2017-07-12imx: reorganize IMX code as other SOCsStefano Babic
Change is consistent with other SOCs and it is in preparation for adding SOMs. SOC's related files are moved from cpu/ to mach-imx/<SOC>. This change is also coherent with the structure in kernel.

For i.MX6, the bootmode determine code is part of spl_boot_device, but there is might be a possibility for other part the code need to check the desired boot mode for adding new functionalities like modeboot env variable, or changing boot order etc. So introduced imx6_src_get_boot_mode which actually reading the boot mode register for desired modes. More cleanup will be add in future patches.

2017-01-27imx_common: check for bmode Serial DownloaderStefan Agner
Before commit 81c4eccb55cc ("imx: mx6: fix USB bmode to use reserved value") a non-reserved value has been used to trigger Serial Downloader using bmode, which translated to a GPR9 value of 0x10. However, on some boards the non-reserved value lead to unreliable bmode command. With the above mentioned commit, U-boot switched to use [7:4] b0001, which translates to GPR9 0x10 for Serial Downloader mode. Check for the new value and classify it as Serial Downloader mode.

2017-01-02arm: imx: add HAB authentication of image to SPL bootSven Ebenfeld
When using HAB as secure boot mechanism on Wandboard, the chain of trust breaks immediately after the SPL. As this is not checking the authenticity of the loaded image before jumping to it. The HAB status output will not be implemented in SPL as it adds a lot of strings that are only required in debug cases. With those it exceeds the maximum size of the available OCRAM (69 KiB). The SPL MISC driver support must be enabled, so that the driver can use OTP fuse to check if HAB is enabled.

2016-06-26common: Pass the boot device into spl_boot_mode()Marek Vasut
The SPL code already knows which boot device it calls the spl_boot_mode() on, so pass that information into the function. This allows the code of spl_boot_mode() avoid invoking spl_boot_device() again, but it also lets board_boot_order() correctly alter the behavior of the boot process. The later one is important, since in certain cases, it is desired that spl_boot_device() return value be overriden using board_boot_order().

2016-01-03imx_common: check for Serial Downloader in spl_boot_deviceStefano Babic
Check for bmode before reading the boot device to check if a serial downloader is started, and returns UART if the serial downloader is set, letting SPL to wait for an image if CONFIG_SPL_YMODEM_SUPPORT is set. This allows to load again a SPL based board with imx_usb_loader together with a tool such as kermit.

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.
