2018-01-14arm: imx: hab: Only call ROM once headers are verifiedBryan O'Donoghue
Previous patches added IVT header verification steps. We shouldn't call hab_rvt_entry() until we have done the basic header verification steps. This patch changes the time we make the hab_rvt_entry() call so that it only takes place if we are happy with the IVT header sanity checks.

The IVT is a self-describing structure which contains a self field. The self field is the absolute physical base address the IVT ought to be at in memory.

2018-01-14arm: imx: hab: Add IVT header definitionsBryan O'Donoghue
The various i.MX BootROMs containing the High Assurance Boot (HAB) block rely on a data structure called the Image Vector Table (IVT) to describe to the BootROM where to locate various data-structures used by HAB during authentication. This patch adds a definition of the IVT header for use in later patches, where we will break the current incorrect dependence on fixed offsets in favour of an IVT described parsing of incoming binaries.

2018-01-14arm: imx: hab: Fix authenticate_image input parametersBryan O'Donoghue
u-boot command "hab_auth_img" tells a user that it takes - addr - image hex address - offset - hex offset of IVT in the image but in fact the callback hab_auth_img makes to authenticate_image treats the second 'offset' parameter as an image length. Furthermore existing code requires the IVT header to be appended to the end of the image which is not actually a requirement of HABv4. This patch fixes this situation by 1: Adding a new parameter to hab_auth_img - addr : image hex address - length : total length of the image - offset : offset of IVT from addr 2: Updates the existing call into authenticate_image() in arch/arm/mach-imx/spl.c:jump_to_image_no_args() to pass addr, length and IVT offset respectively. This allows then hab_auth_img to actually operate the way it was specified in the help text and should still allow existing code to work. It has the added advantage that the IVT header doesn't have to be appended to an image given to HAB - it can be prepended for example. Note prepending the IVT is what u-boot will do when making an IVT for the BootROM. It should be possible for u-boot properly authenticate images made by mkimage via HAB. This patch is the first step in making that happen subsequent patches will focus on removing hard-coded offsets to the IVT, which again is not mandated to live at the end of a .imx image.

2018-01-14arm: imx: hab: Fix authenticate_image result codeBryan O'Donoghue
authenticate_image returns 1 for success and 0 for failure. That result code is mapped directly to the result code for the command line function hab_auth_img - which means when hab_auth_img succeeds it is returning CMD_RET_FAILURE (1) instead of CMD_RET_SUCCESS (0). This patch fixes this behaviour by making authenticate_image() return 0 for success and 1 for failure. Both users of authenticate_image() as a result have some minimal churn. The upshot is once done when hab_auth_img is called from the command line we set $? in the standard way for scripting functions to act on.

2018-01-14arm: imx: hab: Make authenticate_image return intBryan O'Donoghue
Both usages of authenticate_image treat the result code as a simple binary. The command line usage of authenticate_image directly returns the result code of authenticate_image as a success/failure code. Right now when calling hab_auth_img and test the result code in a shell a passing hab_auth_img will appear to the shell as a fail. The first step in fixing this behaviour is to fix-up the result code return by authenticate_image() itself, subsequent patches fix the interpretation of authenticate_image so that zero will return CMD_RET_SUCCESS and non-zero will return CMD_RET_FAILURE. The first step is fixing the return type in authenticate_image() so do that now.

2018-01-12ARM: imx: cm_fx6: env: try to determine dtb to useChristopher Spinrath
Some distributions like Fedora expect U-Boot to select a proper devicetree. Since there are several variants of the cm-fx6 module featuring different SoC variants and the module can be paired with several baseboards, it is not viable to hardcode a filename. Instead, follow the lead of other i.MX6 based devices and try to determine the devicetree to use with the help of the board name and the SoC variant exported by the board code, before calling the distro bootcommand. For now, only for the Utilite Pro a proper devicetree filename is known but further variants of the Utilite Computer or other devices based on the cm-fx6 module may be added in the future.

2018-01-12ARM: imx: cm_fx6: export board and soc info to envChristopher Spinrath
Like many other i.MX6 based boards, there are multiple variants of the cm-fx6 module featuring different SoC variants. Furthermore, the module can be paired with multiple baseboards. At the same time modern distribution like Fedora require U-Boot to select a proper devicetree which depends on the SoC variant and the baseboard. Thus, export the SoC variant and the actual board to the environment following the conventions of other i.MX6 devices (e.g. the NXP boards) such that the environment can select a devicetree file to load. For now, we only know for sure that the cm-fx6 module and the SB-fx6m baseboard amount to a Utilite Computer variant (depending on the SoC). Further combinations may be added in the future; e.g. CompuLab's evaluation board once someone can verify the identification string stored in its eeprom.
