Hi -
yes, some OMAP3 problems were fixed in the OMAP4 ROM code based on the
feedback from linux/SD card users.
I think it pretty much reached perfection on OMAP4 for SD boot case
anyway. In fact a VFAT and partition parser in ROM was more than I
expected to see, it's very good.
Of course, it'll pull anything called MLO. I believe folks are
working on adding stuff to be able to call U-Boot "MLO" directly
eliminating x-loader and Matt Hsu and I already did that for Qi.
one clarification: the u-boot MLO project is just about the capabilities
of rebuilding MLO from u-boot sources. in fact MLO is a 'tiny uboot'. so
instead of duplicating the source tree for x-loader as it stands today,
the idea is to have a mlo config in uboot and rebuild this tiny uboot
from uboot sources so that there is no need to maintain 2 MMC driver for
example. you will still get a 2-stage bootloader.
FWIW panda-dev branch of Qi does it in one stage, and it's not that much
bigger than x-loader alone. It just loads and boots linux plus or minus
initrd though so it's not the same as U-Boot.
Yeah confusing ain't it. There are two camps in x-loader
development one on omapzoom and one on gitorious. TI engineers like
omapzoom but the official repo is gitorious.
i don't think it's a TI vs others issue. TI has been pushing for a
Right, I meant, as you can see from the two commit logs, that TI
engineers "like" to push to omapzoom repo and the official one less so.
mailing xloader because there is a lot of confusion on this topic. the
clean mainline tree started after the android xloader and is still
lacking behind. if community/TI is able to bring mainline x-loader to
the same level of features has the omapzoom one, I am pretty sure that
the migration can happen.
I did create a unification branch a while ago which merged all omapzoom
content on to the gitorious one. The result worked fine on Panda, but I
didn't test it on anything else.
