d6a6dd9079 video: panel: add Samsung LTL106HL02 MIPI DSI panel driver
LTL106HL02 is a color active matrix TFT (Thin Film Transistor)
liquid crystal display (LCD) that uses amorphous silicon TFT as
switching devices. This model is composed of a TFT LCD panel, a
driver circuit and a backlight unit. The resolution of a 10.6"
contains 1920 x 1080 pixels and can display up to 16,8M color
with wide viewing angle.

3cb31745c4 video: panel: add LG LG070WX3 MIPI DSI panel driver
The LD070WX3 is a Color Active Matrix Liquid Crystal Display with
an integral Light Emitting Diode (LED) backlight system. The
matrix employs a-Si Thin Film Transistor as the active element. It
is a transmissive type display operating in the normally Black
mode. This TFT-LCD has 7.0 inches diagonally measured active
display area with WXGA resolution (800 by 1280 pixel array).

8c0eb06fbe video: tegra20: dc: configure behavior if PLLD/D2 is used
If DISP1 is a PLLD/D2 child, it cannot go over 370MHz. The cause
of this is not quite clear. This can be overcomed by further
halving the PLLD/D2 if the target parent rate is over 800MHz.
This way DISP1 and DSI clocks will have the same frequency. The
shift divider in this case has to be calculated from the
original PLLD/D2 frequency and is passed from the DSI driver.

b9ef623c11 video: tegra20: dc: pass DC id to internal devices
Tegra SoC has 2 independent display controllers called DC_A and
DC_B, they are handled differently by internal video devices like
DSI and HDMI controllers so it is important for last to know
which display controller is used to properly set up registers.
To achieve this, a pipe field was added to pdata to pass display
controller id to internal Tegra SoC devices.

52c62acc34 x86: all firmware tables must be paragraph aligned
On qemu-x86_64_defconfig the following was observed:

    => efidebug tables
    00000000000f0074  eb9d2d31-2d88-11d3-9a16-0090273fc14d  SMBIOS table

The SMBIOS configuration table does not point to a paragraph-aligned
(16 byte aligned) address. The reason is that in write_tables() rom_addr is
not aligned and copied to gd->arch.smbios_start.

The Simple Firmware Interface requires that the SFI table is paragraph-
aligned but our code does not guarantee this.

As all tables written in write_tables() must be paragraph-aligned, we
should implement the address rounding in write_tables() and not in table
specific routines like copy_pirq_routing_table().

Add paragraph-alignment in write_tables().

85177b2cf4 efi_selftest: add tests for setvariableRT
Since we support SetVariableRT now add the relevant tests

- Search for the RTStorageVolatile and VarToFile variables after EBS
- Try to update with invalid variales (BS, RT only)
- Try to write a variable bigger than our backend storage
- Write a variable that fits and check VarToFile has been updated
  correclty
- Append to the variable and check VarToFile changes
- Try to delete VarToFile which is write protected
- Try to add/delete runtime variables
- Verify VarToFile contains a valid file format

00da8d65a3 efi_loader: add an EFI variable with the file contents
Previous patches enabled SetVariableRT using a RAM backend.
Although EBBR [0] defines a variable format we can teach userspace tools
and write the altered variables, it's better if we skip the ABI
requirements completely.

So let's add a new variable, in its own namespace called "VarToFile"
which contains a binary dump of the updated RT, BS and, NV variables
and will be updated when GetVariable is called.

Some adjustments are needed to do that.
Currently we discard BS-only variables in EBS(). We need to preserve
those on the RAM backend that exposes the variables. Since BS-only
variables can't appear at runtime we need to move the memory masking
checks from efi_var_collect() to efi_get_next_variable_name_mem()/
efi_get_variable_mem() and do the filtering at runtime.

We also need an efi_var_collect() variant available at runtime, in order
to construct the "VarToFile" buffer on the fly.

All users and applications (for linux) have to do when updating a variable
is dd that variable in the file described by "RTStorageVolatile".

Linux efivarfs uses a first 4 bytes of the output to represent attributes
in little-endian format. So, storing variables works like this:

$~ efibootmgr -n 0001
$~ dd if=/sys/firmware/efi/efivars/VarToFile-b2ac5fc9-92b7-4acd-aeac-11e818c3130c of=/boot/efi/ubootefi.var skip=4 bs=1

bc3dd2493e efi_loader: Add OS notifications for SetVariable at runtime
Previous patches enable SetVariable at runtime using a volatile storage
backend using EFI_RUNTIME_SERVICES_DATA allocared memory. Since there's
no recommendation from the spec on how to notify the OS, add a volatile
EFI variable that contains the filename relative to the ESP. OS'es
can use that file and update it at runtime

c28d32f946 efi_loader: conditionally enable SetvariableRT
When we store EFI variables on file we don't allow SetVariable at runtime,
since the OS doesn't know how to access or write that file.  At the same
time keeping the U-Boot drivers alive in runtime sections and performing
writes from the firmware is dangerous -- if at all possible.

For GetVariable at runtime we copy runtime variables in RAM and expose them
to the OS. Add a Kconfig option and provide SetVariable at runtime using
the same memory backend. The OS will be responsible for syncing the RAM
contents to the file, otherwise any changes made during runtime won't
persist reboots.

It's worth noting that the variable store format is defined in EBBR [0]
and authenticated variables are explicitly prohibited, since they have
to be stored on a medium that's tamper and rollback protected.

Currently efi_initrd_deregister() is called in bootefi.c
when the image started from bootefi command returns.
Since efi_guid_event_group_return_to_efibootmgr event is
implemented, so let's use this event for invoking
initrd deregistration.
