When the SPL build-phase was first created it was designed to solve a particular problem (the need to init SDRAM so that U-Boot proper could be loaded). It has since expanded to become an important part of U-Boot, with three phases now present: TPL, VPL and SPL
Due to this history, the term 'SPL' is used to mean both a particular phase (the one before U-Boot proper) and all the non-proper phases. This has become confusing.
For a similar reason CONFIG_SPL_BUILD is set to 'y' for all 'SPL' phases, not just SPL. So code which can only be compiled for actual SPL, for example, must use something like this:
#if defined(CONFIG_SPL_BUILD) && !defined(CONFIG_TPL_BUILD)
In Makefiles we have similar issues. SPL_ has been used as a variable which expands to either SPL_ or nothing, to chose between options like CONFIG_BLK and CONFIG_SPL_BLK. When TPL appeared, a new SPL_TPL variable was created which expanded to 'SPL_', 'TPL_' or nothing. Later it was updated to support 'VPL_' as well.
This series starts a change in terminology and usage to resolve the above issues:
- The word 'xPL' is used instead of 'SPL' to mean a non-proper build - A new CONFIG_XPL_BUILD define indicates that the current build is an 'xPL' build - The existing CONFIG_SPL_BUILD is changed to mean SPL; it is not now defined for TPL and VPL phases - The existing SPL_ Makefile variable is renamed to SPL_ - The existing SPL_TPL Makefile variable is renamed to PHASE_
It should be noted that xpl_phase() can generally be used instead of the above CONFIGs without a code-space or run-time penalty.
This series does not attempt to convert all of U-Boot to use this new terminology but it makes a start. In particular, renaming spl.h and common/spl seems like a bridge too far at this point.
The series is fully bisectable. It has also been checked to ensure there are no code-size changes on any commit.
Changes in v3: - Correct the subject to match what the patch changed to do - Don't update to use SPL_BUILD in the SPL check - Drop the change in Makefile.xpl since XPL is already defined - Move earlier in the series - Move to earlier in the series - Split into several patches - Squash in 'x86: Update a comment to mention XPL'
Changes in v2: - Drop patches not stricly necessary for the conversion - Move to earlier in the series - Rebase to -next - Update cover letter re code size
