2015-04-23ARM: vf610: Move DDR3 initialization to imx-commonSanchayan Maity
In order to avoid code duplication, move the DDR3 initialization to the common place under imx-common. Currently ROW_DIFF and COL_DIFF can be chosen from the board file. The JEDEC timings are specified using a common ddr3_jedec_timings structure. Signed-off-by: Stefan Agner <stefan@agner.ch> Signed-off-by: Sanchayan Maity <maitysanchayan@gmail.com>
2015-03-23ARM: iMX: define an IMX_CONFIG Kconfig optionBoris BREZILLON
IMX_CONFIG is currently passed via the SYS_EXTRA_OPTIONS which is marked as deprecated. Add a new Kconfig file under arch/arm/imx-common and define the IMX_CONFIG Kconfig in there. Each board is supposed to provide a default value pointing to the appropriate imximage.cfg file. Signed-off-by: Boris Brezillon <boris.brezillon@free-electrons.com>
2015-03-02imx6: Added DEK blob generator commandRaul Cardenas
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.

2014-11-24arm: imx: stop sata on bootNikita Kiryanov
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>

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.

2014-11-03imx: mx6 sabreauto: Add board support for USB EHCIYe.Li
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.

2014-11-03imx: gpt: Add High frequency clock source support for GPTYe.Li
Introduce a new configuration "CONFIG_MXC_GPT_HCLK". When it is set, the GPT will select a high frequency clock as clock source. 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>

2014-08-20ARM: mx6: Prevent overflow in DRAM size detectionMarek Vasut
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>
2014-07-23mx6: Remove duplication of iomuxc structureFabio Estevam
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.

2014-02-19kbuild: use Linux Kernel build scriptsMasahiro Yamada
Now we are ready to switch over to real Kbuild. This commit disables temporary scripts: scripts/{Makefile.build.tmp, Makefile.host.tmp} and enables real Kbuild scripts: scripts/{Makefile.build,Makefile.host,Makefile.lib}. This switch is triggered by the line in scripts/Kbuild.include -build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build.tmp obj +build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build obj We need to adjust some build scripts for U-Boot. But smaller amount of modification is preferable. Additionally, we need to fix compiler flags which are locally added or removed. In Kbuild, it is not allowed to change CFLAGS locally. Instead, ccflags-y, asflags-y, cppflags-y, CFLAGS_$(basetarget).o, CFLAGS_REMOVE_$(basetarget).o are prepared for that purpose.
