* ARM: i.MX: provide access to reset cause through get_imx_reset_cause()Eric Nelson2015-02-17-1/+9

* sata: fix reset_sata for dwc_ahsataSoeren Moch2014-12-01-0/+3
| | | | | | | | | | | - fix crash when sata device is not initialized - remove disable_sata_clock() since it is not clear which clock for which device should be disabled here - call disable_sata_clock() for mx6 in preboot_os instead Signed-off-by: Soeren Moch <smoch@web.de> Acked-by: Nikita Kiryanov <nikita@compulab.co.il> Tested-by: Nikita Kiryanov <nikita@compulab.co.il>
* arm: imx: stop sata on bootNikita Kiryanov2014-11-24-2/+6
| | | | | | | | | | | | | | Ideally, the Linux kernel should get the hardware in its most untouched state. For the most part, U-Boot does not reset the various subsystems it touches before boot, and usually Linux deals with it, but on some boards (cm_fx6) the Linux kernel fails to detect the ssd correctly if sata is used by U-Boot. Power off sata on OS boot so that Linux will have a clean state to work with. Signed-off-by: Nikita Kiryanov <nikita@compulab.co.il> Cc: Stefano Babic <sbabic@denx.de>
* mx6: thermal: Check cpu temperature via thermal sensorYe.Li2014-11-21-0/+21
| | | | | | | | Add imx6 thermal device to mx6 soc file. Read the cpu temperature using this device to access onchip thermal sensor. Signed-off-by: Ye.Li <B37916@freescale.com> Signed-off-by: Nitin Garg <nitin.garg@freescale.com>
* imx: consolidate set_chipselect_size functionFabio Estevam2014-11-20-0/+31
| | | | | | | | | | Move MX5 specific set_chipselect_size function into generic i.MX part, such that MX6 based boards are able to use this function as well. While doing this the iomuxc gpr member needed to be consolidated between MX5 and MX6. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com>

* ARM: mx6: Prevent overflow in DRAM size detectionMarek Vasut2014-08-20-0/+5
| | | | | | | | | | | | | The MX6 DRAM controller can be configured to handle 4GiB of DRAM, but only 3840 MiB of that can be really used. In case the controller is configured to operate a 4GiB module, the imx_ddr_size() function will correctly compute that there is 4GiB of DRAM in the system. Firstly, the return value is 32-bit, so the function will effectively return zero. Secondly, the MX6 cannot address the full 4GiB, but only 3840MiB of all that. Thus, clamp the returned size to 3840MiB in such case. Signed-off-by: Marek Vasut <marex@denx.de> Acked-by: Tim Harvey <tharvey@gateworks.com>
* mx6: Add support for the mx6solox variantFabio Estevam2014-07-10-0/+2
| | | | | | | | | | | | mx6solox is the newest member of the mx6 family. Some of the new features on this variants are: - Cortex M4 microcontroller (besides the CortexA9) - Dual Gigabit Ethernet Add the initial support for it. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com>
* imx: add comments and remove unused struct fieldsTim Harvey2014-06-06-9/+7
| | | | | | | | | | | | | | | | | Add comment block for the imx_ddr_size function and remove the extra unused fields from struct esd_mmdc_regs which are also not common between IMX53 and IMX6.

* mx6: Distinguish mx6dual from mx6quadFabio Estevam2014-02-11-0/+2
| | | | | | | | | | | | Currently when we boot a mx6dual U-boot reports that it is a mx6quad.

* imx-common: cpu: add imx_ddr_sizeTroy Kisky2012-11-10-0/+50
| | | | | | | | | | Read memory setup registers to determine size of available ram. This routine works for mx53/mx6x I need this because when mx6solo called get_ram_size with a too large maximum size, the system hanged. Signed-off-by: Troy Kisky <troy.kisky@boundarydevices.com>
* mx6: soc: update get_cpu_rev and get_imx_type for mx6solo/sololiteTroy Kisky2012-11-10-7/+9
| | | | | | | | | | Previously, the same value was returned for both mx6dl and mx6solo. Check number of processors to differeniate. Also, a freescale patch says that sololite has its cpu/rev stored at 0x280 instead of 0x260. I don't have a sololite to verify. Signed-off-by: Troy Kisky <troy.kisky@boundarydevices.com>

* MX: set a common place to share code for Freescale i.MXStefano Babic2012-09-10-0/+140
Up now only MX5 and MX6 can share code, because they have a common source directory in cpu/armv7. Other not armv7 i.MX can profit of the same shared code. Move these files into a directory accessible for all, similar to plat-mxc in linux. Signed-off-by: Stefano Babic <sbabic@denx.de>
