4bf56913d0 net: macb: Add support for Xilinx Zynq SoC
Although Xilinx Zynq SoC was using MACB similar hardware. However,
U-boot MACB driver was not supporting Xilinx Zynq SoC. This patch is
to add support for the Xilinx Zynq SoC to the existing MACB network
driver.

This patch is to add Zynq GEM DMA Config, provide callback
function for different linkspeed for case of using Xilinx Zynq
Programmable Logic as GMII to RGMII converter.

This patch convert the return value to use error codes.

"This function provides a safe path when image authentication has failed
and all possible boot paths have been exhausted. It is intended for use by
post-ROM boot stage components, via the ROM Vector Table."

Once invoked the part will drop down to its BootROM USB recovery mode.
Should it be the case that the part is in secure boot mode - only an
appropriately signed binary will be accepted by the ROM and subsequently
executed.

4467ae6c28 arm: imx: hab: Make authenticate_image() return zero on open boards
The BootROM will not successfully process a HAB image passed by u-boot
unless the board has been set into locked mode. Some of the existing usages
of authenticate_image() expect and rely on unlocked boards doing the
following

1. Not calling into the BootROM authenticate_image() callback
2. Returning a pass status for authenticate_image() calls anyway

A previous patch removed the necessity to call into imx_hab_is_enabled()
twice. This patch ensures the reliance on authenticate_image() returning
zero is maintained.

c5800b2541 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.

d2c61800fc arm: imx: hab: Optimise flow of authenticate_image on is_enabled fail
There is no need to call is_enabled() twice in authenticate_image - it does
nothing but add an additional layer of indentation.

We can check for is_enabled() at the start of the function and return the
result code directly.

9535b3975f arm: imx: hab: Fix authenticate_image result code
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.

adbb051f08 arm: imx: hab: Make authenticate_image return int
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.

5fed97af20 Makefile: ensure DTB doesn't overflow into initial stack
With CONFIG_SYS_INIT_SP_BSS_OFFSET enabled, the initial (pre-relocation)
stack is placed some distance after bss_start. The control DTB is appended
to the U-Boot binary at bss_start. If the DTB is too large, or the SP BSS
offset too small, then the initial stack could corrupt the DTB. Enhance
the Makefile to check whether this is likely to occur.

cdcf55584e ARM: Tegra186: don't map memory not in RAM banks
Tegra186 currently restricts its DRAM usage to entries in the /memory node
in the DTB passed to it. However, the MMU configuration always maps the
entire first 2GB of RAM. This could allow the CPU to speculatively access
RAM that isn't part of the in-use banks. This patch switches to runtime
construction of the table that's used to construct the MMU translation
tables, and thus prevents access to RAM that's not part of a valid bank.

Note: This patch is intended to prevent access to RAM regions which U-Boot
does not need to access, with the primary purpose of avoiding theoretical
speculative access to physical regions for which the HW will throw errors
(e.g. carve-outs that the CPU has no permission to access at a bus level,
bad ECC pages, etc.). In particular, this patch is not deliberately
related to the speculation-related security issues that were recently
announced. The apparent similarity is a coincidence.

In the future, the list of DRAM regions passed to U-Boot in the DTB may

regions to find the best region to relocate into, rather than relying on
the current assumption that the top of bank 0 is a reasonable relocation
target. This change implements such searching.

e6c904489a ARMv8: Allow dynamic early stack pointer
U-Boot typically uses a hard-coded value for the stack pointer before
relocation. Implement option SYS_INIT_SP_BSS_OFFSET to instead calculate
the initial SP at run-time. This is useful to avoid hard-coding addresses
into U-Boot, so that can be loaded and executed at arbitrary addresses and
thus avoid using arbitrary addresses at runtime. This option's value is
the offset added to &_bss_start in order to calculate the stack pointer.
This offset should be large enough so that the early malloc region, global
data (gd), and early stack usage do not overlap any appended DTB.

edc57f1df8 ARM: imx: cm_fx6: env: try to determine dtb to use
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.

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.
