x86: Fix some bugs in the i8402 driver when no controller is present

2011-11-29T10:31:35+00:00

If no controller is present, the i8402 driver should return immediately and
not attempt to operate on the missing hardware.

In kbd_input_empty, the status register is checked every millisecond to see
whether the input buffer is empty, up to a timeout which is tracked by
decrimenting a counter each time the check is performed. The decrement is
performed with a postfix -- operator, and the value of the counter is
checked in place. That means that when the counter reaches zero and the
loop terminates, it will actually be decrimented one more time and become
-1. That value is returned as the return value of the function. That would
give the right answer if it wasn't for that extra decrement because a
timeout would indicate that the buffer never became empty.

This change fixes both of those bugs.

Switch from archive libraries to partial linking

2010-11-17T20:02:18+00:00

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.

Remove HMI10 board support

2010-09-19T19:28:25+00:00

Recent changes caused that the HMI10 board now is included in the
boards built by MAKEALL, which revealed that compilation for this
board has been broken for a long time:

ps2ser.c: In function 'ps2ser_init':
ps2ser.c:155: error: 'UART_LCR' undeclared (first use in this function)
ps2ser.c:155: error: (Each undeclared identifier is reported only once
ps2ser.c:155: error: for each function it appears in.)
ps2ser.c:156: error: 'UART_DLL' undeclared (first use in this function)

ps2ser.c: In function 'ps2ser_interrupt':
ps2ser.c:293: error: 'UART_IIR' undeclared (first use in this function)

The board is orphaned, and AFAICT has reached EOL.
Drop support for it.

License cleanup: remove unintended "All Rights Reserved" notices.

2009-09-04T21:00:56+00:00

Some files included my old standerd file header which had a "All
Rights Reserved" part. As this has never been my intention, I remove
these lines to make the files compatible with GPL v.2 and later.

stdio/device: rework function naming convention

2009-07-17T22:27:46+00:00

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.

Rename common ns16550 constants with UART_ prefix to prevent conflicts

2009-04-03T20:34:07+00:00

Fix problems introduced in commit
7b5611cdd12ca0cc33f994f0d4a4454788fc3124 [inka4x0: Add hardware
diagnosis functions for inka4x0] which redefined MSR_RI which is
already used on PowerPC systems.

Also eliminate redundant definitions in ps2mult.h.  More cleanup will
be needed for other redundant occurrences though.
