When booting on a 64-bit system, the boot_addr_start buffer is not
large enough to contain a 64-bit number, thus leading to a crash
even if fastboot_buf_addr is valid, only the high part of the address
will be printed to boot_addr_start :
fastboot with fastboot_buf_addr = 0x0000000006000000:
downloading of 92239872 bytes finished
Booting kernel at 0x00000000...
"Synchronous Abort" handler, esr 0x96000004
elr: 00000000010561f4 lr : 0000000001056fac (reloc)
<snip>
x28: 000000007df2d38f x29: 000000007df2d1b0
Resetting CPU ...
With this fix, boot_addr_start can have the full 64-bit address passed
to bootm.
