What was suppose to be a stack variable was declared as a pointer,
overwriting random memory.
Also moved the libfdt.a requirement into the main Makefile. That is
The U-Boot Way.

U-Boot part of Lite5200b low power mode support.
Puts SDRAM out of self-refresh and transfers control to

Set up the portmux for the MMC interface and enable the MMC driver
along with support for DOS partitions, ext2 and FAT filesystems.

Implement MACB initialization for AVR32 and ATSTK1000, and turn
everything on, including the MACB driver.

Conform to the "standard" interface and use initdram() instead of
board_init_memories() on AVR32. This enables us to get rid of the
sdram_size member of the global_data struct as well.

Relocate the u-boot image into SDRAM like everyone else does. This
means that we can handle much larger .data and .bss than we used to.

Rewrite the resource management code (i.e. I/O memory, clock gating,
gpio) so it doesn't depend on any global state. This is necessary
because this code is heavily used before relocation to RAM, so we
can't write to any global variables.
As an added bonus, this makes u-boot's memory footprint a bit smaller,
although some functionality has been left out; all clocks are enabled
all the time, and there's no checking for gpio line conflicts.

Move the 8641HPCN's PIXIS code to the new directory
board/freescale/common/ as it will be shared by
future boards not in the same processor family.
Write a "pixis_reset" command that utilizes the FPGA
reset sequencer to support alternate soft-reset options
such as using the "alternate" flash bank, enabling
the watch dog, or choosing different CPU frequencies.
Add documentation for the pixis_reset to README.mpc8641hpcn.

...in preparation for improving the bootm command's handling of fdt blobs.
Also cleaned up some coding sloppiness.

With this new base address of the Xilinx SystemACE controller
the Linux driver will be easier to adapt, since it can now be
mapped via the "normal" ioremap() call.

The board specific "bootstrap" command is now fixed and can
be used for the AMCC Katmai board to configure different

This patch adds some 4xx GPIO functions. It also moves some of the
common code and defines into a common 4xx GPIO header file.
