Phil Edworthy 99744b7e34 sh: Add SH7269 device and RSK2+SH7269 board
This is an sh2a device (max 266MHz) with FPU, video display
controller (VDC), 8 serial ports, 4 I2C channels, 3 CAN ports,
SD and on-chip USB.

The RSK2+SH7269 board uses the SH7269 processor. It is often
referred to as just rsk7269.

Vipin KUMAR f9da0f8943 Enable high speed support for USB device framework and usbtty
This patch adds the support for high speed in usb device framework and usbtty
driver. This feature has been kept within a macro CONFIG_USBD_HS, so the board
configuration files have to define this macro to enable high speed support.

Along with that specific peripheral drivers also need to define a function to
let the framework know that the enumeration has happened at high speed.
This function prototype is "int is_usbd_high_speed(void)"

Tom Rini b2fb47f187 USB: Use (get|put)_unaligned for accessing wMaxPacketSize
In 9792987721 Stefan describes a usecase
where the previous behavior of leaving wMaxPacketSize be unaligned
caused fatal problems.  The initial fix for this problem was incomplete
however as it showed another cases of non-aligned access that previously
worked implicitly.  This switches to making sure that all access of
wMaxPacketSize are done via (get|put)_unaligned.

In order to maintain a level of readability to the code in some cases
we now use a variable for the value of wMaxPacketSize and in others, a
macro.

Simon Glass efb2172ece Move timestamp and version files into 'generated' subdir
There is a rather subtle build problem where the build time stamp is not
updated for out-of-tree builds if there exists an in-tree build which
has a valid timestamp file. So if you do an in-tree build, then an
out-of-tree build your timestamp will not change.

The correct timestamp_autogenerated.h lives in the object tree, but it
is not always found there. The source still lives in the source tree and
when compiling version.h, it includes timestamp_autogenerated.h. Since
the current directory is always searched first, this will come from the
source tree rather than the object tree if it exists there. This affects
dependency generation also, which means that common/cmd_version.o will not
even be rebuilt if you have ever done an in-tree build.

A similar problem exists with the version file.

This change moves both files into the 'generated' subdir, which is already
used for asm-offsets.h. Then timestamp.h and version.h are updated to
include the files from there.

There are other places where these generated files are included, but I
cannot see why these don't just use the timestamp.h and version.h headers.
So this change also tidies that up.

I have tested this with in- and out-of-tree builds, but not SPL. I have
looked at various other options for fixing this, including sed on the dep
files, -I- and -include flags to gcc, but I don't think they can be made
to work. Comments welcome.

Sebastien Carlier 6d8962e814 Switch from archive libraries to partial linking
Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils.  As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".

This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.

The name of each former library archive is preserved except for
extensions which change from ".a" to ".o".  This commit updates
references accordingly where needed, in particular in some linker
scripts.

This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols.  Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.

Stefan Roese 1a2d9b30e3 ns16550: Add WATCHDOG_RESET to putc for short watchdog timeout boards
Call watchdog_reset() upon newline. This is done here in putc
since the environment code uses a single puts() to print the complete
envrironment upon "printenv". So we can't put this watchdog call
in puts().

This is needed for boards with a very short watchdog timeout, like the
lwmon5 with a 100ms timeout. Without this patch this board resets in the
commands with long outputs, like "printenv" or "fdt print".

Note that the image size is not increased with this patch when
CONFIG_HW_WATCHDOG or CONFIG_WATCHDOG are not defined since the compiler
optimizes this additional code away.

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:

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

kevin.morfitt@fearnside-systems.co.uk 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.

Jean-Christophe PLAGNIOL-VILLARD 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.
