Subject: [PATCH]: Allow plat_map_dma_mem_page to take a 'size' argument
Date: Sun, 22 Jul 2007 21:58:28 -0400	[thread overview]
Message-ID: <46A40B44.6020406@gentoo.org> (raw)


This patch enables the plat_map_dma_mem_page function to take a 'size' argument 
for use by machines if needed (IP30 support will need this available).

Signed-off-by: Joshua Kinard <kumba@gentoo.org>
