From 54193c5d8133f4f35267f412e5c1bbcbc6ac041c Mon Sep 17 00:00:00 2001 From: Sergei Shtylyov Date: Fri, 3 Jun 2011 09:37:43 +0000 Subject: part_dos: fix crash with big sector size Apple iPod nanos have sector sizes of 2 or 4 KiB, which crashes U-Boot when it tries to read the MBR into 512-byte buffer situated on stack. Instead use the variable length arrays to be safe with any large sector size.
