[U-Boot] [PATCH v4 7/8] x86: qemu: adjust ramdisk load address

[Miao Yan]

By default, ramdisk load address is defined to 02000000 in
env string. When loading bzImage to 100000 (default address), there's
a chance that the ramdisk header would be overwritten by
the kernel. Thus increase the gap and make ramdisk load at 04000000
by default.
