e39bf1e2a9 kgdb: cpu/mpc* cpu/74xx: include kgdb.h when needed
Commit cbb0cab1d9 broke some platforms which used kgdb code but
didn't actually include kgdb.h.  So include kgdb.h in all the relevant
traps code.

0f8aa15917 ppc: Use r12 instead of r14 as GOT pointer.
r14 is not supposed to be clobbered by functions. Switch
to r12 and call GET_GOT when needed. This will allow u-boot
to loose the -ffixed-r14 gcc option.

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.

afc3ba0fc4 relocation: Do not relocate NULL pointers.
NULL is an absolute value and should not be relocated.
After this correction code like:
 void weak_fun(void) __attribute__((weak));
 printf("weak_fun:%p\n", weak_fun);
will still print null after relocation.

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.

2b3f12c214 8xx serial, smc: add configurable SMC Rx buffer len
This patch adds the configuration option CONFIG_SYS_SMC_RXBUFLEN.
With this option it is possible to allow the receive
buffer for the SMC on 8xx to be greater then 1. In case
CONFIG_SYS_SMC_RXBUFLEN == 1 this driver works as the
old version.

When defining CONFIG_SYS_SMC_RXBUFLEN also
CONFIG_SYS_MAXIDLE must be defined to setup the maximum
idle timeout for the SMC.

e7670f6c1e PPC: Use r2 instead of r29 as global data pointer
R29 was an unlucky choice as with recent toolchains (gcc-4.2.x) gcc
will refuse to use load/store multiple insns; instead, it issues a
list of simple load/store instructions upon function entry and exit,
resulting in bigger code size, which in turn makes the build for a
few boards fail.

Use r2 instead.

d197ffd817 Fix and optimize MII operations on FEC (MPC8xx) controllers
This patch fixes several issues at least on a MPC885 based system with two
FEC interfaces used in MII mode.

1. PHY discovery should first read PHY_PHYIDR2 register and only then
   PHY_PHYIDR1 like cpu/mpc8xx/fec.c::mii_discover_phy() does it,
   otherwise the values read are wrong. Also notice, that PHY discovery
   cannot work on MPC88x / MPC87x in setups with both FECs active at all
   in its present form, because for both interfaces the registers from FEC
   1 are used to communicate over MII.

2. Remove code duplication for resetting the FEC by isolating it into a
   separate function.

3. Initialize MII on FEC 1 when communicating over FEC 2 in fec_init().

4. Optimize mii_init() to only reset the FEC 1 controller once.

5. Fix a typo in mii_init() using index i instead of j thus potentially
   leading to unpredictable results.

f93286397e Add support for a saving build objects in a separate directory.
Modifications are based on the linux kernel approach and
support two use cases:

  1) Add O= to the make command line
  'make O=/tmp/build all'

  2) Set environement variable BUILD_DIR to point to the desired location
  'export BUILD_DIR=/tmp/build'
  'make'

The second approach can also be used with a MAKEALL script
'export BUILD_DIR=/tmp/build'
'./MAKEALL'

Command line 'O=' setting overrides BUILD_DIR environent variable.

When none of the above methods is used the local build is performed and
the object files are placed in the source directory.

d6cc73e4e7 Bugfix in FEC initialisation:
All MII configuration is done via FEC1 registers. But MII_SPEED was
configured according to FEC used. So if only FEC2 was used, this caused
the real MII_SPEED register in FEC1 to stay uninitalised, what lead
to "mii_send STUCK!" messages. Fix: always configure MII_SPEED on FEC1
only.
