  arm: mach-bcm283x: Define configs for RaspberryPi 4
  arm: mach-bcm283x: Define mbox address for BCM2838
  rpi: Add rpi_model entry for RaspberryPi 4
  dt-bindings: Define BCM2838_CLOCK_EMMC2 needed for RaspberryPi 4
  arm: bcm283x: Include definition for additional emmc clock
  arm: bcm283x: Define device base addresses for bcm2835
  config: rpi4: Add defconfig for rpi4-32
  dts: bcm2838-rpi-4-b: Use the emmc2 interface for sdhci
  rpi: Add memory map for bcm2838
  configs: rpi4: Remove DWC2 and USB_ETHER configs
  dts: bcm2838-rpi-4-b: Use the emmc2/2811 compatible string for SDHCI

[U-Boot] [PATCH 01/16] dts: Create a dtsi for BCM2835/6/7 specific configuration

[andrei at gherzan.ro]

From: Andrei Gherzan <andrei@gherzan.ro>

This follows a similar change in kernel[1]. The change moves
configuration that was not applicable for all bcm2835/6/7/8 out of
bcm283x.dtsi. The new file is bcm2835-common.dtsi and contains
conifguration that is common for bcm2835/6/7 (not bcm2838).

My opinion is that we should wait for official dts instead of using some
work-in-progress ones. So my opinion is to use the DTB from the FW for now until
we have something stable.

[U-Boot] [PATCH 06/16] dt-bindings: Define BCM2838_CLOCK_EMMC2 needed for RaspberryPi 4

[andrei at gherzan.ro]

From: Andrei Gherzan <andrei@gherzan.ro>

On BCM2838 there is an additional clock. This clock was added in the
same bcm2835-cprman driver and is used by the emmc2 dt node.

Network is attached to a PHY not via PCI, that would be the USB.

It seems they're removed in patch 15 but the two should be squashed together.

Commit message.
You fix a file that you introduced in this series. Any reason why you don't just
send the file already fixed?

[U-Boot] [PATCH 15/16] configs: rpi4: Remove DWC2 and USB_ETHER configs

[andrei at gherzan.ro]

From: Andrei Gherzan <andrei@balena.io>

dwc2 is only connected to the usb-c port so we don't have any real
benefit in having it enabled in uboot.

Also, the GENET interface is connected directly to the SoC so we can
drop the USB_ETHER configs.

I don't understand why you posted these while you asked me if I'll submit them.
That's not a good way to collaborate on upstream.

Please use get_maintainers.pl to see whom you have to send the patches to.

Both not needed with FW at

Apart from that they have already been posted.

As I have mentioned privately, I've done that due to the fact that I haven't gotten any feedback from you. Nevertheless, I will sync up with you for the next iteration for this PR which will include the changes requested.

   - Removed known unsupported/not applicable peripherals (i.e USB) from
     defconfigs
   - Make sure the memory/reg is left untouched as configured by the
     firmware

[U-Boot] [PATCH v2 1/8] RPI: Add defconfigs for rpi4 (32/64)

[Andrei Gherzan]

This defines a minimum defconfig for each of the two Raspberry Pi 4
variants. One notable difference is that we don't have a embedded dt for
this board given that the fw supplies us with one which we can reuse.
Furthermore, the ram size is not queryable through mbox interface as the
maximum reported size is 1G. The fw patches the dt with the right
memory configuration and uboot uses it as it is. We avoid u-boot
touching this configuration by making sure CONFIG_ARCH_FIXUP_FDT_MEMORY
is deactivated.

[U-Boot] [PATCH v2 2/8] ARM: bcm283x: Add BCM283x_BASE define

[Andrei Gherzan]

From: Matthias Brugger <mbrugger@suse.com>

Devices of bcm283x have different base address, depending if they are on
bcm2835 or bcm2836/7. Use BCM283x_BASE depending on the SoC you want to
build and only add the offset in the header files.

How hard would it be to make the base a global variable instead and just 
set it early on board init based on the FDT or maybe even CPU core 
revision registers?

That would allow us to support RPi3 & 4 with the same U-Boot binary.

Yeah, then you only need to do the memory map dynamically as well and 
the rest should all be handled by DT :). Which again means you don't 
need a new config target at all!

I like that. It will bring a little confusion though when using a rpi3
defconfig for rpi4. I guess we could just copy it.

I have a working POC of this feature, but it needs more time. I propose to merge
RPi4 support now, so that it can get accepted for v2019.10. Afterwards we can
implement a unified u-boot binary for RPi[34] and maybe even RPi[12] in the future.

If nobody shouts I'll merge this series fixing the two comments I had.
Please let me know if you disagree.

Matthias

[U-Boot] [PATCH v2 3/8] ARM: bcm283x: Define configs for RaspberryPi 4

[Andrei Gherzan]

Define two target configs for Raspberry Pi 4 (32 and 64bit) and the
corresponding BCM2838* configs.

Be aware of the current limitation in firmware which requires an
explicit configuration to force the arm in 64bit mode when the
respective target is used.

In upstream kernel the SoC uses bcm2711 as identifier. So this get's messy here,
because we have all the bcm283x stuff. Anyway we should try to keep the
confusion as low as possible, so I propose to rename all BCM2838 in here to BCM2711.

It's not perfect but I think it's the best we can get right now.

Matthias

[U-Boot] [PATCH v2 6/8] mmc: bcm283x: Add support for bcm2711 device in bcm2835_sdhci

[Andrei Gherzan]

From: Matthias Brugger <mbrugger@suse.com>

The bcm2711 has two emmc controllers. The difference is the clocks
they use. Add support for the second emmc controller.
