I can remove the flash_ prefix, this generic FS loader should support for all filesystem instead of flash.
I also mentioned the API should copy the linux firmware loader API.
If i'm not mistaken, you are referring firmware loader API in this link https://github.com/torvalds/linux/blob/f007cad159e99fa2acd 3b2e 9364 fbb32ad28b971/drivers/base/firmware_class.c#L1264.
I would like to confirm with you whether we are talking to the same API above?
https://www.kernel.org/doc/html/v4.13/driver-api/firmware/index.html
first link on google btw . You might be able to avoid the firmware structure.
After assessment, i found that Linux loader is not suitable for fpga loader as fpga loader need
- Able to program FPGA image in SPL chunk bu chunk with small memory
allocatted. 2) Name of FPGA image defined in DTS, and path of FPGA image in FAT and UBI partition.
Linux loader is strongly designed based on Linux environment, always assume having RFF, env support(which SPL don't have), sysfs and udev feature.
Sigh, you can just have some additional function call to fetch smaller chunks from a file, I don't think it's that hard of a problem ...
