[PATCH v2 0/4] Add support for RAM boot from maskrom mode

[PATCH v2 0/4] Add support for RAM boot from maskrom mode

[Jonas Karlman]

The BootROM in Rockchip SoCs will enter maskrom mode when boot firmware
cannot be found in nand/spi/mmc storage.

In maskrom mode the USB OTG port can accept one of two custom commands.

Initially a 0x471 command to load TPL into SRAM. After TPL has been
executed and it has returned back-to-BROM, a 0x472 command to load SPL
into start of DRAM.

This series adds two binman images that can be used to RAM boot from
maskrom mode:
- u-boot-rockchip-usb471.bin that contains TPL to init DRAM.
- u-boot-rockchip-usb472.bin that contains SPL and the normal FIT
  payload with i.e. U-Boot proper, TF-A and FDT.

These images can be used with rkbin tools/boot_merger to create a loader
image to be used with rkdeveloptool or rockusb tools, e.g.:

  Create loader image:
    $ ../rkbin/tools/boot_merger ./RK3588MINIALL.ini

  Boot from maskrom:
    $ rkdeveloptool db u-boot-rockchip-rk3588-loader.bin
   or
    $ rockusb download-boot u-boot-rockchip-rk3588-loader.bin

Or directly with tools such as rkflashtool or rkusbboot:

  $ rkflashtool l < u-boot-rockchip-usb471.bin
  $ rkflashtool L < u-boot-rockchip-usb472.bin
 or
  $ rkusbboot u-boot-rockchip-usb471.bin u-boot-rockchip-usb472.bin

Changes in v2:
- Rebase on top of "rockchip: binman: Use a template for FIT and other
  improvements" series
- Add patch to fix booting into Linux on RK3588 board with 16+ GiB DRAM

This series depends on the "rockchip: ROCKCHIP_COMMON_STACK_ADDR
improvements" series [1] and the "rockchip: binman: Use a template for
FIT and other improvements" series [2]. See [3] for a branch including
both depends.

[PATCH v2 1/4] rockchip: Move TEXT_BASE to 8 MiB offset from start of DRAM

[Jonas Karlman]

Drop SoC specific TEXT_BASE and use a common TEXT_BASE for all SoCs.

Move the common TEXT_BASE to 8 MiB offset from start of DRAM to help
support RAM boot from maskrom introduced in next patch.

RAM boot from maskrom mode will expect the FIT payload to be located at
2 MiB offset from start or DRAM.

The BootROM in Rockchip SoCs will enter maskrom mode when boot firmware
cannot be found in nand/spi/mmc storage.

In maskrom mode the USB OTG port can accept one of two custom commands.

Initially a 0x471 command to load TPL into SRAM. After TPL has been
executed and it has returned back-to-BROM, a 0x472 command to load SPL
into start of DRAM.

Add two binman images that can be used to RAM boot from maskrom mode:

- u-boot-rockchip-usb472.bin that contains SPL and the normal FIT

These images can be used with rkbin tools/boot_merger to create a loader
image to be used with rkdeveloptool or rockusb tools, e.g.:

  Create loader image:
    $ ../rkbin/tools/boot_merger ./RK3588MINIALL.ini

    $ rockusb download-boot u-boot-rockchip-rk3588-loader.bin

Or directly with tools such as rkflashtool or rkusbboot:

  $ rkflashtool l < u-boot-rockchip-usb471.bin
  $ rkflashtool L < u-boot-rockchip-usb472.bin

[PATCH v2 3/4] rockchip: Enable RAM boot using ROCKCHIP_MASKROM_IMAGE

[Jonas Karlman]

Imply ROCKCHIP_MASKROM_IMAGE to build maskrom RAM boot images for
RK3308, RK3328, RK3399, RK356x and RK3588.

These are SoCs that have fully migrated to COMMON_STACK_ADDR and that
I have been able to runtime test maskrom RAM boot on.

An alternative approach could be to add a rockchip_ramboot.config that
enables the ROCKCHIP_MASKROM_IMAGE Kconfig symbol.

[PATCH v2 4/4] rockchip: sdram: Add fallback that fixup DRAM gaps on RK3588

[Jonas Karlman]

RK3588 has two known memory gaps when using 16+ GiB DRAM,
[0x3fc000000, 0x3fc500000) and [0x3fff00000, 0x400000000).

The vendor TPL blob encodes this information in the DDR_MEM tag data
passed to later boot phases. U-Boot proper will normally use this
information to configure the DRAM banks.

When a DDR_MEM tag cannot be found the fallback is to use the entire
range above 4 GiB. Something that will cause issues when OS try to use
memory from the two known memory gaps.

Add a weak dram init banksize fixup function and implement it for RK3588
to fix issues observed when trying to RAM boot RK3588 boards with 16+
GiB DRAM into Linux.

I would just note that doc/README.rockchup should have any content not

Re: [PATCH v2 2/4] rockchip: Add support for RAM boot from maskrom mode

Hi Jonas,


     Thanks for your patch, and the ramboot with usb download do help 
bootloader developers.

This makes things quite complicated, needs so many new binaries and 
tools which

lead to confuse to users.

Let's make it simple for RAM boot with usb download so that user can use 
it easily:

use rkdeveloptool to download the loader and boot from RAM, and that's all.


Thanks,

It requires boot_merger which is not included in U-Boot, right?
