[U-Boot] [PATCH v5 00/27] ARM: tegra: Miscalleneous improvements

[Thierry Reding]

From: Thierry Reding <treding@nvidia.com>

Hi Tom, Stephen,

this in the fifth installment of this series of miscellaneous
improvements for Tegra support. The main changes since the last version
are:

  - Add two patches from the "framebuffer carveout" series since Simon
    has already picked up the libfdt and fdtdec specific parts.
  - Fix the MAC address regression found by Stephen's test system. This
    is done by writing the MAC address to U-Boot's control DTB rather
    than storing it in the environment and thereby confusing Ethernet
    drivers if more than one device are present in the system.
  - I've also added the Jetson Nano patch to the series since it has
    changed slightly. The issue of the pinmux spreadsheet is still open,
    so this isn't quite ready to be merged, but I wanted to solicit more
    feedback, so that this is already reviewed by the time the pinmux
    spreadsheet issue is resolved.

Simon,

I've included another patch for a new fdtdec function in this series
because the first user is introduced here. It'd be great if you could
provide an Acked-by on the first patch so that Tom can pick it up and
send out as part of the PR for the entire series once it's been reviewed
and passed Stephen's test system.

The second patch is also required later in the series. There's no
explicit maintainer for lib/string.c, but you show up in the output for
scripts/get_maintainer.pl for the second patch, so perhaps you could
also give an Acked-by on that?

Alternatively you could pick up patches 1 and 2 so that Tom can base his
PR on your tree (or master, later on), if that's what you guys prefer.
Actually, this might be better anyway, since there might be a tiny merge
conflict between the fdtdec patch in this series and the other ones that
I sent out earlier.

Thanks,
Thierry

[U-Boot] [PATCH v5 01/27] fdtdec: Add fdtdec_set_ethernet_mac_address()

[Thierry Reding]

From: Thierry Reding <treding@nvidia.com>

This function can be used to set the local MAC address for the default
Ethernet interface in its device tree node. The default interface is
identified by the "ethernet" alias.

One case where this is useful is for devices that store their MAC
address in a custom location. Once extracted, board code can store the
MAC address in U-Boot's control DTB so that it will automatically be
used by the Ethernet uclass.

[U-Boot] [PATCH v5 03/27] ARM: tegra: Fix mux type for disp1 and disp2 clocks on Tegra210

[Thierry Reding]

From: Thierry Reding <treding@nvidia.com>

On Tegra210 the parents for the disp1 and disp2 clocks are slightly
different from earlier chips. Only pll_p, pll_d_out0, pll_d2_out0 and
clk_m are valid parents (technically pll_d_out is as well, but U-Boot
doesn't know anything about it). Fix up the type name and the mux
definition.

[U-Boot] [PATCH v5 04/27] ARM: tegra: Remove disp1 clock initialization on Tegra210

[Thierry Reding]

From: Thierry Reding <treding@nvidia.com>

pll_c is not a valid parent for the disp1 clock, so trying to set it
will fail. Given that display is not used in U-Boot, remove the init
table entry so that disp1 will keep its default parent (clk_m).

[U-Boot] [PATCH v5 11/27] ARM: tegra: Fix save_boot_params() prototype

[Thierry Reding]

From: Thierry Reding <treding@nvidia.com>

The save_boot_params() function takes as its first four arguments the
first four registers. On 32-bit ARM these are r0, r1, r2 and r3, all of
which are 32 bits wide. However, on 64-bit ARM thene registers are x0,
x1, x2 and x3, all of which are 64 bits wide. In order to allow reusing
the save_boot_params() implementation on 64-bit ARM, change it to take
unsigned long parameters rather than the fixed size 32-bit integers.
This ensures that the correct values are passed.

[U-Boot] [PATCH v5 12/27] ARM: tegra: Allow boards to override boot target devices

[Thierry Reding]

From: Thierry Reding <treding@nvidia.com>

Boards may not support all the boot target devices in the default list
for Tegra devices. Allow a board to override the list and default to the
standard list only if the board hasn't specified one itself.

[U-Boot] [PATCH v5 13/27] ARM: tegra: Support TZ-only access to PMC

[Thierry Reding]

From: Thierry Reding <treding@nvidia.com>

Some devices may restrict access to the PMC to TrustZone software only.
Non-TZ software can detect this and use SMC calls to the firmware that
runs in the TrustZone to perform accesses to PMC registers.

