[PATCH 3/3] boards: siemens: iot2050: Unify PG1 and PG2/M.2 configurations again
Jan Kiszka
jan.kiszka at siemens.com
Mon Jun 5 16:39:53 CEST 2023
From: Jan Kiszka <jan.kiszka at siemens.com>
This avoids having to maintain to defconfigs that are 99% equivalent.
The approach is to use binman to generate two flash images,
flash-pg1.bin and flash-pg2.bin. With the help of some macros, we can
avoid duplicating the common binman image definitions.
Suggested-by: Andrew Davis <afd at ti.com>
