32749e91aa serial: arm_dcc: Remove stdio structure support
Removed stdio structure ops support on arm_dcc
driver, and need to register with serial core

e70fb539a6 serial: arm_dcc: Remove CONFIG_ARM_DCC_MULTI option
CONFIG_ARM_DCC_MULTI should be also removed in the patch
"serial: Remove CONFIG_SERIAL_MULTI from serial drivers"
(sha1: a382725060)
Because the driver defines serial_* functions
which cause conflict with serial.c (multiple definition of serial_*)

Removing CONFIG_SERIAL_MULTI function also require to define
default_serial_console for cases where another serial driver
is not available in the system.

6a135efcd0 stdio: remove useless strncpy
The name is already copied when we memcpy() the whole structure.

This is because struct stdio_dev has this field:

	char	name[16];		/* Device name				*/

So the data is inline, rather than being a pointer.

98ab435f73 x86: Add CBMEM console driver for coreboot
This patch builds upon the recently introduced CBMEM console
feature of coreboot.

CBMEM console uses a memry area allocated by coreboot to store
the console output. The memory area has a certain structure,
which allows to determine where the buffer is, the buffer size
and the location of the pointer in the buffer. This allows
different phases of the firmware (rom based coreboot, ram based
coreboot, u-boot after relocation with this change) to keep
adding text to the same buffer.

Note that this patch introduces a new console driver and adds the
driver to the list of drivers to be used for console output, i.e.
it engages only after u-boot relocates. Usiong CBMEM console for
capturing the pre-relocation console output will be done under a
separate change.

>From Linux, run the cbmem.py utility (which is a part of the coreboot
package) to see the output, e.g.:

vvvvvvvvvvvvvvvvv
SCSI:  AHCI 0001.0300 32 slots 6 ports ? Gbps 0xf impl SATA mode
flags: 64bit ilck stag led pmp pio
...
Magic signature found
Kernel command line: "cros_secure  quiet loglevel=1 console=tty2...
^^^^^^^^^^^^^^^^^

Note that the entire u-boot output fits into the buffer only if
the coreboot log level is reduced from the most verbose. Ether
the buffer size will have to be increased, or the coreboot
verbosity permanently reduced.

or ifdefs around CONFIG_SERIAL_MULTI parts since CONFIG_SERIAL_MULTI

2e5167ccad Replace CONFIG_RELOC_FIXUP_WORKS by CONFIG_NEEDS_MANUAL_RELOC
By now, the majority of architectures have working relocation
support, so the few remaining architectures have become exceptions.
To make this more obvious, we make working relocation now the default
case, and flag the remaining cases with CONFIG_NEEDS_MANUAL_RELOC.

24956642ef Remove unused CONFIG_SERIAL_SOFTWARE_FIFO feature
This patch removes the completely unused CONFIG_SERIAL_SOFTWARE_FIFO
feature from U-Boot. It has only been implemented for PPC4xx and was not
used at all. So let's remove it and make the code smaller and cleaner.

0630535e2d arm/microblaze/nios/nios2/sh: Remove relocation fixups
These architectures don't need relocation fixups, so reduce their
codesize a bit by defining CONFIG_RELOC_FIXUP_WORKS.

Also remove the reloc_off field from their global data structures
as it is no longer needed.

Note that the location of the standalone application jump table pointer
in the global data structure is affected by this change, breaking
execution of standalone applications compiled for previous versions of
U-Boot. We will therefore increment XF_VERSION in the next commit,
which also touches this area.

521af04d85 Conditionally perform common relocation fixups
Add #ifdefs where necessary to not perform relocation fixups.  This
allows boards/architectures which support relocation to trim a decent
chunk of code.

Note that this patch doesn't add #ifdefs to architecture-specific code
which does not support 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.
