Re: [U-Boot] [PATCH] env: don't generate callback list entries for SPL

SPL doesn't use the environment. These list entries prevent the functions from being garbage-collected, even though nothing will look at the list. This caused several SPL builds (e.g. P2020RDB-PC_NAND) to break due to size limitations.

SPL with networking support uses the environment, so you need to toss CONFIG_SPL_NET_SUPPORT into the test. That said, it's not an interactive environment and this might push that area over the size limit too (in the USB case, which is already pretty tight).
