You should possibly CC this mail into u-boot mailing list too.
Ok I hereafter I will do it.

Do you have correct GPIO mux settings ? In this case GPIO80 as to be AF2, check
your GAFRx registers.
#define CONFIG_SYS_GAFR2_U_VAL 0x4109a401, which means GPIO80 is assigned AF2 for nCS4.

Are you sure about the 0x300 offset? That's actually toggling MA<10:9> pins on.
Do you have these connected at all?
I really don't know what for the offset 0x300.
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.
Yes not required.

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.
Ok, I will remove it.
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
Already done it.

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.
