* usb: ehci-mx6: Rename the USB register base addressYe.Li2014-09-29-7/+2
| | | | | | | | | | | | The mx6sl/mx6sx has 2 OTG and 1 host. So they have name "USBO2H_USB_BASE_ADDR" in imx-regs.h. The driver hard codes the USB base address name to "USBOH3", which causes the driver failed to build for mx6sl/mx6sx. This patch uniform the address name to "USB_BASE_ADDR" for all mx6 series.

* imx: Support i.MX6 High Assurance Boot authenticationNitin Garg2014-09-22-1/+211
| | | | | | | | | | | | When CONFIG_SECURE_BOOT is enabled, the signed images like kernel and dtb can be authenticated using iMX6 CAAM. The added command hab_auth_img can be used for HAB authentication of images. The command takes the image DDR location, IVT (Image Vector Table) offset inside image as parameters. Detailed info about signing images can be found in Freescale AppNote AN4581. Signed-off-by: Nitin Garg <nitin.garg@freescale.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch implements a workaround to fix DDR3 memory issue. The code for workaround detects PGSR0 errors and then preps for and executes a software-controlled hard reset.In board_early_init, where logic has been added to identify whether or not the previous reset was a PORz. PLL initialization is skipped in the case of a software-controlled hard reset.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At the high level, the problem is that we set gd multiple times (and still do, even after the commit we're reverting). We set important parts of gd to the copy which is not above stack but rather in the data section. For the release, we're going to revert this change and for the next release we shall correct things to only, really, set gd once to an appropriate location and ensure that comments about it are correct too.

It has been tested on trimslice and also using the new iotrace feature. The implementation uses a top-level GPIO device (which has no actual GPIOS). Under this all the banks are created as separate GPIO devices. The GPIOs are named as per the Tegra datasheet/header files: A0..A7, B0..B7, ..., Z0..Z7, AA0..AA7, etc. Since driver model is not yet available before relocation, or in SPL, a special function is provided for seaboard's SPL code.

| * | | arm: Fix _start for CONFIG_SYS_DV_NOR_BOOT_CFGBenoît Thébaudeau2014-09-11-1/+2

Because of that, if by lack of luck 'gd->mon_len = (ulong)&__bss_end - (ulong)_start' (see setup_mon_len()) was a multiple of 4 kiB (see reserve_uboot()), then the last BSS word overlapped the first word of the following reserved RAM area (or went beyond the top of RAM without such an area) after relocation because __image_copy_start did not match _start (see relocate_code()). This was broken by commit 41623c9 'arm: move exception handling out of start.S files', which defined _start twice (before and after the CONFIG_SYS_DV_NOR_BOOT_CFG word), then by commit 0a26e1d 'arm: fix a double-definition error of _start symbol', which kept the definition of the _start symbol after the CONFIG_SYS_DV_NOR_BOOT_CFG word. This new commit fixes this issue by restoring the original behavior, i.e. by defining the _start symbol before the CONFIG_SYS_DV_NOR_BOOT_CFG word.

| * | | arm: Make reset position-independentBenoît Thébaudeau2014-09-11-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some boards, like mx31pdk and tx25, require the beginning of the SPL code to be position-independent. For these two boards, this is because they use the i.MX external NAND boot, which starts by executing the first NAND Flash page from the NFC page buffer. The SPL then needs to copy itself to its actual link address in order to free the NFC page buffer and use it to load the non-SPL image from Flash before running it. This means that the SPL runtime address differs from its link address between the reset and the initial copy performed by board_init_f(), so this part of the SPL binary must be position-independent. This requirement was broken by commit 41623c9 'arm: move exception handling out of start.S files', which used an absolute address to branch to the reset routine. This new commit restores the original behavior, which just performed a relative branch. This fixes the boot of mx31pdk and tx25.

* | | arm: mx6: ddr: fix cs0_end calculationNikita Kiryanov2014-09-09-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current way of calculation CS0_END field for MMDCx_MDASP register is problematic because in most cases the user is forced to define cs_density in an unnatural way: as value - 2, instead of value. This breaks the abstraction provided by struct mx6_ddr_sysinfo because the user is forced to be aware of the way the calculation is performed. Refactor the calculation.

* | | arm: mx6: ddr: configure MMDC for slow_pdNikita Kiryanov2014-09-09-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to MX6 TRM, both MMDC and DRAM should be configured to the same powerdown precharge. Currently, mx6_dram_cfg() configures MMDC for fast pd (MDPDC[7] = 0), and the DRAM for 'slow exit (DLL off)' (MR0[12] = 0). Configure MMDC for slow pd.
