Introduce spl_boot_list array, which defines a list of boot devices that SPL will try before hanging. By default this list will consist of only spl_boot_device(), but board_boot_order() can be overridden by board code to populate the array with custom values.

So, a problem with this patch is that we push the x600 board, which is an 8KiB SPL target, over the line. I feel like maybe we need a follow-up patch that makes announcing depend not on libcommon (which x600 needs) but something else to know that there's a reason to announce.
Based on the content of your reply I'm guessing you're referring to the next patch, not this one.
Oh yes, oops.
I suppose that announcing can be made into an optional feature. However, I also think that since printing is an optional feature that can greatly increase binary size, it shouldn't be coupled with other, often non-optional libcommon features the way it currently is via CONFIG_SPL_LIBCOMMON_SUPPORT. The best fix in my opinion would be to implement a way to exclude printing support from SPL even if libcommon is included (CONFIG_SPL_SILENT that replaces printfs with empty stubs?).
This will also make it possible to remove all those #ifdef CONFIG_SPL_LIBCOMMON_SUPPORT checks that appear all over the SPL code.
So the reason I'm thinking that we want this announce thing separate is that (due to the way you re-worked it I think, based on Simons' request) this added a huge amount of space. We went from OK to overflowing by more than 1KiB. So I'm not immediately sure that we can regain that space with a more (space) efficient printing infrastructure.
