* imx-common: consider mux_ctrl_ofs when setting mux_modePeng Fan2015-09-24-4/+3
| | | | | | | | | | | | | | | | | | | | Some i.MXes use __NA_ or 0 to avoid setting mux_mode, but the following patch only take i.MX6/7 into consideration. "c3c8a5748897b24f18618047804317167a531dd3 imx-common: fix iomux settings" Use is_soc_type(MXC_CPU_MX7) to avoid breaking other i.MXes when setting mux_mode. In this patch, switch to use "asm/imx-common/sys_proto.h" to avoid build break for "is_soc_type" for vf610 and mx25.

* imx-common: fix iomux settingsPeng Fan2015-09-20-2/+1
| | | | | | | | | | | | When setting iomux for a pin mux, there is no need to check mux_ctrl_ofs. Also If still checking mux_ctrl_ofs, we have no chance to set iomux for i.MX7D IOMUXC_LPSR_SW_MUX_CTL_PAD_GPIO1_IO00, because the mux_ctrl_ofs for this register is 0.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. Introduce a new structure `struct mxc_i2c_bus`, this structure will used for non-DM and DM. 2. Remove `struct mxc_i2c_regs` structure, but use register offset to access registers based on `base` entry of `struct mxc_i2c_bus`. 3. Remove most `#ifdef I2C_QUIRK_REG`. Using driver_data to contain platform flags. A new flag is introduced, I2C_QUIRK_FLAG. 4. Most functions use `struct mxc_i2c_bus` as one of the parameters. Make most functions common to DM and non-DM, try to avoid duplicated code. 5. Support DM, but pinctrl is not included. Pinmux setting is still set by setup_i2c, but we do not need bus_i2c_init for DM. 6. struct i2c_parms and struct sram_data are removed. 7. Remove bus_i2c_read bus_i2c_write prototype in header file. The frist paramter of bus_i2c_init is modified to i2c index. Add new prototype i2c_idle_bus and force_bus_idle. Since bus_i2c_init is not good for DM I2C and pinctrl is missed, we use a weak function for i2c_idle_bus. Board file take the responsibility to implement this function, like this: " int i2c_idle_bus(struct mxc_i2c_bus *i2c_bus) { if (i2c_bus->index == 0) force_bus_idle(i2c_pads_info0); else if (i2c_bus->index == 1) force_bus_idle(i2c_pads_info1); else xxxxxx } " 8. Introduce a weak function, enable_i2c_clk 9. Tested on an i.MX7 platform.

* imx6: Added DEK blob generator commandRaul Cardenas2015-03-02-0/+109
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Freescale's SEC block has built-in Data Encryption Key(DEK) Blob Protocol which provides a method for protecting a DEK for non-secure memory storage. SEC block protects data in a data structure called a Secret Key Blob, which provides both confidentiality and integrity protection. Every time the blob encapsulation is executed, a AES-256 key is randomly generated to encrypt the DEK. This key is encrypted with the OTP Secret key from SoC. The resulting blob consists of the encrypted AES-256 key, the encrypted DEK, and a 16-bit MAC. During decapsulation, the reverse process is performed to get back the original DEK. A caveat to the blob decapsulation process, is that the DEK is decrypted in secure-memory and can only be read by FSL SEC HW. The DEK is used to decrypt data during encrypted boot. Commands added -------------- dek_blob - encapsulating DEK as a cryptgraphic blob Commands Syntax --------------- dek_blob src dst len Encapsulate and create blob of a len-bits DEK at address src and store the result at address dst.

| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On mx6 sabreauto board, there are two USB ports: 0: OTG 1: HOST The EHCI driver is enabled for this board, but the IOMUX and VBUS power control is not implemented, which cause both USB port failed to work. This patch fix the problem by adding the board support codes. Since the power control uses the GPIO pin from port expander MAX7310, the PCA953X driver is enabled for accessing the MAX7310. The ID pin of OTG Port needs to configure the GPR1 bit 13 for selecting its daisy chain. Add a new function "imx_iomux_set_gpr_register" to handle GPR register setting.

Otherwise, the GPT will stay to use 32Khz OSC as clock source. In the implementation, since only the GPT on i.MX6 series provide the clock source option for 24Mhz OSC. For others (only i.MX5 and i.MX6 compile the driver), if the configuration is set, the perclk will be selected as clock source. MX6Q/D Rev 1.0 and MX6SL are special in the implementation, because they don't have the 24Mhz OSC clock source option, so also select the perclk for them. For MX6SL, we will set the OSC 24Mhz to perclk in CCM, so eventually the clock comes from OSC 24Mhz. Signed-off-by: Ye.Li <B37916@freescale.com>

| | | | | | | | | | | | | 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: Remove duplication of iomuxc structureFabio Estevam2014-07-23-2/+1
| | | | | | | | | | | | | | | There is no need to keep iomuxc_base_regs structure as it serves the exact same purpose of the iomuxc structure, which is to provide access to the GPR registers. The additional fields of iomuxc_base_regs are not used. Other advantage of 'iomuxc' is that it has a shorter name and the variable declarations can fit into a single line. So remove iomuxc_base_regs structure and use iomuxc instead. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Acked-by: Stefano Babic <sbabic@denx.de>
