Hi,
We have the term 'SPL', which has a dual meaning. It is both a particular phase of U-Boot (the one that loads U-Boot proper) and a generic name for any pre-proper phase.
You can see that in a few areas, but for example CONFIG_SPL_BUILD is enabled for TPL and VPL builds, not just SPL.
I propose to rename the generic term from SPL to xPL (meaning any PL phase), leaving SPL to just refer to the phase before U-Boot proper.
The symbol would be CONFIG_XPL but in documentation we would talk of xPL, with a lower-case X, so it is more obvious that it refers to any phase.
What do you think?
I still worry this is just another part of the long symptom of needing to re-work how we configure / build as we have 1 case of "build things this way" (full U-Boot) and N cases of "build things another way" (SPL, TPL, VPL, UPL?). And really we need a way to short-hand "fooboard_defconfig" means "fooboard_spl_defconfig + fooboard_tpl_defconfig + fooboard_SOMETHING_defconfig".
But on the flip side, I also suppose replacing CONFIG_SPL_BUILD with CONFIG_XPL_BUILD would be less confusing.
