* MX: serial_mxc: cleanup removing nasty #ifdefStefano Babic2011-12-06-0/+6
| | | | | | | | | | | | | | | | | | The serial driver for iMX SOCs is continuosly changed if a new SOC or not yet used port is used. CONFIG_SYS_<SOC>_<UART Port> defines were used only to find the base address for the selected UART. Instead of that, move the base address to the board configuration file and drop all #ifdef from driver.

* mx31: Use proper IO accessor for GPR registerFabio Estevam2011-11-11-1/+6
| | | | | | | Use proper IO accessor for GPR register. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Acked-by: Stefano Babic <sbabic@denx.de>
* mx31: add ESD control registersHelmut Raiger2011-11-03-0/+13
| | | | | | | | This allows to initialize DDR memory in C code. Currently all mx31 boards use assembler code (lowlevel_init.S) Signed-off-by: Helmut Raiger <helmut.raiger@hale.at> Acked-by: Stefano Babic <sbabic@denx.de>

* mx31: Introduce mx31_set_gpr functionFabio Estevam2011-11-03-0/+38
| | | | | | | | | | Introduce mx31_set_gpr function for setting the GPR (General Purpose Register) on MX31. This function can be useful for setting a group of pins into tied to some specific peripherals. Reuse this function from the linux kernel. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com>
* mx31: provide readable WEIM CS accessorHelmut Raiger2011-10-27-3/+32
| | | | | | | | | | | | 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/+14
| | | | | | | | | | | | 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>

* imx: Add support for USB EHCI on imx25Matthias Weisser2011-07-14-1/+1
| | | | | | | Adding support for USB host on imx25 using the internal PHY. Changing the name of base address define for imx31 to get some unification. Signed-off-by: Matthias Weisser <weisserm@arcor.de>
* MX31: change return value of get_cpu_revStefano Babic2011-05-11-1/+1
| | | | | | | | | | Drop warnings in get_cpu_rev and changes the return value (a u32 instead of char * is returned) of the function to be coherent with other processors. Signed-off-by: Stefano Babic <sbabic@denx.de> CC: Detlev Zundel <dzu@denx.de> CC: 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 Babic2011-04-27-0/+752
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.
