From mboxrd@z Thu Jan 1 00:00:00 1970 From: anarsoul@gmail.com (Vasily Khoruzhick) Date: Tue, 11 May 2010 09:55:09 +0300 Subject: [PATCH v2 3/5] Locate kernel at 0x30108000 if PM_H1940 is enabled In-Reply-To: <1273560911-18153-1-git-send-email-anarsoul@gmail.com> References: <1273560911-18153-1-git-send-email-anarsoul@gmail.com> Message-ID: <1273560911-18153-4-git-send-email-anarsoul@gmail.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org If PM_H1940 is enabled, kernel _must_ be located upper then 0x30008000, because this area (0x30000000-0x30100000) can be used by bootloader. If kernel is located at 0x30008000, bootloader will corrupt kernel's code during resume.
