That is very different than the kernel parameters you're passing when
using grub: root=/dev/ram0 iso-scan/filename=${isofile} console=tty1
console=ttyS1,115200n8 ramdisk_size=102400
It also appears as though you're loop booting from an iso image when
booting via grub, but not doing so when booting via uboot (no
iso-scan/filename= parameter when booted via uboot), which would be a
significant difference as well.
Try loading exactly the same kernel and initramfs, with exactly the
same kernel parameters ( console=ttyS1,115200 console=tty1
root=/dev/ram ramdisk_size=102400 ) using grub and I expect it will
boot the same way it does with uboot.
