This reverts commit 982adfc610669482a32127282fe489857a92cfe3.
This patch causes problems on MPC83xx boards - flash recognition stops
working.

Previously, non-e500 architectures only unlocked their data cache which
was used as early RAM when booting to Linux using the "bootm" command.
This change causes all PPC boards with CONFIG_SYS_INIT_RAM_LOCK defined
to unlock their data cache during U-Boot's initialization. This
improves U-Boot performance and provides a common cache state when
booting to different OSes.

This cleans up U-Boot's toplevel directory a bit and makes the

So far the console API uses the following naming convention:
======Extract======
typedef struct device_t;
int device_register (device_t * dev);
int devices_init (void);
int device_deregister(char *devname);
struct list_head* device_get_list(void);
device_t* device_get_by_name(char* name);
device_t* device_clone(device_t *dev);
=======
which is too generic and confusing.
Instead of using device_XX and device_t we change this
into stdio_XX and stdio_dev
This will also allow to add later a generic device mechanism in order
to have support for multiple devices and driver instances.

This patch moves the malloc initialization before calling flash_init().
Upcoming changes to the NOR FLASH common CFI driver with optional
MTD infrastructure and MTD concatenation support will call malloc().
And nothing really speaks against enabling malloc just a little earlier
in the boot stage. Some architectures already enable malloc before
calling flash_init() so they don't need any changes here.

Some systems have zlib.h installed in /usr/include/. This isn't the

We had a bug on 86xx in which the boot page used to bring up secondary
cores was being overwritten and used for the malloc region in u-boot.
We need to reserve the region of memory that the boot page is going to
be put at so nothing uses it.

The environment is the canonical storage location of the mac address, so
we're killing off the global data location and moving everything to
querying the env directly.
In the ppc case, these things are part of the legacy ABI, so keep them
around but mark them as legacy so no new code will touch them.
Also stop calling load_sernum_ethaddr() since all boards now implement
this as a stub.

The environment is the canonical storage location of the mac address, so
we're killing off the global data location and moving everything to
querying the env directly.
Rather than have common ppc code call a board-specific function like
load_sernum_ethaddr(), have each board call it in its own board-specific
misc_init_r() function.
The boards that get converted here are:
- kup4k/kup4x
- pcs440ep
- tqm8xx

For the nx823, the serial number is moved out of load_sernum_ethaddr() and
into misc_init_r() as is the env setup. This lets us kill off the former
function in the process.

Here's a new framework (based roughly off the linux one) for managing
MMC controllers. It handles all of the standard SD/MMC transactions,
leaving the host drivers to implement only what is necessary to
deal with their specific hardware.
This also hooks the infrastructure into the PowerPC board code
(similar to how the ethernet infrastructure now hooks in)

If we call flush_cache(0xfffff000, 0x1000) it would never
terminate the loop since end = 0xffffffff and we'd roll over

Rather than have the board code initialize SATA automatically during boot,
make the user manually run "sata init". This brings the SATA subsystem in
line with common U-Boot policy.
Rather than having a dedicated weak function "is_sata_supported", people
can override sata_initialize() to do their weird board stuff. Then they
can call the actual __sata_initialize().

Doing trap_init immediately once we're running from RAM
means we're no longer dependent on the physical location of
the flash on non-BookE platforms. Before trap_init, those
platforms switch to real mode and go to 0xfff00100 on exception.
After the switch, they go to 0x00000100 This makes it easier to
move the flash location.

Add the ability to break the steps of the bootm command into several
subcommands: start, loados, ramdisk, fdt, bdt, cmdline, prep, go.
This allows us to do things like manipulate device trees before
they are passed to a booting kernel or setup memory for a secondary
core in multicore situations.
Not all OS types support all subcommands (currently only start, loados,
ramdisk, fdt, and go are supported).

Commit 2a1a2cb6 didnt remove the dummy mem reservation in fdt_chosen,
and this stopped Linux from booting with a Ramdisk. This patch fixes
this, by deleting the useless dummy mem reservation.
When booting with a Ramdisk, a fix offset FDT_RAMDISK_OVERHEAD is now
added to of_size, so we dont need anymore a dummy mem reservation.
I measured the value of FDT_RAMDISK_OVERHEAD on a MPC8270 based
system (=0x44 bytes) and rounded it up to 0x80).

There is no need for each OS specific function to call do_reset() we
can just do it once in bootm. This means its feasible on an error for
the OS boot function to return.
Also, remove passing in cmd_tbl_t as its not needed by the OS boot
functions. flag isn't currently used but might be in the future so
we left it alone.
