[PATCH v5 02/22] arm: at91: refactor lowlevel_init selection
Sam Ravnborg
sam at ravnborg.org
Sat Jan 6 13:10:58 PST 2018
The aim with this conversion is to drop the dependency
where the mach-at91/ code call code in the boards file.
This dependency must be dropepd to enable multi-image builds.
The selection of lowlevel_init functions are pushed to
the individual boards.
Use AT91SAM926X_BOARD_INIT for the boards that share the
at91sam926x_board_init file, and push this to the
individual boards. To be used in follow-up patches
bootstrap is likewise pushed out to the individual boards.
