2015-08-02imx: mx6ul update soc related settingsPeng Fan
1.Update WDOG settings. 2.No need to gate/ungate all PFDs for i.MX6UL. Signed-off-by: Peng Fan <Peng.Fan@freescale.com> Signed-off-by: Ye.Li <B37916@freescale.com>
2015-08-02imx: mx6ul select SYS_L2CACHE_OFFPeng Fan
i.MX6UL features an Cortex-A7 core, it does not have PL310 as other i.MX6 chips. To Cortex-A7 core, If D-Cache is enabled, L2 Cache is enabled. There is on specific switch for on/off L2 Cache, so default select SYS_L2CACHE_OFF. Signed-off-by: Peng Fan <Peng.Fan@freescale.com>
2015-08-02imx:mx6ul add clock supportPeng Fan
1. Add enet, uart, i2c, ipg clock support for i.MX6UL. 2. Correct get_periph_clk, it should account for MXC_CCM_CBCDR_PERIPH_CLK2_PODF_MASK. 3. Refactor get_mmdc_ch0_clk to make all i.MX6 share one function, but not use 'ifdef'. 4. Use CONFIG_FSL_QSPI for enable_qspi_clk, but not #ifdef CONFIG_MX6SX. 5. Use CONFIG_PCIE_IMX for pcie clock settings, use CONFIG_CMD_SATA for sata clock settings. In this way, we not need "#if defined(CONFIG_MX6Q) || defined....", only need one CONFIG_PCIE_IMX in header file.

Add I2C4 clock support for i.MX6SX. Since we use runtime check, but not macro, we need to remove `#ifdef ..` in crm_regs.h, or gcc will fail to compile the code succesfully.

Return this value as well as min/max temperature based on the value. Note that the IMX6SDLRM and the IMX6SXRM do not indicate this in the their Fusemap Description Table however Freescale has confirmed that these eFUSE bits match the description within the IMX6DQRM and that they will be added to the next revision of the respective reference manuals.

Return this frequency so that it can be used elsewhere. Note that the IMX6SDLRM and the IMX6SXRM do not indicate this in the their Fusemap Description Table however Freescale has confirmed that these eFUSE bits match the description within the IMX6DQRM and that they will be added to the next revision of the respective reference manuals.

2015-05-19arm: mx6: ddr: set fast-exit on DDR3 if pd_fast_exit specifiedTim Harvey
Commit fa8b7d66f49f0c7bd41467fe78f6488d8af6976a introduced fast-exit support to the MMDC however enabling it on the DDR3 got missed. Make sure we enable it on the DDR3 as well. Gateworks uses Micron memory as well as Winbond in MX6. We have found in testing that we need to enable fast-exit for Winbond stability. Gateworks boards are currently the only boards using the MX6 SPL and enabling fast-exit mode. Signed-off-by: Tim Harvey <tharvey@gateworks.com>

2015-05-15mx6: Set shared override bit in PL310 AUX_CTRL registerFabio Estevam
Having bit 22 cleared in the PL310 Auxiliary Control register (shared attribute override enable) has the side effect of transforming Normal Shared Non-cacheable reads into Cacheable no-allocate reads. Coherent DMA buffers in Linux always have a Cacheable alias via the kernel linear mapping and the processor can speculatively load cache lines into the PL310 controller. With bit 22 cleared, Non-cacheable reads would unexpectedly hit such cache lines leading to buffer corruption. This was inspired by a patch from Catalin Marinas [1] and also from recent discussions in the linux-arm-kernel list [2] where Russell King and Rob Herring suggested that bootloaders should initialize the cache.

2015-05-15arm: mx6: Clamp MMDC and DDR3 clocks for timing calculationsNikolay Dimitrov
This is proposal for clamping the MMDC/DDR3 clocks to the maximum supported frequencies as per imx6 SOC models, and for dynamically calculating valid clock value based on mem_speed. Currently the code uses impossible values for mem_speed (1333, 1600 MT/s) for calculating the DDR timings, and uses fixed clock (528 or 400 MHz) which doesn't take into account DDR3 memory limitations.

2015-04-22arm: mx6: ddr: add pd_fast_exit flag to system informationTim Harvey
DDR3 has a special Precharge power-down mode: fast-exit vs slow-exit. In slow-exit mode the DLL is off but in some quiescent state that makes it easy to turn on again in tXPDLL cycles (about 10tCK) vs the full tDLLK (512tCK). In fast-exist mode the DLL is maintained such that it is ready again in about 3tCK. Signed-off-by: Tim Harvey <tharvey@gateworks.com>

2015-03-23ARM: mx6: move to a standard arch/board approachBoris BREZILLON
Freescale boards are currently all defined in arch/arm/Kconfig, which makes them hard to detect. Moreover the MX6 SoC variant (Q, D, DL, S, SL) selection is currently done via the SYS_EXTRA_OPTIONS option which marked as deprecated. Move to a more standard way to select sub-architecture and board by creating a Kconfig under arch/arm/cpu/armv7/mx6 and a new ARCH_MX6 option. Existing MX6 board definitions should be moved in this new Kconfig in choice menu, and new boards should be directly declared in this menu.

2014-11-12arm: imx: make bmode command work with SPL/U-Boot comboNikita Kiryanov
The bmode command forces the SoC to use a specific boot device by writing its boot mode into SRC_GPR9, and notifying the SoC of the change using SRC_GPR10[28] bit: if the bit is on, bootROM uses the value in SRC_GPR9 instead of SRC_SMBR1 to determine the boot device. SPL on the other hand is oblivious to this distinction, so once the bootROM loads SPL from the device configured in SRC_GPR10, SPL will attempt to load U-Boot from the device configured in SRC_SMBR1, which is not updated by the bootROM to the value in SRC_GPR9. The result is that the selected boot device is not used across all the boot stages. Update spl_boot_device() to look at gpr9 when necessary.
