arm: imx: hab: Fix authenticate_image input parameters

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.

ARM: imx: cm_fx6: export board and soc info to env

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.

Tuomas Tynkkynen [Fri, 22 Dec 2017 22:30:56 +0000 (00:30 +0200)]
ARM: sunxi: Remove left-over cd-inverted property from pcDuino3

Commit 8620f384098b ("dm: sunxi: Linksprite_pcDuino3: Correct polarity
of MMC card detect") claims that the Pcduino3 device tree had an
incorrect polarity for the card detect pin and thus changed the polarity
flag of the cd-gpios from GPIO_ACTIVE_HIGH to GPIO_ACTIVE_LOW.

Actually the DT was correct since according to the mmc binding, a
combination of GPIO_ACTIVE_HIGH + cd-inverted results in an active-low
polarity. But because the U-Boot driver lacks the code to look at the
cd-inverted property (unlike the Linux driver) it interpreted the
polarity of active-high. Thus, after that commit the DT is actually
wrong from the binding/Linux point of view.

To make both Linux and U-Boot interpret the DT in the same way, just
drop the left-over cd-inverted property. I've sent a Linux patch to
switch all sunxi DTs over to not using the cd-inverted property, so
eventually all sunxi boards in U-Boot will be consistent in not using
cd-inverted.

6 years agosunxi: Add support for Libre Computer Board ALL-H3-CC H3 ver.
Chen-Yu Tsai [Thu, 7 Dec 2017 13:00:45 +0000 (21:00 +0800)]
sunxi: Add support for Libre Computer Board ALL-H3-CC H3 ver.

The Libre Computer Board ALL-H3-CC from Libre Technology is a Raspberry
Pi B+ form factor single board computer based on the Allwinner H3 SoC.
The board has 1GB DDR3 SDRAM, provided by 4 2Gb chips. The mounting holes
and connectors are in the exact same position as on the Raspberry Pi B+.

Raspberry Pi B+ like peripherals supported on this board include:

  - Power input through micro-USB connector (without USB OTG)
  - Native 100 Mbps ethernet using the internal PHY, as opposed to
    USB-based on the RPi
  - 4x USB 2.0 host ports, directly connected to the SoC, as opposed to
    being connected through a USB 2.0 hub on the RPi
  - TV and audio output on a 3.5mm TRRS jack
  - HDMI output
  - Micro-SD card slot
  - Standard RPi B+ GPIO header, with the standard peripherals routed to
    the same pins.

    * 5V, 3.3V power, and ground
    * I2C0 on the H3 is routed to I2C1 pins on the RPi header
    * I2C1 on the H3 is routed to I2C0 pins on the RPi header
    * UART1 on the H3 is routed to UART0 pins on the RPi header
    * SPI0 on the H3 is routed to SPI0 pins on the RPi header,
      with GPIO pin PA17 replacing the missing Chip Select 1
    * I2S1 on the H3 is routed to PCM pins on the RPi header

  - Additional peripherals from the H3 are available on different pins.
    These include I2S0, JTAG, PWM1, SPDIF, SPI1, and UART3

In addition, there are a number of new features:

  - Console UART header
  - Consumer IR receiver
  - Camera interface (not compatible with RPi)
  - Onboard microphone
  - eMMC expansion module port
  - Heatsink mounting holes

This patch adds defconfig and dts files for this board. The dts file is
the same as the one submitted for inclusion in Linux, with some minor
revisions to match the dtsi file and old EMAC bindings in U-boot.

Since the OTG controller is wired to a USB host port, and the H3 has
proper USB hosts to handle host mode, the MUSB driver is not enabled.

arm: Exercise v7_arch_cp15_set_acr even without errata fixups

By applying this patch, we are ensuring that the code paths
responsible for applying errata workarounds are also exercised
on CPU revisions, which actually don't need these workarounds.

Only CONFIG_ARM_ERRATA_621766, CONFIG_ARM_ERRATA_454179,
CONFIG_ARM_ERRATA_725233 and CONFIG_ARM_ERRATA_430973 are
covered by this patch (Cortex-A8).

This improves code coverage when testing U-Boot builds
on newer hardware. In particular, the problematic commit
00bbe96ebabb ("arm: omap: Unify get_device_type() function")
would break both BeageBoard and BeagleBoard XM rather than
just older BeagleBoard.

As an additional bonus, we need fewer instructins and the SPL
size is reduced.
