The uboot-fastboot developed by eureka it is more suited as start point, I'll try to remove the flash part and enable the part to load the kernel+initramfs.

There are a couple other things to consider -
To use Amazon's source (recommended), you will have to use "source dir override" so you can un-pack their u-boot source (2009-08 IIRC) into a local dir rather than let BR download the current.
I don't think eureka ever put his changes in a public repo -
Although he/she did post the diff files here.
I would:
Download the 5.6.1.1 source code tarball from Amazon it runs on both the PW1 (i.MX5) and the PW3 (i.MX6), perhaps not the same build, but the same source code release.
Init the directory tree made by the u-boot tarball as a local git repo.
Then checkout a branch -
Then apply eureka's diff -
Use git features to do the merge -
Then work with that (which, when your satisfied with it,) can be used as the target of a source dir override.
The advantages of working under source control + the advantages of using an automated build system for anything non-customized.
There is also some trick to declaring that BR should use the u-boot .config in the external directory.
The on-line user's manual is the key document.
