4b99327a41 PPC: Record U-Boot's relocated address in RAM and show in bdinfo.
This patch uses gd->relocaddr variable to store uboot's relocated
address in RAM and shows it in bdinfo command.

This patch moves CONFIG_AMIGAONEG3SE style copying of the address
in board_init_f to just before relocation is actually done.

fc4e188789 ppc: Loose GOT access in IRQ
Using the GOT in IRQ handlers requires r14 to be -ffixed-r14.
Avoid this by relocatate transfer_to_handler too.
This will allow to free up r14 later on.

82826d5422 mpc512x: Add display of reset status register
Content of the RSR is put into gd early so we can output it together
with the CPU info.  The clearing of gd in board_init_f is redundant for
this architecture as it is done in cpu_init_f so we remove it.

f9476902b7 mpc85xx, mpc86xx: Fix gd->cpu pointer after relocation
The gd->cpu pointer is set to an address located in flash when the
probecpu() function is called while U-Boot is executing from flash.
This pointer needs to be updated to point to an address in RAM after
relocation has occurred otherwise Linux may not be able to boot due to
"fdt board" crashing if flash has been erased or changed.

This bug was introduced in commit
a0e2066f39.

3eb90bad65 Generic udelay() with watchdog support
According to the PPC reference implementation the udelay() function is
responsible for resetting the watchdog timer as frequently as needed.
Most other architectures do not meet that requirement, so long-running
operations might result in a watchdog reset.

This patch adds a generic udelay() function which takes care of
resetting the watchdog before calling an architecture-specific
__udelay().

91525c6715 mpc85xx: Fix booting on various boards
commit 0e870980a6 ("8xxx: Removed
CONFIG_NUM_CPUS from 85xx/86xx") breaks U-Boot on various boards,
namely the ones that call get_sys_info() from board_early_init_f().

get_sys_info() calls cpu_numcores(), which depends on probecpu()
being called before. But probecpu() is called after board_early_init_f(),
and so cpu_numcores() returns random values, which in turn crashes
get_sys_info().

To fix the issue we place probecpu() before board_early_init_f()
in an initialization sequence.

Booting on the following boards should be revived now:
 mpc8540ads
 mpc8541cds
 mpc8548cds
 mpc8555cds
 mpc8560ads
 mpc8568mds
 mpc8569mds
 and maybe more.

Certain ppc compilers are known not to generate the .fixup section

982adfc610 ppc: Unlock cache-as-ram in a consistent manner
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.

52cb4d4fb3 stdio/device: rework function naming convention
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.

c790b04d23 lib_arch/board.c: Move malloc initialization before flash_init()
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.

eb85aa594c ppc: mark global bi_enet*addr as legacy
The environment is the canonical storage location of the mac address, so
we're killing off the global data location and moving everything to

In the ppc case, these things are part of the legacy ABI, so keep them

Also stop calling load_sernum_ethaddr() since all boards now implement
this as a stub.
