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.
