[U-Boot] [PATCH] lib_arch/board.c: Move malloc initialization before flash_init()

Stefan Roese sr at denx.de
Mon May 11 15:50:12 CEST 2009


This patch moves the malloc initialization before calling flash_init().
Upcoming changes to the NOR FLASH common CFI driver with optional
MTD infrastructure and MTD concatenation support will call malloc().
And nothing really speaks against enabling malloc just a little earlier
in the boot stage. Some architectures already enable malloc before
calling flash_init() so they don't need any changes here.

If nobody from the platforms custodians objects against this patch
then I suggest that Wolfgang pulls it directly into next.

Thanks,
Stefan
