d9abba8254 Add generic support for samsung s3c2440
This patch adds generic support for the Samsung s3c2440 processor.

Global s3c24x0 changes to struct members converting from upper case to
lower case.

ac67804fbb Add a unified s3c24x0 header file
This patch adds a unified s3c24x0 cpu header file that selects the header
file for the specific s3c24x0 cpu from the SOC and CPU configs defined in
board config file. This removes the current chain of s3c24-type #ifdef's
from the s3c24x0 code.

492fb1fdbc Move s3c24x0 header files to asm-arm/arch-s3c24x0/
This patch moves the s3c24x0 header files from include/ to
include/asm-arm/arch-s3c24x0/.

checkpatch.pl showed 2 errors and 3 warnings. The 2 errors were both due
to a non-UTF8 character in David M?ller's name:

ERROR: Invalid UTF-8, patch and commit message should be encoded in UTF-8
#489: FILE: include/asm-arm/arch-s3c24x0/s3c2410.h:3:
+ * David M?ller ELSOFT AG Switzerland. d.mueller@elsoft.ch

As David's name correctly contains a non-UTF8 character I haven't fixed
these errors.

The 3 warnings were all because of the use of 'volatile' in s3c24x0.h:

WARNING: Use of volatile is usually wrong: see Documentation/volatile-considered-harmful.txt
#673: FILE: include/asm-arm/arch-s3c24x0/s3c24x0.h:35:
+typedef volatile u8	S3C24X0_REG8;
+typedef volatile u16	S3C24X0_REG16;
+typedef volatile u32	S3C24X0_REG32;

I'll fix these errors in another patch.

Tested by running MAKEALL for ARM8 targets and ensuring there were no new
errors or warnings.

eb0ae7f549 Clean-up of s3c24x0 drivers excluding nand driver
This patch re-formats the arm920t s3c24x0 driver files, excluding the nand
driver, in preparation for changes to add support for the Embest SBC2440-II Board.

The changes are as follows:
- re-indent the code using Lindent
- make sure register layouts are defined using a C struct
- replace the upper-case typedef'ed C struct names with lower case
  non-typedef'ed ones
- make sure registers are accessed using the proper accessor functions
- run checkpatch.pl and fix any error reports

It assumes the following patch has been applied first:
- [U-Boot][PATCH-ARM] CONFIG_SYS_HZ fix for ARM902T S3C24X0 Boards, 05/09/2009
- patches 1/4 and 2/4 of this series

Tested on an Embest SBC2440-II Board with local u-boot patches as I don't have
any s3c2400 or s3c2410 boards but need this patch applying before I can submit
patches for the SBC2440-II Board. Also, temporarily modified sbc2410x, smdk2400,
smdk2410 and trab configs to use the mtd nand driver (which isn't used by any
board at the moment), ran MAKEALL for all ARM9 targets and no new warnings or
errors were found.

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.

54e822f959 Replace __asm references with __asm__
__asm__ follows gcc's documented syntax and is generally more common
than __asm.  This change is only asthetic and should not affect
functionality.

53677ef18e Big white-space cleanup.
This commit gets rid of a huge amount of silly white-space issues.
Especially, all sequences of SPACEs followed by TAB characters get
removed (unless they appear in print statements).

Also remove all embedded "vim:" and "vi:" statements which hide
indentation problems.

* Add new meaning to "autostart" environment variable:
  If set to "no", a standalone image passed to the

  (and eventually uncompressed), but NOT be started.
  This can be used to load and uncompress arbitrary

  Cleanup & bug fixes for JFFS2 code:
  - the memory mangement was broken. It caused havoc on malloc by

  - the length calculation for files was wrong, sometimes resulting
    in short file reads.
  - data copying now optionally takes fragment version numbers into
    account, to avoid copying from older data.
  See doc/README.JFFS2 for details.
