical address 0x40040000.

ARZL compressed NSKBL is extracted from a kernel_boot_loader segment to Non-secure DRAM at physical address 0x50000000. It is then ARZL decoded to Non-secure DRAM at physical address 0x51000000.

FWs >=0.996 Secure DRAM

Since FW 0.996, SKBL segment 0 starts at physical address 0x40020000. This change could have come from the increasing SKBL segment 0 size with revisions.
