| | | | | | | | | | | | | | | | | | | | | | | | | When running a NXP 4.1 kernel with U-Boot mainline on a mx6ul-evk, we observe a hang when going into the lowest operational point of cpufreq. This hang issue does not happen on the NXP U-Boot version. After comparing the SPL DDR initialization against the DCD table from NXP U-Boot, the key difference that causes the hang is the MDREF register setting: DATA 4 0x021B0020 0x00000800 ,which means: REF_SEL = 0 --> Periodic refresh cycle: 64kHz REFR = 1 ---> Refresh Rate - 2 refreshes So adjust the MDREF initialization for mx6ul_evk accordingly to fix the kernel hang issue at low bus frequency.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix 74LV OE gpio index. gpio index is wrong, so gpio output will not have effect, since we use wrong GPIO5_IO18, but not correct GPIO5_IO8. And at the end of the initialization of 74lv init, should keep OE voltage level at LOW to make 74lv output the correct voltage.
