* Generic udelay() with watchdog supportIngo van Lil2009-12-05-1/+1
| | | | | | | | | | | | | According to the PPC reference implementation the udelay() function is responsible for resetting the watchdog timer as frequently as needed. Most other architectures do not meet that requirement, so long-running operations might result in a watchdog reset. This patch adds a generic udelay() function which takes care of resetting the watchdog before calling an architecture-specific __udelay(). Signed-off-by: Ingo van Lil <inguin@gmx.de>

* arm: timer and interrupt init reworkJean-Christophe PLAGNIOL-VILLARD2009-06-12-3/+3
| | | | | | | | | | | | | | actually the timer init use the interrupt_init as init callback which make the interrupt and timer implementation difficult to follow so now rename it as int timer_init(void) and use interrupt_init for interrupt btw also remane the corresponding file to the functionnality implemented as ixp arch implement two timer - one based on interrupt - so all the timer related code is moved to timer.c Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com>

* i.MX31: switch to CFG_HZ=1000Guennadi Liakhovetski2008-10-08-29/+50
| | | | | | | | | | Switch to the standard CFG_HZ=1000 value, while at it, minor white-space cleanup, remove CFG_CLKS_IN_HZ from config-headers. Tested on mx31ads, provides 2% or 0.4% precision depending on the CONFIG_MX31_TIMER_HIGH_PRECISION flag. Measured with stop-watch on 100s boot-delay. Signed-off-by: Guennadi Liakhovetski <lg@denx.de>
* i.MX31: Add reset_timer() and modify get_timer_masked().Magnus Lilja2008-09-12-4/+20
| | | | | | | | This patch adds the reset_timer() function (needed by nand_base.c) and modifies the get_timer_masked() to work in the same way as the omap24xx function. Signed-off-by: Magnus Lilja <lilja.magnus@gmail.com>
* MX31: fix bit masks in function mx31_decode_pll()Jens Gehrlein2008-08-25-2/+2
| | | | | | Bits MPCTL[MFN] and MPCTL[MFD] were not fully covered. Signed-off-by: Jens Gehrlein <sew_s@tqs.de>
* i.MX31: Fix mx31_gpio_mux() function and MUX_-macros.Magnus Lilja2008-08-11-2/+2
| | | | | | | | | | Correct the mx31_gpio_mux() function to allow changing all i.MX31 IOMUX contacts instead of only the first 256 ones as is the case prior to this patch. Add missing MUX_* macros and update board files to use the new macros. Signed-off-by: Magnus Lilja <lilja.magnus@gmail.com>
* i.MX31: fixed CTRL-C detectionJuergen Kilb2008-07-01-1/+2
| | | | | | | | | | The Register URXD contains status information in bits [15..8]. With status bit 15 set, CTRL-C was reported as 0x8003 instead of 0x03. Therefore CTRL-C was not detected. To solve this, bits [15..8] were masked out now. Signed-off-by: Juergen Kilb <J.Kilb@gmx.de> Acked-by: Felix Radensky <felix@embedded-sol.com>
* Big white-space cleanup.Wolfgang Denk2008-05-21-35/+35
| | | | | | | | | | | 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>
* mx31ads: fix 32kHz clock handlingGuennadi Liakhovetski2008-05-10-2/+2
| | | | | | | | | According to schematics and to RedBoot sources, the MX31ADS uses a 32768Hz oscillator as a SKIL source. Fix previously wrongly assumed 32000Hz value. Also fix a typo when verifying a jumper configuration. While at it, make two needlessly global functions static. Signed-off-by: Guennadi Liakhovetski <lg@denx.de>

* Revert merge of git://www.denx.de/git/u-boot-arm, commit 62479b18:Wolfgang Denk2008-04-11-486/+0
| | | | | | | | | | | | | | | | | | | | | | Reverting became necessary after it turned out that the patches in the u-boot-arm repo were modified, and in some cases corrupted. This reverts the following commits: 066bebd6353e33af3adefc3404560871699e9961 7a837b7310166ae8fc8b8d66d7ef01b60a80f9d6 c88ae20580b2b01487b4cdcc8b2a113f551aee36 a147e56f03871bba4f05058d5e04ce7deb010b04 d6674e0e2a6a1f033945f78838566210d3f28c95 8c8463cce44d849e37744749b32d38e1dfb12e50 c98b47ad24b2d91f41c09a3d62d7f70ad84f4b7d 8bf69d81782619187933a605f1a95ee1d069478d 8c16cb0d3b971f46fbe77c072664c0f2dcd4471d a574a73852a527779234e73e17e7597fd8128882 1377b5583a48021d983e1fd565f7d40c89e84d63 1704dc20917b4f71e373e2c888497ee666d40380 Signed-off-by: Wolfgang Denk <wd@denx.de>
