2023-05-21ddr: imx93: update the ddr init to support mult setpointsJacky Bai
Update the DDR init flow for multi-setpoint support on i.MX93. A new fsp_cfg struct need to be added in the timing file to store the diff part of the DDRC and DRAM MR register for each setpoint.

2022-07-26ddr: imx8m: helper: load ddr firmware according to binman symbolsPeng Fan
By reading binman symbols, we no need hard coded IMEM_LEN/DMEM_LEN after we update the binman dtsi to drop 0x8000/0x4000 length for the firmware. And that could save binary size for many KBs.

2022-07-26ddr: imx: Add i.MX9 DDR controller driverYe Li
Since i.MX9 uses same DDR PHY with i.MX8M, split the DDRPHY to a common directory under imx, then use dedicated ddr controller driver for each iMX9 and iMX8M. The DDRPHY registers are space compressed, so it needs conversion to access the DDRPHY address. Introduce a common PHY address remap function for both iMX8M and iMX9 for all PHY registers accessing.
