In order to load u-boot on the QT2410 with JTAG, a few changes are
1) add lowlevel_foo_qt2410.patch
2) include/configs/qt2410.h needs CONFIG_LL_INIT_NAND_ONLY
3) Use the following, modified load procedure:
load_binary ../u-boot/board/qt2410/lowlevel_foo.bin 0
bp 0x33f80000 4 hw
load_binary ../u-boot/u-boot.bin 0x33f80000
# takes about one minute
(The change is in the location of lowlevel_foo.)
lowlevel_foo_qt2410.patch is a little ugly, because it duplicates a
lot of material from board/neo1973/gta*/Makefile, but cleaning that
up would need some redesign of how lowlevel_foo is built in general,
which is something I don't want to touch now.
The addition of CONFIG_LL_INIT_NAND_ONLY should break booting from
NOR (which I think nobody in the OpenMoko project uses), so that's
not a change suitable for mainstream.
Harald, would you agree if I merge lowlevel_foo_qt2410.patch "as is"
into lowlevel_foo.patch and add CONFIG_LL_INIT_NAND_ONLY through
some openmoko-qt2410-setup.patch ?
