This board definition results in a u-boot.bin which can be chainloaded from NOLO in qemu or on a real N900. It does very little hardware config because NOLO has already configured the board. Only needed is enabling internal eMMC memory via twl4030 regulator which is not enabled by NOLO.

This isn't used.

This isn't correct for disabling L2 now and doesn't do anything. So L2 is probably enabled :)
and #define CONFIG_SYS_L2CACHE_OFF is correct?
Yes.

And I'm not sure if any of these are really needed now.
When I deleted this code, I cannot compile U-Boot. Here is error message: include/asm/u-boot.h:48:17: error: ‘CONFIG_NR_DRAM_BANKS’ undeclared here (not in a function)
I just meant the SDRC_R_B_C part, sorry.
