Hi Masahiro,
I am not able to boot Linux onF PowerPC platform with ramdisk size > 100MB. I tried u-boot master with top commit as " 5ac5861c4ba851b473e6a24940b412b397627d8d ".
I tried git-bisect and figured out below patch causing this problem. If I revert this patch, Linux boots properly.

image: check "bootm_low" and "bootm_size" if "initrd_high" is missing
To boot Linux, we should prevent Initramdisk and FDT from going too high.
Currently, boot_relocate_fdt() checks "fdt_high" environment first, and then falls back to getenv_bootm_mapsize() + getenv_bootm_low() if "fdt_high" is missing.
On the other hand, boot_ramdisk_high() only checks "initrd_high" to get the address limit for the Initramdisk. We also want to let this case fall back to getenv_bootm_mapsize() + getenv_bootm_low().
