Merge branch 'master' of git://git.denx.de/u-boot into master

Conflicts:
	drivers/power/power_fsl.c
	include/configs/mx35pdk.h
	include/configs/mx53loco.h
	include/configs/woodburn_common.h
	board/woodburn/woodburn.c

These boards still use the old old PMIC framework, so they
do not merge properly after the power framework was merged into
mainline.

Fix all conflicts and update woodburn to use Power Framework.

+A3M071 board support
+------------------------------------------------------------------------
+
+
+SPL NOR flash support:
+----------------------
+To boot fast into the OS (Linux), this board port integrates the SPL
+framework. This means, that a special, stripped-down version of
+U-Boot runs in the beginning. In the case of the A3M071 board, this
+SPL U-Boot version is less than 16 KiB big. This SPL U-Boot can either
+boot the OS (Linux) or a "real", full-blown U-Boot. This detection
+on whether to boot Linux or U-Boot is done by using the "boot_os"
+environment variable. If "boot_os" is set to "yes", Linux will be
+loaded and booted from the SPL U-Boot version. Otherwise, the
+full-blown U-Boot version will be loaded and run.
+
+Enabling Linux booting:
+-----------------------
+From U-Boot:
+=> setenv boot_os yes
+=> saveenv
+
+From Linux:
+$ fw_setenv boot_os yes
+
+Enabling U-Boot booting:
+------------------------
+From U-Boot:
+=> setenv boot_os no
+=> saveenv
+
+From Linux:
+$ fw_setenv boot_os no
+
+
+Preparing Linux image(s) for booting from SPL U-Boot:
+-----------------------------------------------------
+To boot the Linux kernel from the SPL, the DT blob (fdt) needs to get
+prepard/patched first. U-Boot usually inserts some dynamic values into
+the DT binary (blob), e.g. autodetected memory size, MAC addresses,
+clocks speeds etc. To generate this patched DT blob, you can use
+the following command:
+
+1. Load fdt blob to SDRAM:
+=> tftp 1800000 a3m071/a3m071.dtb
+
+2. Set bootargs as desired for Linux booting (e.g. flash_mtd):
+=> run mtdargs addip2 addtty
+
+3. Use "fdt" commands to patch the DT blob:
+=> fdt addr 1800000
+=> fdt boardsetup
+=> fdt chosen
+
+4. Display patched DT blob (optional):
+=> fdt print
+
+5. Save fdt to NOR flash:
+=> erase fc060000 fc07ffff
+=> cp.b 1800000 fc060000 10000
+
+All this can be integrated into an environment command:
+=> setenv upd_fdt 'tftp 1800000 a3m071/a3m071.dtb;run mtdargs addip2 addtty; \
+	fdt addr 1800000;fdt boardsetup;erase fc060000 fc07ffff; \
+	cp.b 1800000 fc060000 10000'
+=> saveenv
+
+After this, only "run upd_fdt" needs to get called to load, patch
+and save the DT blob into NOR flash.
+
+Additionally, the Linux kernel image has to be saved uncompressed in
+its uImage file (and not gzip compressed). This can be done with this
+command:
+
+$ mkimage -A ppc -O linux -T kernel -C none -a 0 -e 0 \
+	-n "Linux Kernel Image" -d vmlinux.bin uImage.uncompressed
