I use (a pretty old version of, but I doubt that matters) RPi
Foundation's Raspbian image, and compiled the kernel and U-Boot
according to:
http://elinux.org/index.php?title=RPi_Upstream_Kernel_Compilationoldid=351104
http://elinux.org/RPi_U-Boot
I installed the Raspbian image but I don't get uImg.txt nor the same
boot sequence. I am able to boot a kernel though.
The RPi Foundation images boot their kernel directly from their binary
firmware, and hence don't include any U-Boot or U-Boot boot scripts.
I haven't used boot.scr for a while, but this is apparently what's in mine:
load ${devtype} ${devnum}:1 ${kernel_addr_r} /zImage
load ${devtype} ${devnum}:1 ${fdt_addr_r} /${fdtfile}
setenv bootargs earlyprintk loglevel=8 console=ttyAMA0 console=tty1 \
verbose rootwait root=/dev/mmcblk0p2 rw
bootz ${kernel_addr_r} - ${fdt_addr_r}
I use extlinux/extlinux.conf now, with the following content:
TIMEOUT 100
DEFAULT default
MENU TITLE Boot menu
LABEL default
MENU LABEL Default kernel
LINUX ../zImage
FDTDIR ../
APPEND earlyprintk loglevel=8 console=ttyAMA0 console=tty1 verbose \

LABEL fallback
MENU LABEL Backup kernel
LINUX ../backup/zImage
FDTDIR ../backup/
APPEND earlyprintk loglevel=8 console=ttyAMA0 console=tty1 verbose \

(in both cases, the continuation lines are all on one line; I only split
them for email purposes)

[U-Boot] [PATCH 0/4] dm: rpi: Move Raspberry Pi to use driver model
This series adds driver model support to the GPIO and serial drivers used
by Raspberry Pi, and moves Raspberry Pi over to driver model.
This requires adding driver model support to the pl01x serial driver, and
replacing the bcm2835 GPIO driver with a driver model version (since there
are no longer clients that don't use driver model).
See u-boot-dm.git branch rpi-working for the tree this is based on.
