Hi Alice,

This is unfortunate - is the ROM API not going to be usable for the
imx95 or is support code simply not written yet? I don't really
understand the difference for example between the imx8mm BOOTROM and
the imx8mp/mn BOOTROMv2 where BOOTROMv2 can use the for SDP which
greatly reduces the SPL footprint.

Have you been able to configure U-Boot SPL for imx95 SDP? I am
overflowing .sram codespace when I try to add 'either' support for the
USB2.0 controller or the USB3.0 controller.

Best Regards,

Tim
