To: u-boot; +Cc: GSS_MTK_Uboot_upstream, Daniel Schwierzeck, Weijie Gao
This patch adds support for MediaTek MT7621 SoC.
All files are dedicated for u-boot.
Currently only ramboot is supported.
The default build target is u-boot-lzma.img.
This file can be booted using bootm command, or be used as a payload of the
SDK preloader of MT7621.
The specification of this chip:
https://www.mediatek.com/products/homenetworking/mt7621
Signed-off-by: Weijie Gao <weijie.gao@mediatek.com>
---
v3 changes:
Update clock name for mt7621.dtsi due to clk driver changed
v2 changes:
Add a kconfig for max supported ram size
Remove network configs from default config file

The mt7621_rfb board supports integrated giga PHYs plus one external
giga PHYs. It also has up to 512MiB DDR3, 16MB SPI-NOR, 3 mini PCI-e x1
slots, SDXC and USB.
The mt7621_nand_rfb board is almost the same as mt7621_rfb board, but it
uses NAND flash and SDXC is not available.

OK. I'll remove this file and use mt7621.h instead.

This patch adds support for noncached_alloc() which was only supported by
ARM platform.
Unlike the ARM platform, MMU is not used in u-boot for MIPS. Instead, KSEG
is provided to access uncached memory. So most code of this patch is copied
from cache.c of ARM platform, with only two differences:
1. MMU is untouched in noncached_set_region()
2. Address returned by noncached_alloc() is converted using KSEG1ADDR()

This patch adds a clock driver for MediaTek MT7621 SoC.
This driver provides clock gate control as well as getting clock frequency
for CPU/SYS/XTAL and some peripherals.

Hello Weijie,
doesn't MT7621 U-Boot need a proprietary binary for DDR training?
I remember that it was required in 2016 for MqMaker WitiBoard.

Hi Marek,
Yes. MT7621 does need such a proprietary binary for DDR initialization
and calibration. That's why I submit only the ram-bootable part here.
I'm considering to create a preloader to load and run DDR init&calib
binary and ram-bootable u-boot image. The ram-bootable u-boot image can be appended to the proloader to form the flash-bootable bootloader.
The source code of preloader will be uploaded to github.
Best Regards,
Weijie

Just to be sure: You are not implementing this preloader as an U-Boot
SPL loader, as this would conflict with U-Boot's GPL compatibility?

Yes. Submitting the source code of this binary also violates MTK's non-
disclosure agreement.

Isn't it possible to submit the DDR training code in binary version,
and somehow call into it from SPL?

It's possible and I've already implemented it. But will u-boot accept
binary file?

U-Boot at least accepts drivers that require proprietary firmware to
load (bnxt driver, for example).
I don't know whether a binary firmware can be accepted into the U-Boot
repository, whether in a separate file or as an u8 array in a .c file,
but it should at least be possible to make it so that the user can
compile it thsemsevles to be bundled, i.e. create a Kconfig option that
configures a path to the firmware. If it is present, it will be
compiled with DDR training bundled.
Stefan, Tom, can this be done?
BTW, Weijie, can I already test this on mt7621 board, also with DDR
training? Can you send me the patch that adds calling the proprietary
code?

At the high level, I would make a further disappointed sigh and note the
NXP ddr firmware blobs, the binary blobs we pull in for x86, and all of
