I'm struggling with the DRAM-size in U-Boot. Our custom board solution uses a 1Gb LPDDR4 RAM, so I changed the PHYS_SDRAM_SIZE in imx8mm_evk.h to 0x4000 0000, the DDR is configured with the stress tool. But in the bootlog it still says DRAM: 2GiB. With debug messages I traced...
We need to use remoteproc on i.MX93 with 512Mb of DDR4. On EVK with 2Gb , it's ok vith default address of rings buffer. If I change adress of rings buffer (in the first 512Mb) on EVK and my board, I have the followings errors. [ 46.127624] remoteproc remotep...

Rather than passing a hardcoded maxsize to the generic get_ram_size() function use the i.MX 7 specific imx_ddr_size() function, which extracts the memory size at runtime by reading the DDR controller registers. This is a purely cosmetic change as the generic get_ram_size() function alre...
Use imx_ddr_size() to retrieve the total DDR size instead of passing a hardcoded memory size. imx_ddr_size() calculates the memory size based on the actual MMDC registers values and is useful to detect misconfigurations, so switch to this more robust approach. Signed-off-by: Fabio Estevam...
