But no CONFIG_CMD_FS_GENERIC ?

+#define CONFIG_MAX_RAM_BANK_SIZE	(1024 << 20)	/* 1GB */

Please just use 0x80000000 directly in later defines, or CONFIG_SYS_SDRAM_BASE in code.

Quoted 1 line

+#define CONFIG_SPL_NET_VCI_STRING "AM335x U-Boot SPL"

I would strongly encourage "nanobone" somewhere in this string, so that you don't feed the binary for an am335x_evm.h-based board to this board. Or drop if you aren't really supporting SPL via USB or ethernet.

Quoted 2 lines
include/configs/nanobone.h new file +2 -0
+/* Unsupported features */
+#undef CONFIG_USE_IRQ

[snip]

Quoted 1 line

+#define CONFIG_BOOTP_DEFAULT

Unused.

And I realize everything but the VCI string and lack of CONFIG_CMD_FS_GENERIC is inherited from am335x_evm.h, I'm working on a series to fix that now.
