Hi Fabio,


I understand, from the MAINTAINERS file list, that you are the
maintainer for the mx53ard board.  I took a copy of the u-boot sources
for the Freescale SABRE Automotive Infotainment board (aka mx53ard
board) from the Freescale site.  As the result I got the u-boot-2009.08
building tree directory along with the associated cross compiler
gcc-4.4.4-glibc-2.11.1-multilib-1.0-1.386 tools.


After some trial and error I managed to configure the mx53_ard_dd3.h for
NAND and YAFFS2 support and successfully ran make, resulting in creation
of the following files:

*         u-boot

*         u-boot.bin

*         u-boot.srec

*         u-boot.map

*         u-boot.lds


However, I would want to initially boot from SD-card and I would like to
be able to generate an imx image of the u-boot when running make.  I
looked at the Makefile from the Freescale release of u-boot-2009.08 and
saw that it is fairly outdated - it does not support making of
u-boot.imx image.  At the same time I see that the general denx
distribution (u-boot-2011.12) of u-boot sources does have the support
for making u-boot.imx image in its Makefile.  So I am wondering if a
patch that can be applied to the u-boot-2009.08 Freescale u-boot source
that will bring the make tools up to date and able to make u-boot.imx
file does exist?


Failing that, is there another way to configure the denx u-boot-2011.12
release to support NAND and YAFFS2 and thus, by successfully compiling,
generate a u-boot.imx image file.
