For this node you should just be able to do something like:
imx-boot {
filename = "imx-boot-imx95.bin";
pad-byte = <0x00>;
spl {
type = "mkimage";
args = "-n spl/u-boot-spl.cfgout -T imx8image";
align = <0x400>;
align-size = <0x400>;
};
You don't need to create intermediate files for all this stuff, so
drop your 'filename' properties.

similar for this one

Could this be moved to use standard boot?

How about putting this code in a separate function (called from
board_init_f()) so you can check errors consistently, and always hang
or panic in that situation?

Blobs should be accessed via environment variables (like TEE, BL31) or
using the binman input path. How about creating an IMX_BLOBS variable
and adding to Makefile like '-a imx-blobs=$(IMX_BLOBS)' - see
ti-dm-path for an example.
