* x86: Fix some bugs in the i8402 driver when no controller is presentGabe Black2011-11-29-1/+11
| | | | | | | | | | | | | | | | | | | 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 linkingSebastien Carlier2010-11-17-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: Sebastien Carlier <sebastien.carlier@gmail.com>
* Remove HMI10 board supportWolfgang Denk2010-09-19-92/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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:157: error: 'UART_DLM' undeclared (first use in this function) ps2ser.c:159: error: 'UART_IER' undeclared (first use in this function) ps2ser.c:160: error: 'UART_MCR' undeclared (first use in this function) ps2ser.c:161: error: 'UART_FCR' undeclared (first use in this function) ps2ser.c:162: error: 'UART_FCR_ENABLE_FIFO' undeclared (first use in this function) ps2ser.c:166: error: 'UART_LSR' undeclared (first use in this function) ps2ser.c: In function 'ps2ser_putc': ps2ser.c:198: error: 'UART_LSR' undeclared (first use in this function) ps2ser.c:200: error: 'UART_TX' undeclared (first use in this function) ps2ser.c: In function 'ps2ser_getc_hw': ps2ser.c:224: error: 'UART_LSR' undeclared (first use in this function) ps2ser.c:225: error: 'UART_RX' 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. Signed-off-by: Wolfgang Denk <wd@denx.de>

* stdio/device: rework function naming conventionJean-Christophe PLAGNIOL-VILLARD2009-07-18-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 conflictsDetlev Zundel2009-04-03-10/+12
| | | | | | | | | | | | 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. Signed-off-by: Detlev Zundel <dzu@denx.de>

* Big white-space cleanup.Wolfgang Denk2008-05-21-9/+9
| | | | | | | | | | | 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. Signed-off-by: Wolfgang Denk <wd@denx.de>
