* mx31: provide readable WEIM CS accessorHelmut Raiger2011-10-27-3/+67
| | | | | | | | | | | | setup_weimcs() and some macros are added to support the setup for i.MX31 WEIM chip selects. As a compromise between verbosity and readability an ASCII-art'ish bit comment is used instead of bitfields. All i.MX31 boards have been patched to use this approach using a helper program to verify the changes. Signed-off-by: Helmut Raiger <helmut.raiger@hale.at> Acked-by: Stefano Babic <sbabic@denx.de>
* mx31: make HSP clock for mx3fb driver availableHelmut Raiger2011-10-13-0/+15
| | | | | | | | | | | | This additionally updates mx31/generic.c by - replacing __REG() macro accesses with readl() and writel() - providing macros for PDR0 and PLL bit accesses Signed-off-by: Helmut Raiger <helmut.raiger@hale.at> Acked-by: Marek Vasut <marek.vasut@gmail.com> Cc: Stefano Babic <sbabic@denx.de> Acked-by: Stefano Babic <sbabic@denx.de> Signed-off-by: Anatolij Gustschin <agust@denx.de>
* MX31: Disable watchdog during low-power modesFabio Estevam2011-09-30-0/+2
| | | | | | | | | | | Turn on the watchdog WDZST bit so that watchdog timer does not count during low power modes. Prior to applying this patch mx31pdk board got watchdog resets because when it booted in the Linux prompt and there was no activity, the system entered into idle mode while watchdog timer was still active. Fix this by disabling watchdog timer during idle mode. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com>

* ARM: MX31: Fix file name labelFabio Estevam2011-04-27-3/+3
| | | | | | | | | Commit 5d2c154 (IMX: MX31: Cleanup include files and drop nasty #ifdef in drivers) renamed mx31-imx-regs.h to imx-regs.h. Change the file label accordingly. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com>
* ARM: mx31: Print the silicon versionFabio Estevam2011-04-27-0/+25
| | | | | | | | | | | Use the same method of the Linux kernel to print the MX31 silicon version on boot. Tested on a MX31PDK with a 2.0 silicon, where it shows: CPU: Freescale i.MX31 rev 2.0 at 531 MHz Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com>
* IMX: MX31: Cleanup include files and drop nasty #ifdef in driversStefano Babic2011-04-27-3/+3
| | | | | | | | | | As exception among the i.MX processors, the i.MX31 has headers without general names (mx31-regs.h, mx31.h instead of imx-regs.h and clock.h). This requires several nasty #ifdef in the drivers to include the correct header. The patch cleans up the driver and renames the header files as for the other i.MX processors.

* MX31: add support for MX31 watchdogStefano Babic2011-04-27-0/+10
| | | | | | | | | | | | | | | | | | The patch add CONFIG_HW_WATCHDOG to be used with the internal watchdog timer of the MX31 processor. Two function are exported for the board maintainers: mxc_hw_watchdog_enable mxc_hw_watchdog_reset The board maintainer can decide to use mxc_hw_watchdog_reset as hw_watchdog_reset, or to implement his own function to reset the watchdog. The watchdog timer can be configured with CONFIG_SYS_WD_TIMER_SECS (value in seconds). The MX31 allows values between 0.5 (CONFIG_SYS_WD_TIMER_SECS = 0) and 128 seconds.

* Move architecture-specific includes to arch/$ARCH/include/asmPeter Tyser2010-04-13-0/+351
This helps to clean up the include/ directory so that it only contains non-architecture-specific headers and also matches Linux's directory layout which many U-Boot developers are already familiar with. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
