You should possibly CC this mail into u-boot mailing list too.

Do you have correct GPIO mux settings ? In this case GPIO80 as to be AF2, check 
your GAFRx registers.

Are you sure about the 0x300 offset? That's actually toggling MA<10:9> pins on. 
Do you have these connected at all?

Try this:

+/*
+ * Networking Configuration
+ * SMC91C111 chip
+ */
+#ifdef CONFIG_CMD_NET
+#define        CONFIG_CMD_PING
+#define        CONFIG_CMD_DHCP
+#define        CONFIG_NET_MULTI
+
+#define        CONFIG_SMC91111
+#define        CONFIG_SMC91111_BASE    0x10000300
+
+#define        CONFIG_BOOTP_BOOTFILESIZE
+#define        CONFIG_BOOTP_BOOTPATH
+#define        CONFIG_BOOTP_GATEWAY
+#define        CONFIG_BOOTP_HOSTNAME
+
+#define        CONFIG_NETMASK                  255.255.255.0
+#define        CONFIG_IPADDR                   192.168.1.52
+#define        CONFIG_SERVERIP                 192.168.1.51
+#endif

You don't need these ... see arch/arm/include/asm/arch-pxa/macro.h, everything 
you need is already configured there. Check for example vpac270 board.

You don't need that. The macros above do it for you. Again, check vpac270 board, 
it's lowlevel_init.S, it's configs/vpac270.h etc. You'll see that these are 
configured much earlier and you're only duplicating work.

All you need in your hclpxa270.c is this:

+#ifdef CONFIG_CMD_NET
+int board_eth_init(bd_t *bis)
+{
+       int rc = 0;
+#ifdef CONFIG_SMC91111
+       rc = smc91111_initialize(0, CONFIG_SMC91111_BASE);
+#endif
+       return rc;
+}
+#endif

You should CC the mailing list anyway, because the knowledge I share with you 
can help other people who will search the mailing list in future.

Also, could you share your patch for the hcl board? It might be easier to check 
for grave bugs then.
