[PATCH] ARM: OMAP1: ams-delta: clean up init data section assignments

Janusz Krzysztofik jkrzyszt at tis.icnet.pl
Thu Feb 9 06:18:22 EST 2012


The main purpose of this patch is to fix several section mismatch
warnings from the board file and a few board specific drivers,
introduced mostly with recent Amstrad Delta patch series, some of them
rising up only when building with CONFIG_MODULES not set.

While being at it, section assignments of all init data found in the
board file have been revised and hopefully optimised.

Created and tested on top of current linux-omap/omap1, commit
967809bd7faf71ddc29c8081e0f21db8b201a0f4.
