The default addresses to load the kernel, fdt, initrd of AMCC boards
in U-Boot v2015.10 are :
"kernel_addr_r=1000000\0"
"fdt_addr_r=1800000\0"
"ramdisk_addr_r=1900000\0"
The taihu is one of these boards, the ref405ep is not but we don't
have much information on it and both boards have a very similar
address space layout. Change the kernel load address to match U-Boot
expectations and fix loading.
You could additionally mention that U-Boot corrupts the kernel if it gets
loaded to address 0.
True. The first word is overwritten with zeros. I looked for it
in the code but could not find the reason.
Thanks,
C.