Note that this also fixes reset_cpu() and the enterrcm command on
Tegra186 where they were previously trying to access the PMC at a wrong
physical address.

Based on work by Kalyani Chidambaram <kalyanic@nvidia.com> and Tom
Warren <twarren@nvidia.com>.

[U-Boot] [PATCH v5 14/27] ARM: tegra: Workaround UDC boot issues only if necessary

[Thierry Reding]

From: Thierry Reding <treding@nvidia.com>

Resetting the USB device controller on boot is only necessary if the SoC
actually has a UDC controller and U-Boot enables support for it. All the
Tegra boards support UDC via the ChipIdea UDC driver, so make the UDC on
boot workaround depend on the ChipIdea UDC driver.

This prevents a crash on Tegra186 which does not have the ChipIdea UDC.

[U-Boot] [PATCH v5 15/27] ARM: tegra: Restore DRAM bank count

[Thierry Reding]

From: Thierry Reding <treding@nvidia.com>

Commit 86cf1c82850f ("configs: Migrate CONFIG_NR_DRAM_BANKS") reduced
the number of DRAM banks supported by U-Boot from 1026 to 8 on P2771-000
boards.

However, as explained in commit a9819b9e33bd ("ARM: tegra: p2771-000:
increase max DRAM bank count"), the platform can have a large number of
unusable chunks of memory (up to 1024), so a total of 1026 DRAM banks
are needed to describe the worst-case situation.

In practice the number of DRAM banks needed will typically be much
lower, but we should be prepared to properly deal with the worst case.

From: Thierry Reding <treding@nvidia.com>

Tegra186 build are currently dealt with in very special ways, which is
because Tegra186 is fundamentally different in many respects. It is no
longer necessary to do many of the low-level programming because early
boot firmware will already have taken care of it.

Unfortunately, separating Tegra186 builds from the rest in this way
makes it difficult to share code with prior generations of Tegra. With
all of the low-level programming code behind Kconfig guards, the build
for Tegra186 can again be unified.

As a side-effect, and partial reason for this change, other Tegra SoC
generations can now make use of the code that deals with taking over a
boot from earlier bootloaders. This used to be nvtboot, but has been
replaced by cboot nowadays. Rename the files and functions related to
this to avoid confusion. The implemented protocols are unchanged.

Signed-off-by: Thierry Reding <treding@nvidia.com>

Changes in v4:
- consistently use /chosen/nvidia,ether-mac property

Changes in v3:
- load cboot DTB address to fdt_addr instead of fdtaddr

[U-Boot] [PATCH v5 18/27] ARM: tegra: Implement cboot_get_ethaddr()

[Thierry Reding]

From: Thierry Reding <treding@nvidia.com>

This function will attempt to look up an Ethernet address in the DTB
that was passed in from cboot. It does so by first trying to locate the
default Ethernet device for the board (identified by the "ethernet"
alias) and if found, reads the "local-mac-address" property. If the
"ethernet" alias does not exist, or if it points to a device tree node
that doesn't exist, or if the device tree node that it points to does
not have a "local-mac-address" property or if the value is invalid, it
will fall back to the legacy mechanism of looking for the MAC address
stored in the "nvidia,ethernet-mac" or "nvidia,ether-mac" properties of
the "/chosen" node.

The MAC address is then written to the default Ethernet device for the
board (again identified by the "ethernet" alias) in U-Boot's control
DTB. This allows the device driver for that device to read the MAC
address from the standard location in device tree.

Signed-off-by: Thierry Reding <treding@nvidia.com>
---
Changes in v5:
- write MAC to DT rather than an environment variable

Changes in v4:
- also check the /chosen/nvidia,ethernet-mac property for compatibility
  with Tegra210

Changes in v2:
- make dummy static inline to avoid duplicate definitions

[U-Boot] [PATCH v5 20/27] ARM: tegra: Enable position independent build for 64-bit

[Thierry Reding]

From: Thierry Reding <treding@nvidia.com>

Note that U-Boot is always chainloaded from cboot starting with L4T
release 28. cboot always loads U-Boot to a fixed address, so making
the builds position independent isn't strictly necessary. However,
position independent builds can be convenient because if U-Boot is
ever loaded to an address different from its link address, it will
still be able to boot.

[U-Boot] [PATCH v5 21/27] p2371-2180: Pass Ethernet MAC to the kernel

[Thierry Reding]

From: Thierry Reding <treding@nvidia.com>

Pass the ethernet MAC address to the kernel upon boot. This passes both
the local-mac-address property (as passed to U-Boot from cboot) and the
currently set MAC address via the mac-address property. The latter will
only be set if it is different from the address that was already passed
via the local-mac-address property.

