Subject: [PATCH v2 3/5] Locate kernel at 0x30108000 if PM_H1940 is enabled
Date: Tue, 11 May 2010 09:55:09 +0300 [thread overview]
Message-ID: <1273560911-18153-4-git-send-email-anarsoul@gmail.com> (raw)
In-Reply-To: <1273560911-18153-1-git-send-email-anarsoul@gmail.com>
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.
