Hi Aneesh, I recently started to work on a similar topic: omap3 (devkit8000) nand_spl support. So I'am really interested in your OMAP4/common work here ;)
In this patch comment you say its common for OMAP3/4 but in preloader_console_init() is a call to omap4_rev_string()): > printf("Texas Instruments %s\n", omap4_rev_string()); Regards Simon 2011/5/15 Aneesh V <ane...@ti.com> > Add the basic spl framework and linker script common for OMAP3/4 > platforms. > > Signed-off-by: Aneesh V <ane...@ti.com> > --- > spl/board/ti/spl-omap.c | 47 ++++++++++++++++++++++++++++++++++ > spl/board/ti/spl-omap.lds | 62 > +++++++++++++++++++++++++++++++++++++++++++++ > 2 files changed, 109 insertions(+), 0 deletions(-) > create mode 100644 spl/board/ti/spl-omap.c > create mode 100644 spl/board/ti/spl-omap.lds > > diff --git a/spl/board/ti/spl-omap.c b/spl/board/ti/spl-omap.c > new file mode 100644 > index 0000000..0e08f4f > --- /dev/null > +++ b/spl/board/ti/spl-omap.c > @@ -0,0 +1,47 @@ > +/* > + * > + * Clock initialization for OMAP4 > + * > + * (C) Copyright 2010 > + * Texas Instruments, <www.ti.com> > + * > + * Aneesh V <ane...@ti.com> > + * > + * See file CREDITS for list of people who contributed to this > + * project. > + * > + * This program is free software; you can redistribute it and/or > + * modify it under the terms of the GNU General Public License as > + * published by the Free Software Foundation; either version 2 of > + * the License, or (at your option) any later version. > + * > + * This program is distributed in the hope that it will be useful, > + * but WITHOUT ANY WARRANTY; without even the implied warranty of > + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
