Not directly. I've been toying with a few ideas but not put any into practice yet. The first and possibly simplist would be to mimic the USB RNDIS in SPL support am335x uses (see am335x_evm_usbspl_defconfig) but I don't know if we have space for that. The second would be trying to "fake" things such that for imx_usb_loader you can pass both SPL and u-boot.img, and SPL is run, inits memory and just exists and then u-boot.img is loaded and run, similar to how with the non-SPL case you can use the loader to pass in u-boot.imx as well as a kernel, ramdisk, etc, into DDR. Proof of concepts, patches or just plain old feedback greatly appreciated! -- Tom
