Do you mean like this?

--- a/cmd/net.c
+++ b/cmd/net.c
@@ -244,6 +244,8 @@ static int netboot_common(enum proto_t proto, cmd_tbl_t *cmd
        }

        /* flush cache */
+       load_addr &= ~(CONFIG_SYS_CACHELINE_SIZE - 1);
+       size = ALIGN(size, CONFIG_SYS_CACHELINE_SIZE);
        flush_cache(load_addr, size);

        bootstage_mark(BOOTSTAGE_ID_NET_LOADED);

This makes the net warnings go away.

There is still this one that I am seeing:

Kernel image @ 0x80800000 [ 0x000000 - 0x6fea70 ]
## Flattened Device Tree blob at 83000000
   Booting using the fdt blob at 0x83000000
   Using Device Tree in place at 83000000, end 83009c5d

Starting kernel ...

CACHE: Misaligned operation at range [00900000, 00900529]
[    0.000000] Booting Linux on physical CPU 0x0

Any ideas where it may come from?

Thanks
