* ddr: imx: Handle both 3733 and 3732 MTps ratesMarek Vasut2023-01-301-0/+1
| | | | | | | | The DDR calibration tool for i.MX8M currently produces 3732 MTps rate in lpddr4_timing.c , while the PHY code expects 3733 MTps rate. Support both variants to avoid surprises where the system fails to boot. Signed-off-by: Marek Vasut <marex@denx.de>
* ddr: imx8m: helper: load ddr firmware according to binman symbolsPeng Fan2022-07-261-6/+41
| | | | | | | | | | | | | 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.

* ddr: imx: Add i.MX9 DDR controller driverYe Li2022-07-266-0/+1197
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.
