c1125bad6c usb: hub: Fix usb_get_port_status() for big-endian platforms
Add missing endianness conversions to usb_get_port_status(). This
(amongst others) is necessary to enable the use of USB 3 hubs on
big-endian platforms like MIPS Octeon.

95a5825f31 dm: core: Add an option to support SPL in read-only memory

we would need to copy the devices to read/write memory.

To avoid this, add an option to use a separate runtime struct for devices,

changes at runtime, avoiding the need for a copy.

166363f2ed common: SCP03 control (enable and provision of keys)
This Trusted Application allows enabling SCP03 as well as provisioning
the keys on TEE controlled secure element (ie, NXP SE050).

All the information flowing on buses (ie I2C) between the processor
and the secure element must be encrypted. Secure elements are
pre-provisioned with a set of keys known to the user so that the
secure channel protocol (encryption) can be enforced on the first
boot. This situation is however unsafe since the keys are publically
available.

For example, in the case of the NXP SE050, these keys would be
available in the OP-TEE source tree [2] and of course in the
documentation corresponding to the part.

To address that, users are required to rotate/provision those keys
(ie, generate new keys and write them in the secure element's
persistent memory).

For information on SCP03, check the Global Platform HomePage and
google for that term [1]

[2] https://github.com/OP-TEE/optee_os/

9ad7a6c25c log: Handle line continuation

log prefix is prepended multiple times in the same line. This makes the

Fix this by detecting when the previous log record did not end in newline.
In that case, setting a flag.

To avoid expanding the log_record struct itself (which some drivers may

Update the code to use map_sysmem() instead.

As part of this change, the existing load_ptr is renamed to src_ptr since
it is not a pointer to load_addr. It is confusing to use a similar name
for something that is not actually related. For the alignment code,
ALIGN() is used instead of open-coded alignment. Add a comment to the line
that casts away a const.

device tree blob and etc loaded from FIT. After those images are
loaded from FIT, the VAB certificate and signature block appended
at the end of each image are sent to Secure Device Manager (SDM)
for authentication. U-Boot will validate the SHA384 of the image
against the SHA384 hash stored in the VAB certificate before
sending the image to SDM for authentication.

a932aa3c69 common: fdt_support: Support special case of PCI address in fdt_read_prop()
At present fdt_read_prop() can only handle 1 or 2 cells. It is
called by fdt_read_range() which may be used to read PCI address
from <ranges> for a PCI bus node where the number of PCI address
cell is 3. The <ranges> property is an array of:

  { <child address> <parent address> <size in child address space> }

When trying to read <child address> from a PCI bus node using
fdt_read_prop(), as the codes below:

    /* Read <child address> */
    if (child_addr) {
        r = fdt_read_prop(ranges, ranges_len, cell, child_addr,
                          acells);
        if (r)
            return r;
    }

it will fail, because the PCI child address is made up of 3 cells
but fdt_read_prop() cannot handle it. We advance the cell offset
by 1 so that the <child address> can be correctly read.

This adds the special handling of such case.

e036a1d227 fdt/sunxi: Remove OF_STDOUT_PATH
OF_STDOUT_PATH was meant to hold the devicetree path to the serial
console, to be put into the linux,stdout-path property of the chosen node.

The only user of that was sunxi, and it was actually wrong for years
there: the paths hardcoded in sunxi_common.h were not matching the DTs,
evident by the leading 0's in nodenames, which have been removed years
ago.

On top of that, "linux,stdout-path" is now deprecated for a while (Linux
commit 2a9d832cc9aae from November 2014), and also all modern DTs
(including those included in U-Boot) carry a "stdout-path" property
already.

So remove the stanza from sunxi_common.h, and, since this was the last
user, also remove the associated bits from the rest of U-Boot.

71551055cb spl: fit: Load devicetree when a Linux payload is found
When a FIT config specifies a devicetree, we should load it, no
questions asked. In the case of the "simple" FIT loading path, a
difficulty arises in selecting the load address of the FDT.

The default FDT location is right after the "kernel" or "firmware"
image. However, if that is an OP-TEE image, then the FDT may end up in
secure DRAM, and not be accessible to normal world kernels.

Although the best solution is to be more careful about the FDT
address, a viable workaround is to only append the FDT after a u-boot
or Linux image. This is identical to the previous logic, except that
FDT loading is extended to IH_OS_LINUX images.

When a desired configuration is not found, conf_node will have a
negative value. Thus the for loop will start at the root "/" node of
the image, print the "/description" property, and stop.

It appears the intent of the loop was to print the names of the
subnodes under "/configurations". We would need the offset to the
"/configurations" node, which is abstracted by fit_find_config_node().

This change agrees that abstracting the node offset is the correct
design, and we shouldn't be parsing the configurations manually. Thus

efc4ad0bc7 spl: fit: Drop 'length' argument to board_spl_fit_post_load()
The size is derived from the FIT image itself. Any alignment
requirements are machine-specific and known by the board code. Thus
the total length can be derived from the FIT image and knowledge of
the platform. The 'length' argument is redundant. Remove it.

eb5fd9e46c usb: kbd: destroy device after console is stopped
In case of IOMUX enabled it assumes that console devices in the list
are available to get them stopped properly via ->stop() callback.
However, the USB keyboard driver violates this assumption and tries
to play tricks so the device get destroyed while being listed as
an active console.

Swap the order of device deregistration and IOMUX update along with
converting to use iomux_replace_device() jelper to avoid the use-after-free.
