Subject: [PATCH] avr32/m68k/microblaze/nds32/nios2/openrisc/sh/sparc: fix
do_bootm_linux
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

Commit 35fc84fa1ff51e15ecd3e464dac87eb105ffed30 broke bootm on avr32. It
requires to call do_bootm_linux() with flag set to BOOTM_STATE_OS_PREP before
calling it again with flag set to BOOTM_STATE_OS_GO.
Fix this by allowing flag set to BOOTM_STATE_OS_PREP, this however will
require a complete refactoring later on.
