Size of the SDRAM chips might differ between any two (otherwise identical) instances of the same board.
So change board_early_init_f() to use km_sdram_bs_set(), in order to fixup the window size register at runtime, according to the detected SDRAM size.

changes for v2:
- rebase to current u-boot-marvell.git master branch

The name "fixup" doesn't sound good.

- /* probe currently equipped RAM size */
- size = get_ram_size((void *)kw_sdram_bar(0), kw_sdram_bs(0));
- /* fixup SDRAM window size accordingly */
- kw_sdram_bs_set(0, size);
+}
This is useful API for other boards too. I would like to suggest to add this change in dram_init(), the window size can be corrected right after sdram size detection. And that will be applicable for all supported bank.
So may you please push in to dram.c?