[U-Boot] [PATCH v5 23/27] p2371-2180: Add support for framebuffer carveouts

[Thierry Reding]

From: Thierry Reding <treding@nvidia.com>

If early firmware initialized the display hardware and the display
controllers are scanning out a framebuffer (e.g. a splash screen), make
sure to pass information about the memory location of that framebuffer
to the kernel before booting to avoid the kernel from using that memory
for the buddy allocator.

This same mechanism can also be used in the kernel to set up early SMMU
mappings and avoid SMMU faults caused by the display controller reading
from memory for which it has no mapping.

[U-Boot] [PATCH v5 25/27] ARM: tegra: Rename pcie-controller to pcie

[Thierry Reding]

From: Thierry Reding <treding@nvidia.com>

Recent versions of DTC have checks for PCI host bridge device tree nodes
that are named something other than "pci" or "pcie". Fix all occurrences
of such nodes for Tegra boards to avoid potential warnings from DTC.

[U-Boot] [PATCH v5 27/27] ARM: tegra: Add NVIDIA Jetson Nano Developer Kit support

[Thierry Reding]

From: Thierry Reding <treding@nvidia.com>

The Jetson Nano Developer Kit is a Tegra X1 based development board. It
is similar to Jetson TX1 but it is not pin compatible. It features 4 GB
of LPDDR4, an SPI NOR flash for early boot firmware and an SD card slot
used for storage.

HDMI 2.0 or DP 1.2 are available for display, four USB ports (3 USB 2.0
and 1 USB 3.0) can be used to attach a variety of peripherals and a PCI
Ethernet controller provides onboard network connectivity.

A 40-pin header on the board can be used to extend the capabilities and
exposed interfaces of the Jetson Nano.

Changes in v5:
- add "ethernet" alias and store an empty MAC address as placeholder

Changes in v3:
- rename "Development Kit" to "Developer Kit"
- drop alias for non-existent eMMC interface
- import pinmux from A02 spreadsheet
- drop preboot support for now
- fixup text base

[U-Boot] [PATCH v5 00/27] ARM: tegra: Miscalleneous improvements

[Tom Warren]

Thierry,

I tried applying your 27 v5 patchset series here to my local u-boot-tegra/master + uboot/master (on the assumption that Simon's FDT patches had made it to TomR's master), and it failed on the first patch w/git-am. Using 'patch' allowed it to be applied w/minor fixups/fuzz. The rest of the patches then applied w/git-am OK.

I'm building locally now (64-bit and 32-bit Tegra) and if all is well I'll send a new master to Denx (minus the Nano CL, since we're not yet ready to provide all the collateral docs) for Stephen's testframe to pick up, and if it all passes I can send it all to TomR in a PR later this week.

Tom

From: Thierry Reding <treding@nvidia.com>

Hi Tom, Stephen,

this in the fifth installment of this series of miscellaneous improvements for Tegra support. The main changes since the last version
are:

  - Add two patches from the "framebuffer carveout" series since Simon
    has already picked up the libfdt and fdtdec specific parts.
  - Fix the MAC address regression found by Stephen's test system. This
    is done by writing the MAC address to U-Boot's control DTB rather
    than storing it in the environment and thereby confusing Ethernet
    drivers if more than one device are present in the system.
  - I've also added the Jetson Nano patch to the series since it has
    changed slightly. The issue of the pinmux spreadsheet is still open,
    so this isn't quite ready to be merged, but I wanted to solicit more
    feedback, so that this is already reviewed by the time the pinmux
    spreadsheet issue is resolved.

Simon,

I've included another patch for a new fdtdec function in this series because the first user is introduced here. It'd be great if you could provide an Acked-by on the first patch so that Tom can pick it up and send out as part of the PR for the entire series once it's been reviewed and passed Stephen's test system.

The second patch is also required later in the series. There's no explicit maintainer for lib/string.c, but you show up in the output for scripts/get_maintainer.pl for the second patch, so perhaps you could also give an Acked-by on that?

Alternatively you could pick up patches 1 and 2 so that Tom can base his PR on your tree (or master, later on), if that's what you guys prefer.
Actually, this might be better anyway, since there might be a tiny merge conflict between the fdtdec patch in this series and the other ones that I sent out earlier.

Thanks,
Thierry
