[PATCH v2 0/8] spl: binman: Fixes for BINMAN_SYMBOLS

[Alper Nebi Yasak]

There's some trouble with an i.MX8M series [1] trying to use binman
symbols. The crux of it is the 'u_boot_any' symbols BINMAN_SYMBOLS
configs declare, and the boards creating partial binman images including
an SPL without a U-Boot the symbol is referring to.

Normally this should be easy to resolve by disabling BINMAN_SYMBOLS
configs, but that causes a build error. Apparently some parts of the SPL
code (RAW_IMAGE_SUPPORT, RAM_DEVICE) use the symbols directly without
guarding them by BINMAN_SYMBOLS, implicitly requiring it.

The first patch fixes the issue above, the rest are related things I
tinkered with while trying to understand the issue and the i.MX8M use
case. Part of this is splitting binman symbols support from enabling
binman and from the u-boot-any symbols declarations. Another is to add a
new macro people can use to check if they can use binman symbols safely.

These apply onto u-boot/next. I have also triggered an Azure CI run [2]
via a Github pull request.
