From mboxrd@z Thu Jan 1 00:00:00 1970 From: =?UTF-8?q?Beno=C3=AEt=20Th=C3=A9baudeau?= Date: Wed, 6 Mar 2013 19:59:30 +0100 Subject: [U-Boot] [PATCH v9 24/30] imx: Add u-boot-with-nand-spl.imx make target In-Reply-To: <1362596377-5827-1-git-send-email-benoit.thebaudeau@advansee.com> References: <1362596377-5827-1-git-send-email-benoit.thebaudeau@advansee.com> Message-ID: <1362596377-5827-24-git-send-email-benoit.thebaudeau@advansee.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de This image combines the SPL with the i.MX header, the FCB and U-Boot. For i.MX25/35/51, the FCB is ignored by the boot ROM, so this image is just useful because it can be programmed on a NAND Flash page boundary. For i.MX53, the FCB is required by the boot ROM. This does not support i.MX6 so far because its FCB is more complicated. Signed-off-by: Beno?t Th?baudeau --- Changes in v9: None Changes in v8: - Change the dummy 1024-byte header into a true FCB in order to add support for i.MX53. - Use CONFIG_SPL_PAD_TO instead of CONFIG_SPL_MAX_SIZE for padding, which allows to pad the SPL after adding the i.MX header and the FCB, which may save time when the boot ROM loads the SPL. - Add /u-boot-with-nand-spl.imx to .gitignore. Changes in v7: - New patch.
