2009-04-01rtc: remove broken rtc_read and rtc_write declarationsKim Phillips
commit 04e11cf3 "rtc: add support for 4543 RTC (manufactured by e.g. EPSON)" introduces the following build error on boards configuring e.g, the ds1374 rtc: Configuring for MPC837XEMDS board... ds1374.c:103: error: static declaration of 'rtc_read' follows non-static declaration /home/r1aaha/git/u-boot/include/rtc.h:64: error: previous declaration of 'rtc_read' was here ds1374.c:104: error: conflicting types for 'rtc_write' /home/r1aaha/git/u-boot/include/rtc.h:65: error: previous declaration of 'rtc_write' was here this reverts the erroneous chunk.

2008-05-21Big white-space cleanup.Wolfgang Denk
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>
2008-03-20LWMON5: POST RTC fixYuri Tikhonov
Modify the RTC API to provide one a status for the time reported by the rtc_get() function: 0 - a reliable time is guaranteed, < 0 - a reliable time isn't guaranteed (power fault, clock issues, and so on). The RTC chip drivers are responsible for providing this info if the corresponding chip supports such functionality. If not - always report that the time is reliable. The POST RTC test was modified to detect the RTC faults utilizing this new rtc_get() feature. Signed-off-by: Yuri Tikhonov <yur@emcraft.com>
