[PATCH 0/5] allow boot firmware to go in user/boot0/boot1

[PATCH 0/5] allow boot firmware to go in user/boot0/boot1

[Tim Harvey]

The Gateworks Venice board family uses a combination of imx8mm, imx8mn,
and imx8mp SoC's. Because boot firmware for these are not binary
compatible and have different flash offsets it is highly desirable to
place boot firmware in an emmc boot partition instead of the current
user hardware partition to minimize unintended corruption of boot
firmware by flashing the wrong image or to the wrong location.

This series of patches allows the same boot firmware to be placed in
either boot0, boot1, or user hardware partition by detecting the boot
device and adjusting env device as well as u-boot sector.

Additionally the firmware script is updated to automate device, offset,
and soc.

[PATCH 1/5] board: gateworks: venice: dynamically determine U-Boot raw sector

[Tim Harvey]

CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR needs to adjust for
IMX8MN and IMX8MP when booting from an eMMC boot partition due
to IMX BOOTROM v2 using an SPL offset of 0 for boot partitions
and 32K for the user partition.

In order to allow the same firmware to run on both user and boot
hardware partitions adjust raw_sect dynamically at runtime.

[PATCH 2/5] board: gateworks: venice: dynamically determine U-Boot env partition

[Tim Harvey]

Determine the U-Boot env hardware partition depending on the boot
device.

This allows the same boot firmware image to be placed on user, boot0,
or boot1 without changing CONFIG_SYS_MMC_ENV_PART.

[PATCH 3/5] board: gateworks: venice: dynamically update the update_firmware script

[Tim Harvey]

The update_firmware script is intended to update the boot firmware but
the details including the offset and hardware partition are dependent
on the boot device.

Specifically:
- IMX8MM/IMX8MP (BOOTROM v2) the offset is 32KiB for SD and eMMC user
  hardware partition and 0KiB for eMMC boot partitions.
- IMX8MM the offset is 33KiB for SD and eMMC regardless of hardware
  partition.

Dynamically set soc, dev, bootpart, and bootblk env vars at runtime
and use these in the update_firmware script. Remove the splblk env var
from config files as its no longer needed.

[PATCH 4/5] board: gateworks: venice: move env location

[Tim Harvey]

To allow U-Boot to fit within emmc boot partitions move the env from
just under 16MiB to just under 4MiB as some emmc devices used on venice
boards have 4MiB boot partitions. This still leaves plenty of room for
U-Boot.

Update the venice board documentation to show how to install to the
various eMMC hardware partitions available as the same binary firmware
can be placed in either user/boot0/boot1 without build-time config
changes. Note that the boot offsets differ depending on the SoC and the
eMMC hardware partition.
