| * scripts: imx: support signing for i.MX8MQRouven Czerwinski2019-08-071-0/+2
| | | | | | | | | | | | | | | | | | | | Implement signing of the PBL for i.MX8MQ. The imagesize is also modified to i.MX8MQ to only contain the PBL. This obsoletes the max_load_size, which is kept for other boards currently using it.

| | | | | | | | | | | | | | | | | | Add a function to load and copy the piggy data to the correct offset expected by barebox in the RAM. This way the PBL can later verify the piggydata before uncompressing and loading the main barebox.

* | pinctrl: i.MX iomux-v1: Make base address initialization unnecessarySascha Hauer2019-08-141-1/+20
|/ | | | | | | | | | | | So far we have imx_gpio_mode() to configure a pinmux entry for the older i.MX pinmuxes. For this to work imx_iomuxv1_init() must be called beforehand to configure the base address. Simplify this by introducing SoC specific variants of imx_gpio_mode() which also pass the base address. This makes initialization of the base address unnecessary and the functions usable for PBL. Consequently also compile the code for PBL. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* ARM: i.MX8MQ: Don't use cpu_is_mx8mq() at core_initcall levelAndrey Smirnov2019-03-181-0/+1
| | | | | | | | | | | | | | | | | Since __imx_cpu_type won't be initialized until imx_init()@postcore_initcall is executed cpu_is_mx8mq() will only work correctly at core_initcall level so long as imx_cpu_type does not resolve into __imx_cpu_type. This is currently the case and imx8mq_init_syscnt_frequency() works as expected, but it probably won't be in the future. To avoid this problem introduce imx8mq_cpu_lowlevel_init() and do system counter frequency initialization there. Also convert all of the i.MX8MQ boards to use this new function.

* | scripts: imx-image: Add support for max_load_size optionSascha Hauer2018-11-301-0/+1
|/ | | | | | | | | | | | | When an image is loaded to SRAM we can normally only load a part of the full image, limited by the available space in SRAM. We currently load the pblb image which is the executable part of the PBL without the compressed barebox payload. We are going to link the compressed barebox image into the pbl image though, so we can't see the desired load size from outside the image anymore. This adds a max_load_size option to set this size explicitly. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * scripts: imx: Support encrypted boot with HABv4Marcin Niestroj2018-09-042-0/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | .imxcfg configuration files support few more commands, all starting with "hab_encrypt" string. That way it is possible to easily ignore these commands, when image encryption was not requested. Hence, we can use single .imxcfg file to generate signed and encrypted images in the same build. Images are encrypted in place by Freescale Code Signing Tool (cst), using Data Encryption Key (DEK). This key needs to be encapsulated by processor's hardware encryption engine to produce DEK blob, which is unique for each device. DEK blob needs to be part of CSF area, so we make enough space on the end of image to simply append it later, e.g. during device flash procedure. Introduced code was developed and tested on NXP i.MX6UL platform. Signed-off-by: Marcin Niestroj <m.niestroj@grinn-global.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* | scripts: imx: Add support for signed HDMI firmwareAndrey Smirnov2018-09-041-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Boot header on i.MX8MQ SoC allows embedding signed HDMI firmware images that are used by mask ROM code during the very early stages of boot. Since providing that firmware appear to be necessary to enable SoC's HDMI/DP functionality extend imx-image tool to support this feature. To do that add code implementing "signed_hdmi_firmware" keyword, which allows users to specify a path to a binary blob containing all of the necessary headers and footers as well firmware data and code sections (this is how such images are provieded by NXP) Signed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* | ARM: i.MX: Reset OTG controller during startupSascha Hauer2018-09-041-0/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When booting from USB it's sometimes observed that the USB stack on the remote host gets confused. This happens when we adjust the PLLs the USB controller is hanging on. The ROM just leaves the USB controller enabled when it passes control to the bootloader, so in case the usb clks are enabled make sure we reset the otg before doing any critical clock operations. This is currently done for i.MX50, i.MX51, i.MX53 and i.MX6, but a similar thing can happen on other i.MXes aswell.
