The DRAM PHY layer on PH1-LD20 is able to calibrate PHY parameters periodically. This compensates for the voltage and temperature deviation and improves the PHY parameter adjustment. Instead, it requires 64 byte scratch memory in each DRAM channel for the dynamic training. The memory regions must be reserved in DT before jumping to the kernel. The scratch area can be anywhere in each DRAM channel, but the DRAM init code in SPL currently assigns it at the end of each channel. So, it makes sense to reserve the regions on run-time by U-Boot instead of statically embedding it in the DT in Linux. Anyway, a boot-loader should know much more about memory initialization than the kernel. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
