powerpc/mpc85xx: T104x: Add nand secure boot target For mpc85xx SoCs, the core begins execution from address 0xFFFFFFFC. In non-secure boot scenario from NAND, this address will map to CPC configured as SRAM. But in case of secure boot, this default address always maps to IBR (Internal Boot ROM). The IBR code requires that the bootloader(U-boot) must lie in 0 to 3.5G address space i.e. 0x0 - 0xDFFFFFFF. For secure boot target from NAND, the text base for SPL is kept same as non-secure boot target i.e. 0xFFFx_xxxx but the SPL U-boot binary will be copied to CPC configured as SRAM with address in 0-3.5G(0xBFFC_0000) As a the virtual and physical address of CPC would be different. The virtual address 0xFFFx_xxxx needs to be mapped to physical address 0xBFFx_xxxx. Create a new PBI file to configure CPC as SRAM with address 0xBFFC0000 and update DCFG SCRTACH1 register with location of Header required for secure boot. The changes are similar to commit 467a40dfe35f48d830f01a72617207d03ca85b4d powerpc/mpc85xx: SECURE BOOT- NAND secure boot target for P3041 While P3041 has a 1MB CPC and does not require SPL. On T104x, CPC is only 256K and thus SPL framework is used. The changes are only applicable for SPL U-Boot running out of CPC SRAM and not the next level U-Boot loaded on DDR.
